Webasto hair dryer DIY repair

In detail: do-it-yourself webasto hair dryer from a real master for the site my.housecope.com.

The Webasto autonomous heater is a very reliable device, but a breakdown can still happen. In most cases, failure is due to improper installation, improper operation, or lack of maintenance.

Most often, the Webasto autonomous heater simply does not turn on in the event of a malfunction, however, with some malfunctions, an abnormal operation of the device is simply observed.

Autonomy Webasto has the following typical faults:

flame breaks;
overheat;
unstable work (for example, startup difficulties).

In the event of a breakdown, the heater will signal its malfunction by showing an error code (a table with codes is presented at the end of the article).

The timer display will show an inscription in the form of the letter F and two numbers (this is the error code).

If there is no timer and there is only a switch, then the switch lamp will give a certain signal (blink code). The light will give 5 short signals and a number of long ones. The number of long beeps is an error code. If the error code is 0, then the light will simply give 5 short beeps.

Also, abnormal operation of the heater may be indicated by extraneous noises during the operation of the device.

The car owner himself can only check the condition of the fuses, as well as visually assess the condition of the heater.

Therefore, if visually all the fuses are intact and all the plugs are in place, then it is necessary immediately contact a specialized service center... To fully diagnose and read errors, you need a special Webasto Thermo Test software, as well as a special programmer and an adapter plug. All this is available only in a specialized service center.

Self-repair can damage the heater or the vehicle.

Autonomy Webasto can show the following error codes:

Webasto is an irreplaceable thing in the modern world. Happy owners of such a device avoid serious problems in winter. But as soon as the system disappears, the question arises, why does the webasto not turn on? In the article we will try to analyze the possible causes of the breakdown, but first we will consider how to use the mechanism correctly so as not to further experience problems with the heater.

Webasto system in the car

Today it is difficult to find a car enthusiast who does not dream of embedding Webasto in his car. Webasto is a German-made autonomous pre-heater. A compact mechanism weighing 5 kg is installed inside the circuit of the on-board network cooling device and the vehicle fuel system. The main function of Webasto is to warm up the engine before starting the power unit. An independent heater pump drives antifreeze throughout the entire cooling network through the radiator. In fact, the device is a small combustion chamber connected to the vehicle's cooling system. Today, the manufacturer brings to the market two types of devices - Thermo Top Evo-4 and Thermo Top Evo-5... They differ only in power.

Webasto is also connected to the standard interior heater and starts the fan. Thus, in the cold season, the driver does not need to wait for the engine to warm up. The motor reaches the required temperature with one push of the remote control button. The owner does not need to approach the car, you can launch the webasto from the window of the apartment. Also, on cold start engine wear is equal to a mileage of 100 km... The heater works autonomously, heating and long starting of the engine does not take a large battery charge. The only obvious drawback is that the battery life is reduced by a year.If you take this as payment for convenience and comfort, then changing the battery is not decisive.

Webasto work in winter

In order for the device to serve a long operational life, and you do not diagnose Webasto with your own hands, you need to follow the attached instructions and tips:

parts of the mechanism should not come into contact with liquid;
no electric charges should act on the parts of the device;
it is forbidden to work at high humidity and temperature;
turn off the heater at the gas station;
using webasto in closed garages is prohibited;
use fuel supplied by the manufacturer;
the device needs to be started occasionally with an unheated engine at a lower fan power for about 10 minutes;
the heater can only work for an hour, you should not start it often.

When Webasto does not start after a summer downtime, many believe that they can easily repair the system on their own. This is far from the case, because, like any other mechanism, the heater has a swirling system. When you do not understand anything about electrics, it is worth contacting the company's diagnostic center - this will save you from a more round cost. If you have an idea of \ u200b \ u200bthe work of a mechanic and are ready to take the risk, then you should start by familiarizing yourself with the manufacturer's scheme. Check the simplest parts of the mechanism, perhaps the reason lies there.

