Good day! I have two questions. The first is what kind of engine oil to pour in the VW T-5 2005 in winter. And the second question - I have Webasto in the cockpit, nowhere are there any buttons to somehow control (on, off), etc. How to understand when it turns on and why do I need it? Thanks for the answer! (Anatoly)

Hello Anatoly. Your question is quite relevant, so we have already prepared an answer and are ready to provide it to you.

First, let's take the time to choose a motor fluid. For Volkswagen cars, it is necessary to use only high-quality oil.

If you want to avoid problems with starting the engine in winter, we recommend that you use brands such as:

Mobile 1;
Liquid Moli;
NewLife.

Winter engine oil Liquid Moli 0W40

The only thing to note is that the viscosity grade of these consumables should be 0W40. As a rule, such a combination, if indicated on the label, allows you to start the engine even in 45-degree frost. Another important point is the purchase of an exclusively original substance. In this case, if you purchase non-original products, then, of course, there can be no question of the quality of consumables.

Video (click to play).

Webasto is an engine preheating system that allows you to start the engine even in the most severe frost. If Webasto is installed in your vehicle, then you can consider that you are very lucky.

There should not be any buttons on the system, there may be several ways to control it:

using a timer;
using the remote control;
or using the phone.

Timer for Webasto control

The timer is the least expensive way to activate the system. Look in the cabin, usually such timers are installed on the torpedo. It can be configured so that the system turns on automatically at the required time, in addition, you can also configure the running time of Webasto. Also, with a timer, you can turn on the system already being in the car.

If you have a remote, it’s even easier. Webasto turns on without problems using the remote control, if everything is configured correctly. This method is more costly, since the cost of the remote control today is about 10 thousand rubles (as opposed to 3 thousand in the case of a timer).

Well, the last option is a telephone. As you can imagine, this is the most expensive method. The software is installed on the cell, which will allow you to control the pre-heating system of the motor anywhere.

For more information on how to use the system, see the video.

On the T5 forum, they write that it is necessary to replace channel 1 with 0 in 03 channel. Tried it, the value doesn't save. Tomorrow I'll try at 042, thanks for the answers

! K, happy Birthday.

only soon will be blocked again. most likely a camera or a candle sends hello

I'm not talking about the sensor, but about the problems with the combustion chamber and candles. Do you feel the difference? due to a low fuel level, it hangs up an error and is cut off, but not blocked.

you can still decode it with a keychain, if you have it with a telestart.

I have a webasta, which does not run manually in any way, but it turns on automatically in frosty conditions, so that the engine warms up faster, so I need the salonchik to warm up too, I'm ready to splurge on a second fat battery for this))). Ideally, of course, so that you can turn on the webasta from the remote control.

I didn’t understand, it’s such a topic on t5, there are two webastas or on t4 too
I have one on t4
if I warm the interior then dviglo in dolyane))) gets warm.
finally got confused
then it turns out that 500e for webastu. for the control unit and for additional battery, and all this with the installation is somehow cheap, isn't it, I will repeat for connecting the webasta for heating the cabin with the introduction of changes to the database (i.e., when punching through the webasta's fault, it will be indicated there)

And did not try to take out the fuse for an hour, does he forget mistakes by accident? My Webasto is dumping.

at 5 it doesn’t work

if error 02 251 is blocked, then only 5052
and if it writes that the level in the fuel tank is too low, then VAG COM + comp is easily removed (if the level in the tank is less than 12 liters, then an error pops up, but the webasta starts up anyway)

The purchased module did not work at temperatures below -17 degrees. It gets a little warmer - comes to life. I also have a timer for Webasto.