One of the varieties of webasto

Work failures are divided into types:

Errors in internal memory... As a rule, they do not affect the operating mode.
Spontaneous crashes... Autostart or secondary inclusion is covered in the device diagram.
Shutdown by mistake... There is a failure in the control panel or power supply. The heating switches itself off without saving the error. The second variant of failure, when the error persists, and restarting asks for a signal to shutdown and to restart the system.
Blocking webasto... Occurs due to a recurring error. The failure must occur 4-6 times and then the unit is locked and saves the report. It is impossible to unlock the mechanism yourself, you should contact the service center. Note that if the malfunctions are due to low voltage or a damaged battery, there is no blocking.
Overheating lock... When the webasto overheats, the system locks up.
Shutdown by mistake due to low or high voltage... When the voltage reaches 11.5V, the mechanism turns off for a while. After that, a purge occurs. The voltage can be measured by the control unit. When the voltage is overestimated, it is measured with a heater. Usually, at 16V voltage, operation is suspended, shutdown and purging occurs. If the problem is resolved, the system is ready to serve again.

When the Webasto does not start, other causes are determined using the Thermo Test PC diagnostics.

Elimination of errors.

Common crash causes are sorted by type:

Unsaved errors. First, the fuel supply is checked, and only then the heater or connecting units are changed.
Fixed crashes. They look at the type of problem in the device's memory, a faulty node is shown there. Further, the breakdown is eliminated by replacing the part.
General saved faults. When webasto did not detect the broken part of the system. The first thing to look at is the peripheral parts of the mechanism.
View information about the error using PC diagnostics.

Fuel... Often the problems lie in the fuel supply. This happens in the winter, when many drivers forget to change the summer diesel fuel to the winter one. See the heater, it can work in a warm room, so take care of the garage. When the webasto is gone in a warm place, change the fuel. First, drain the diesel fuel, blow through the system, clean it, change the filter, pour in new diesel fuel. There is another reason for not entering the fuel into the heater. The diesel fuel does not reach the pump. The sound is clear and loud. There may also be air leaks when the fuel line is damaged. In addition, you need to check the solenoid valve, there is an accumulation of plugs in it.To check the air pressure on the winding, we take an ohmmeter. Normal units range from 136-154 ohms... When diagnosing, add any flushing fluid to the tube.

Electrician ringing... After checking the fuel system, people who understand electrics go further, and the average driver turns to service craftsmen. We look at the fuses F1-F3, if there are blown ones, we replace them and check for operability. Next, we check the timer. We measure its current in the connector, if there is no current supply, then the timer should be changed completely. The next object of control is the stove. We look at the terminals along the way, when they oxidized, this can block the supply of current. We look at the integrity of all wires. Depressurization most often occurs on the plug itself.

Webasto operating instructions

Removing blocks... Webasto may turn on blocking due to the fact that errors have been fixed, and reports about them did not have time to be recorded in the memory panel. We remove power from the control unit for 3 secondsremoving it from the fuse. We take out the chip and return it to its place. Then we turn on the heater. Then we repeat the first two steps of the manipulation. If everything went well, the system will work.

Tell us about Fiat Ducato Club

I decided to share some experience of parsing, collecting and eliminating one of the causes of problems in Webasta's work. It all started with the banal. When buying a car 5 years ago, the car did not even show signs that there was a Webasta on it. And now everyone knows, because it works like a tractor. So the day has come when it is necessary to remove it and make an audit. At first, suspicions were about a dying air blower.
Having enlisted the support of GIB2D “Dimon, do not shout. After disassembling and assembling it, you will laugh at yourself for a long time that you were afraid to tear it apart. Everything is nowhere easier there. " crawled under the car.
Better to be prepared and purchase a repair kit for gaskets in advance.

We climb under the car with a 13 ratchet, large side cutters, clamps and a small container for antifreeze. We disconnect the supply and return hose at the place of the coupling, which was previously drawn in with clamps. The couplings are located at a distance of about 50 cm from the webast at the transition of the webast hose to the standard hoses. If you pick up the clamp on the clamp with side cutters, then it is removed with a bang. I later used them again. Antifreeze will be about 300-500 ml. Further, having a piece of hose with an inner diameter of 16-18 mm and two clamps, we loop the hoses if there is a need to use a car. We also remove the clamp from the diesel fuel supply hose. The power supply, if the chip is cut off, can be removed directly from the boiler.

For ease of cleaning, it is better to remove all hoses from the boiler itself. Take a wd or liquid wrench and preprocess all the bolts. One bolt of the brain cover broke off from overheating. I had to spend time drilling it. If there is no need and there is no urge that the brains of the boiler fucking. t brain, then there is no point in throwing off the lid over the brain. Everything is hermetically sealed there.
We take the bat with a star (25) and begin parsing.
We divide the webasta into three parts: a fan in the case, a burner in the case, and a heat exchanger. Here are some pictures of why you need to clean the Webasta in a timely manner.

The photo shows how everything is in soot and coke. The camera near the pin was especially damaged. Everything was uprooted about 1 matchbox of coke and carbon deposits. On a tip from the forumer "smirnov" the burner was cut. There are three legs. Having cut the legs and removing the staples holding the pin, it disassembles the camera into two parts. Now there is access to thoroughly clean everything. On the pictures you can see a bracket that holds two tablets through which fuel flows and ignites. By removing the bracket, it was possible to turn them over to the cleaner side. I cleaned everything with an ABRo carburetor cleaner. We boiled it back with an automatic machine. After cleaning, everything shines like new.
Before cleaning

The fan casing is essentially not collapsible. The only thing I could do was to drop some oil on the shaft through the plug on the body.
When assembled, the kit includes four spacers. Two rubber, paronite and paper. Depending on the year of issue of the webast, rubber or paper is used when connecting the fan and burner unit. It makes no sense to look for a place where to vpendyur both.
When installing the webast in place, I also decided to remake the place where the power supply and control of the webast were connected. Was put together like this last winter.

I want to note that only the compound (and it turned out to be a mass) was protected from oxidation. Everything else was already black. Having cleaned and soldered everything, I drove it into an adhesive heat shrinkage.

For the convenience of soldering, you can remove the clamp holding the hoses and power in the area of the tank and then there will be enough wire to pull it out from under the car.

The result of the work. The sound of the webastoy was previously eliminated, but not completely. It may need to be replaced later. So do not make premature conclusions about a malfunction of the air blower or other parts of the webast.

Many owners of the well-known Webasto pre-heaters are faced with the fact that during normal operation of the heater, suddenly it does not want to start or it starts up and stalls. This means that it is blocked, and now we have to answer the question: "How to unblock Webasto?" Blocking Webasto occurs as a result of an error in the electronic control unit, which may be caused by a loss of contact with any sensor, incorrect sensor readings due to its breakdown, or a short to ground. This is done to preserve the operability of the main units of the heater and protect them from possible breakdown, because it is much cheaper to get off with the purchase of a new sensor than a pump or even worse combustion chamber.

In order for the pre-heater to work again, it is necessary to eliminate the malfunctions that have arisen and erase the errors.

When Webasto is blocked, when it is turned on again, the control lamp flashes several times, which are repeated after a certain period of time - this is the error code that denotes a certain type of malfunction. The code can be deciphered using the service book that this heater comes with. Now, having eliminated the malfunction, you can safely proceed to erasing the error.
Depending on the model of the heater and the vehicle on which it is installed, there are different ways to unblocking Webasto.
On rather outdated models, you need to briefly de-energize Webasto by disconnecting the battery from the car, and in some, disconnect the main fuse for a few seconds, then reconnect it. However, in most new models, Webasto is unlocked by connecting to a computer with special software that reads the error code, decrypts it and, if necessary, deletes it from the memory of the electronic control unit.

Software for unlocking the Webasto heater

Since not every owner has a special cable and software with him, you should contact a service station, where experienced craftsmen will unlock Webasto.
There is another universal way to remove the Webasto lock, suitable for most heater models. You need to turn off the heater, disconnect its main fuse, turn on the ignition and start the car. After the car has worked a little, you can turn it off, and after connecting the fuse, try to restart Webasto.
If this method did not help, then you can repeat the procedure several more times, but if this time the attempt was unsuccessful, then you should contact the Webasto service center.

Summing up the results of this material, it is worth noting that with proper operation, timely and high-quality service, pre-heaters will last a long time and will only delight their owner.

The problem of starting a cold engine start at low temperatures is well known to every car owner. The power unit hardly starts up in cold weather, the degree of wear of loaded engine parts increases during such starts. Also, in winter, the comfort of vehicle operation is significantly reduced, since the warm-up time of the internal combustion engine and the interior space to an acceptable level can be significantly increased.

To effectively solve these problems, the car can be equipped with a pre-heater. There are several types of such devices, while the best autonomy and performance are possessed by liquid engine heaters of the Webasto type.

In this article, we intend to talk about how much Webasto costs with the installation, what features and nuances the installation of Webasto on a gasoline engine or diesel unit involves, and also how to install Webasto on a car yourself.

So, if the car is operated in a region with frosty and long winters, is used in such conditions as a commercial vehicle, the driver wants to increase the comfort of use in winter, etc., then the question of installing a pre-heater becomes especially relevant.

In the case of Webasto, the answer will be in the affirmative, even taking into account the rather high initial cost of such a heater and its installation. On average, buying and delivering Webasto will cost from 40 to 100 thousand rubles. for the device itself (depending on the type of vehicle), as well as about 15 thousand rubles. for installation.

However, such a pre-heater will allow the engine to start in any frost, and the total resource of the internal combustion engine increases. We also note that the warming up of the engine and the passenger compartment with an autonomous heater before the trip is noticeably reduced, which allows us to talk about fuel economy (especially in relation to gasoline cars).

On diesel engines, the Webasto installation allows you to solve the well-known problem of diesel fuel, which thickens in cold weather. It turns out that the installation of preheating is more or less profitable from an economic point of view, since fuel consumption is reduced, the engine is subject to less wear, which reduces the cost of repairing it.

For maximum savings, many drivers (especially owners of cars and small commercial vehicles) also prefer to install the specified equipment on their own. In other words, you will need a Webasto kit, installation instructions, the necessary tools and a place for work (it is advisable to have a garage with a lift or a pit).

To begin with, installing Webasto with your own hands involves a whole range of operations. If you are not confident in your abilities, do not have sufficient experience and suitable tools, then it is better to refuse from self-installation and turn to a professional installation center for help.

It should be remembered that improper installation can lead to fire and various problems during the further operation of the vehicle and the autonomous heater itself, as well as to the failure of individual elements of the internal combustion engine and / or Webasto.

As a result of fuel combustion, heat is generated, which heats up the coolant (antifreeze or antifreeze) of the engine cooling system. The specified coolant passes through the heater heat exchanger, which is connected to the standard engine cooling system.

The coolant is circulated thanks to a separate pump that is integrated into the heater. The pump forces the coolant to circulate in a small circle, as a result of which the engine heats up, as well as the elements of the internal combustion engine power system installed on the motor.The standalone Webasto heater is a ready-made set of all elements and parts that are required for installation. This kit includes:

heater;
electronic controller (control unit);
coolant circulation pump;
fittings for connecting to the fuel system;
fittings for connection to the cooling system circuits;
dosing pump for fuel supply;
separate heater exhaust system;
separate air intake;
mounting brackets and fasteners;
installation instructions and operating instructions;

As mentioned above, Webasto kits may differ, as they are designed for installation on different types of engines and vehicles (light gasoline and diesel cars, minibuses, trucks, special equipment, etc.). Taking into account these features, the kits differ in performance, basic characteristics and configuration.

In the process of selecting a heater for a specific car, this must be taken into account separately. For example, the installation of Webasto for a diesel engine on a gasoline car may in some cases require additional fasteners and adapters, which ultimately greatly complicates the installation.

To begin with, the installation of a Webasto heater on a gasoline and diesel unit will require free access to both the upper and lower parts of the engine compartment. At the same time, it is necessary to realize good lighting. The installation process itself involves the following steps:

The final stage can be considered the installation and connection of the battery, after which the first test start of the engine is carried out. After such a start, you need to let the motor run for XX for 5-10 minutes.
Then you should check the level of antifreeze and add coolant if necessary. Next, a trial activation of the heater is carried out and the entire functionality of the device is checked.

Finally, we add that in some cases, during the first start, the heater may not work, since there is not enough fuel in the fuel line. It will take a little time for the fuel to fill the line. After being switched on again, the autonomous preheater should start operating normally.

The installation kit for an autonomous heater for a diesel engine is practically no different from its counterpart for a gasoline internal combustion engine. As for installing Webasto on a diesel engine with your own hands, most of the operations are identical to the installation process on a gasoline engine. However, you should also take into account certain features and nuances.

First of all, it is necessary to implement the placement of pipelines from the heater to the stove lines in such a way that they are as close as possible to the fuel lines of the diesel engine power system. This approach allows more efficient heating of diesel fuel, which is especially important for engines of this type in winter. The result is an easy and safe start of the diesel engine in frosty conditions after preheating.
As for the fuel supply to the heater, a low pressure line is suitable for fuel intake. A tee must be cut into the specified line. Also, during the installation of the dosing pump, it is especially important to adhere to the recommendation that the distance from the pump to the tank is not more than 1.2 meters. This requirement must be observed without fail, since a violation can lead to unsatisfactory operation or various malfunctions during the operation of the heater.

The basic set of Webasto assumes a set with a timer. At the same time, it is worth knowing that on many cars that are equipped with a heater from the factory, the device is used as an engine heater and does not normally have a timer. In this case, the heater can be fully used and controlled by setting the timer on Webasto.

The timer is installed in the passenger compartment and makes it possible to program the preheating until the moment when the engine starts and the trip is planned (for example, 30 minutes before the driver gets into the passenger compartment and starts the internal combustion engine).

Another solution for controlling the heater is the ability to install the remote control on Webasto. The main advantages are the compactness of the control panel itself, as well as the function of turning on and off the heater remotely. In parallel, you can set the duration of the autonomous heater. Various consoles allow you to control the heater from a distance of 200-300 meters to 1 kilometer, they can have a light indicator of feedback with the heater, etc.

The disadvantages include the limited coverage area, as well as the possible loss of signal in severe frosts. Quite often, in practice, the operation of the remote control is limited only to the line-of-sight of the car. In other words, in severe frosts and in the presence of interference, in some cases it is not possible to start the autonomous heating. Note that the GSM Webasto control module is devoid of such shortcomings.

A special GSM control module Webasto allows you to organize remote control of an autonomous heater via the digital W-BUS protocol or via an analog signal using a smartphone or mobile phone. The specified module works in such a way that a sim-card of a suitable mobile operator is installed in the device and a phone number is saved from which the module will be further controlled.

Additional control of GSM modules can also be realized through the special mobile application Thermo Call. A properly selected non-standard or standard module allows starting all Webasto heaters and autonomous re-heaters, which are supported by the original Webasto Thermo Test program.

Autonomous heater Webasto. Features of air, liquid systems. Equipment and installation featuresA prerequisite for a long journey in the cold season is to maintain a comfortable temperature in the car. And here one of the optimal solutions will be the Webasto heater - an autonomous device that warms up the air in the car to the required temperature.In the article we will talk about what this device is, why it is needed, and also describe the process of self-installation of the heater.

Heating the machine with an autonomous system

To ensure a comfortable microclimate in the passenger compartment, car stoves are most often used. However, they have a significant drawback - they function only when the car's engine is in operation.

However, this is not always possible, and therefore in some situations the driver has to freeze, complaining about the wrong clothes or shoes.

An electric heater can become an alternative to the stove, however, in this case, there are nuances. And the most important thing is that the supply of electricity in a car is not infinite, and therefore it is not always possible to use up the battery charge for heating.

A familiar situation, isn't it?

The way out of this situation is autonomous car heaters. Of course, the price of such a device comes out much higher than that of a standard stove, but there are plenty of benefits from its operation.

What are these benefits?

Firstly, the autonomous heater creates a comfortable temperature in the car cab immediately after switching on.
If with the stove we would have heard from the driver the usual "Be patient, now we will start up and heat up", then in the case of an autonomous heat generator, we will not have to freeze.

Note!
Some Webasto autonomous heaters are equipped with a module that enables the system to be switched on from a mobile phone or a special remote control.
In this case, you can start heating the passenger compartment in advance, and by your arrival the car will be warm enough.

Installing the device on the bus

Secondly, the use of this device provides prestarting warm-up of the engine. Thanks to this, even in severe frost, the car starts up very quickly, and the engine resource is significantly saved.
It is also worth mentioning such advantages as maintaining the temperature in the car during long-term parking (truckers and those waiting in queues at customs will appreciate it), quick glass heating, protection from frosting and fogging, etc.

Based on these advantages, Webasto heating devices can be recommended:

Those who do not like to freeze in the car, or families who often carry small children in the car.
Those who spend a long time in traffic jams, queues, etc. First of all, these are taxi drivers, couriers, truckers, drivers of special equipment, etc.
And also for those who are trying to reduce wear on the engine of their car and maximize its efficiency.

By design, autonomous heating systems are divided into air and liquid. Air systems are the most common category of devices.

This is how an air heater works

Air autonomous heating system Webasto has the following design:

The main element is a hermetically sealed combustion chamber.
Under the action of a fuel pump, fuel is supplied to it through an automatically controlled valve with a built-in filter.
The glow plug is responsible for starting the ignition process.
The fuel-air mixture ignites and burns in a special device - a burner with a specially shaped nozzle. Air enters the burner nozzle using a special injection device, after which it passes into the heat exchanger.
In the heat exchanger, the air is heated to the required temperature, and then, under the influence of the same supercharger, it enters the passenger compartment.

The cooled air from the passenger compartment through the intake holes again enters the heater, where it heats up again.

Air heaters can be installed on almost any vehicle, the dimensions of which allow to fit the device body. The features of air models are relatively low weight (up to 7 kg), as well as low fuel consumption. For an hour of operation of the unit in the continuous heating mode, from 0.1 to 0.25 liters of fuel is burned, depending on the modification.

Liquid models of autonomous heat generating devices from Webasto differ in slightly higher fuel consumption. For an hour of operation, such an installation consumes up to a liter of fuel.

Liquid model appearance

The principle of operation of this unit is to use the resources of the engine cooling system:

Upon a signal from the user (pressing a button, triggering a timer, a signal from the remote control or telephone), the heater pump is started.
Under the influence of the pump, the pumping of the coolant begins.
Then fuel is supplied to the combustion chamber, which ignites from the glow plug and burns, transferring thermal energy through the heat exchanger to the coolant circulating through the pipes.
Thanks to this, even with a "silent" engine, the standard heating system of the car is turned on, since the heated coolant begins to transfer energy to the stove.

The process is controlled by an automatic control system. If necessary, it increases or decreases the supply of fuel to the combustion chamber, and also regulates the process of air injection into the system.

Above, we have already mentioned several times about automating the work of the system. It's time to take a closer look at what elements can be used to regulate the amount of fuel consumed and plan to maintain the temperature.

The installation can be controlled using the following devices:

Minitimer - makes it possible to program the start of warm-up for 24 hours, i.e. for a day. A standard mini-timer from Webasto has the ability to set three switch-on points, and set the operating time for each of them.

Modular timers are an improved version of the previous device. Using the modular timer, you can schedule the start of heating during the week (for example, you don't need a car on Sunday - that's why the heater won't turn on).
The remote control has the same functionality as the mini-timer.The range of the key fob is about 1 km, therefore, even being in the office, you can warm up the car at the time of the intended trip.
The GSM-module allows you to control the operation of the heater using a mobile phone.

Full-size heaters designed for trucks, buses and special equipment are certainly not worth installing on your own. But almost anyone can install a pre-heater (such as the Webasto Termo Top E) on their car with their own hands.

First you need to buy the device itself, as well as a special installation kit.

As a result, we should have in our hands:

Autonomous heater Webasto.
Gasoline pump.
Metal and plastic clamping clamps for the installation of heating system elements.
The heater control panel with a set of wires for connecting it to the car's electrical network (see also Why the owner needs a GAZelle wiring diagram).
A set of hoses and pipes.

Typically, no additional installation parts are required. In some cases, you may need to purchase a bracket to place the device itself inside the car.

In most cases, video recommendations for installing Webasto heaters can be found on the manufacturer's website.

There is also an instruction describing the basic sequence of operations:

The first thing to do is to decide on the place of installation of the device under the hood of the car. As a rule, there is not enough space between the radiator and the engine, since the pipes of the air conditioner and its compressor interfere.
It is optimal to install the device so that you can use the shortest possible gas line, as well as not too long pipes.
Then we install a stainless steel bracket in the selected place. The bracket can be painted to reduce corrosion.

Note!
When installing the heater, displacement of the fuel pipes is allowed. To do this, they must be bent to the side and fixed.

We drill holes in the bracket, to which we attach the rails of the device itself.
We mount the inlet and then install the air outlet.
We bring the gas line to the device, connect it to the gas pump. Separately, we extend the wires that provide power to the fuel pump. We also connect the wiring to the heater itself.

Photo of the connected device

We connect the heater to the cooling system through a pipe.
We bring the wires to the salon, after which we install the control panel on the panel (see also the article ZIL 130 wiring diagram: both in the snow and in the heat).

After completing all operations, we connect the supply wires to the battery and test the system. Depending on the design features, the heater can start both immediately and after a few minutes of engine operation - this is due to the presence of air in the system.

Control panel on the panel

Prelaunch heaters and Webasto heaters are devices, the convenience of which is difficult to overestimate. So if it is possible to install such a unit, then you should not save on your own comfort and vehicle resource (see also the article Wiring Kamaz: we understand the modifications).

Today I will tell you in detail how to budget for yourself diagnostics for Avnomnoki Webasto or Ebershpeher. The services take pretty round sums for this. Why not learn how to do it yourself, if you are interested. And it happens that in the city it is tough with the diagnostics of autonomous systems.

The first thing we need is some semi-straight hands that can hold a screwdriver and a soldering iron. Secondly, any K-Line adapter. In my case, such an adapter was not expensively purchased.

- 3 wires, I took a cross section of 1.5mm2 (it is possible and less, there is no load as such, I took what was) and a length of about 1.5 meters (selected individually)

Now, we need to know the identification of the ODB2 connector.

We are interested in 3 contacts, "ground", "+12" and "K-Line"

These, as we can see, are 4, 7 and 16 contacts. Here we need to solder the wires to them.

Now, we take and disassemble our adapter, disassemble it by unscrewing 4 screws

And we solder the wires to the above contacts.

Crocodiles: red plus, black earth, mom (or dad) and a body for him for "to the line".

Next, I have a Webasto Thermo Top C diesel Analog, so I will talk about it for her. (for evo-vevo, just look at their wiring diagrams.) For ebespacher, there will be The Edith program (free) and a blue-white wire (often, but you also need to check according to the diagram)

Remove connector X1, 6-pin on the boiler

The 2nd contact is responsible for diagnostics, and we attach the wiring with the dad and the body to it.

When we have everything ready, we need to download the Webasto Thermo Test program and install it on the laptop. (for eber The Edith)

When everything is ready, we connect it all ...

IMPORTANT, consistency matters! (I thought so)

We connect the wire “to the line” to the boiler.

Then, we connect the adapter power, i.e. crocodiles to mass and + 12V.

We launch the program, select our boiler from the list and voila, the program sees it and show us its errors, etc.

There is no difficulty in understanding the program, I will not describe it ...

Well, something like this. I hope someone will find this post useful ...

This is one of the rework options. you can connect the diagnostic bus of the boiler with the 7th pin of the OBD2 connector and simply connect the scanner as standard, you can make a “daddy” into the cigarette lighter instead of 2 crocodiles, and bring the diagnostic wire to the salon. here already someone has enough imagination for what and to whom it is convenient. I did just that, because it was planned to use it on different cars and it is not always necessary to run diagnostics in the car. for example, when buying a boiler, you can easily connect to it “on the knee”.

my delphi scanner reads all the boilers.pysy issue price 2-3r

there is one. reads through which program? your own or, webasto termo top? Edith?

if the boiler is not standard, also reads?

if the boiler is not standard, then you can also connect to this scanner. Recently, the Eber hair dryer scanned

and wow and delphi not regular will not see.

but through EDith and WTT did not try, on occasion I will try.

Hello. Please tell me how you WWII and Delphi were able to connect to the Ebirovsk boiler. If he is not a regular, will he be able to do it? Did you connect it through a car or somehow directly?

choose vito 638.then air conditioning and voila

hi, I didn’t use wow and delphi to diagnose a non-standard boiler. for a non-standard one, you need to use the kkl adapter and the WTT program for webasto or The Edith for the eber

HM. It was at my place that Ebert had stopped running. Can you help me? And then my hands are out of my ass. 🙁

I don’t even know what he looks like! They put it on me in the salon. Lan .. Don't worry)) I'll go to the service

Tell me the adapter model? if you can give a link to purchase, thanks in advance

At one time, I did not find a k-line industrially manufactured at an adequate price. “Inexpensively purchased” is how much?

Can you please tell me if it is possible to run vibasta if there is no remote control?

No panels were installed in the car.

there are models that are “tied” to the on-board electronics and controlled by a digital signal.

I don’t know, mercedes cl550, they asked to sell, otherwise it’s worth freezing. = /

perhaps you have a heater. This is when it turns on when the car is running to help it warm up. In any case, look for a diagnostician who has a mercedes star. Without it, you can't put your car on the shelves.

I don't know which one is there

Understood, we should try to invite local experts for diagnostics.

Maybe there is someone to help with the eber, an error pops up a power failure of the fan. But sometimes it starts after resetting the error. Brains to change or not all is lost?

In two services they said that they were probably brains, a 15k replacement. But we do not guarantee.

I then took off the eber this bullshit and checked the engine and whether the signal comes. While it was dismantled, everything worked.

Now I tried to start and the smoke comes out of the inlet pipe and does not start. Damn, and on another machine vibasta also stopped working.

I don't know why no one has yet come up with the idea of launching a lock from Chinese sticks and asking for half the cost of a flashing in bitcoins

What's the problem with buying a ready-made version? There is one electronics engineer-embedder who makes adapters for Webasto and Eber, which will work with both webasto thermo test and Edith, although he himself is located in Ukraine, sends from there, googles at once, it is not very expensive, in the region of 3-4 tr.

Where is the info about Edith? not all "webastes" as they are called webasto. Eber is still there.

In addition, for eber and a more correct connection in the Com-port settings, you need to change the standard value of 16ms latency to 1ms.

And the blue modern klines are shit. It will be more stable to find assembled according to the scheme.

give me eberspacher in my hands, I will take pictures about her in detail.

delay from 16 ms to 1 ms is not required for everyone, but yes, there is a place to be. on one of my laptops, until this is done, the program flatly refuses to see the boiler. on another laptop with Windows from the same distribution, everything works without problems.
Rightly noticed, I forgot to mention this nuance.

I also agree with the last statement. my scanner bought in 2013 is very different from the one bought by a friend in 2017, but the latter, in any case, coped with this task.

how to find out what is assembled according to this scheme in advance?

any k-line adapter is generally needed

ft232 in BL case is also expensive for cheap kline.

in ukraine, aikonss makes good kleiniks, in russia adapters from masterkit are also excellent.

one of the more or less good indicators of a passable Kline is the presence of ft232RL usually sellers indicate

ELM boiler does not "read", it is stupid physicallogical interface, it is software. But there may be fewer types of tires, depending on the chip, and the boiler can sit on an unsupported one.

Diagnostics, this is troubleshooting, you have it, read the error, it's not fucking worth it, I charge 300 rubles for it. You will have to get your pens dirty, solve puzzles and more than one, so for this they take money from you in the service.

not all such services that do not charge money for reading errors (we don’t count 300r, this is a completely normal amount). and sometimes there is no such service in the city at all.
what to do? I chose the path of learning to read errors and troubleshoot myself. thanks to this method, 2 malfunctions were identified, one was solved by replacing the air blower, the second by replacing a pair of elements in the circuit of the operation of this very blower on the brains of the boiler.

Video (click to play).

I don’t mind paying when the approach is normal. and when they scratch their turnips, they say, they probably need to change that, but we are not sure, there are no guarantees, if not it, then change another .. I think you know the prices of spare parts for boilers. and for such a diagnosis it is worth giving 2000r?