1.Yes, it really is a disaster for you! And do not start without a "lace" if Webasto TTS is blocked on VW T5.
2. You yourself have not yet figured out how Webasto works on VW T5, you are already going to write recommendations. Go through the forum, read, study. The forum already has almost all the recommendations.
For me, only one thing is not clear, a person with a blocked Webasto TTS turned up, and you immediately stupidly remove, clean and repair. You disassemble, without knowing what the reason is, since you do not have equipment for diagnosing Webasto on T5. everything is clean, everything seems to be working. Put it, again it does not turn on. and at a loss why it works.
A question to you: why were they filmed and disassembled? First of all, it was necessary to figure out why it does not work? is Webasto TTS blocked? And there are several reasons for blocking, even for a working Webasto TTS heater: low battery charge, fuel level, etc.
Sorry for the owner of T5 who turned to incompetent locksmiths. I lost a lot of time, a lot of money, for withdrawing and allegedly repairing Webasto TTS, etc. Maybe, in fact, 5 minutes of the normal diagnostician's work time. and EVERYTHING worked!
Here is a recommendation for you:

Oh guys, you read you, I really want to cry 🙂

Do you know how a pre-heater / pre-heater differs from Webasto? :))))
Let me explain if someone is not in the know. preheater is a device, and Webasto is the manufacturer of these devices. So on T5 there is a webasto heater 🙂
Now tell me how to put Webasto instead of a preheater? ))))
This is not a dreary business and is fully justified.
The preheater from the preheater (PPP) is only controlled by the control. The PPP starts before starting the engine. Structurally, these are one and the same equipment.

The efficiency of modern diesel engines is very high. And when working, they emit not enough heat to heat the interior in addition to themselves. Therefore, a pre-heater was invented, which heats up the coolant in cold weather to the required temperature.

Where are your likes? We do not hesitate to put our thumbs up! 🙂 We are trying for you 😉

Hey! during diagnostics, it shows there is no connection with the heater, where to look for the problem?

Thank you guys for your cause. Very useful information.

On modern cars with a diesel engine, a standard Webasto heater is installed. The standard heater turns on after starting the engine and heats up the vehicle's coolant. It is necessary for faster engine warming up and to maintain normal temperature when the engine is idling (since modern diesel engines have a very high efficiency and warm up poorly, and in city traffic jams they can simply cool down).

Volkswagen T5 is also equipped with a standard Webasto heater. If there is a standard auxiliary heater in the cabin, there are no control systems for the device, it turns on automatically.

It is clear that the heater is triggered under certain conditions. In this regard, there are a lot of questions on the forums about at what temperature the Webasto turns on.

The temperature for turning on the Webasto is plus five degrees and below. However, in addition to the ambient temperature, there are several other factors without which Webasto will not work.

- there must be a sufficient amount of fuel in the car's tank (if the fuel level is brought to a critical level, then the webasto can be blocked);
- there are no errors in the device memory that prevent starting;
- the shutdown sensor on impact did not work;
- depending on the configuration, the ECON button is not pressed or the temperature regulator is not set to the "cold" position;
- the coolant temperature is below 69 degrees.

Naturally, the electrical system of the car itself must also be in good order, otherwise the webasto may not start, or it will work incorrectly.

It should be noted that a standard pre-heater can be equipped up to a full-fledged pre-heater at any certified Webasto center. To do this, it is sufficient to install a control system and a circulation pump.

Hello to you, too!
Three questions in the style of the USE secondary school 😉
First: what fuel does your engine and, accordingly, the heater run on?
Second: the Webasto heater model?
Third: Do blink codes appear on the display?

I don’t know, haven’t refueled yet
what is fuel?

This is not Webasto, but Eberspecher
I do not remember
I don’t know and don’t want to know

Variants of answer to question number 3:
Yes
No
no such function
yes, morse code
yes, with colored flags
we torture the unit with a soldering iron - is silent until it is recognized
after torture, the block died without confessing
what are blink codes?

Wait a minute, actually.
Complaint - the pre-heater spontaneously turns on on a muffled car (they searched for a long time why the battery was planted once a week in the morning). The interrogation showed that only the blowdown was turned on, diesel fuel was not supplied.
While they were talking, he turned on for a short time. then when he got into the car and closed the door, he turned on and did not turn off.

All to shoot and watch rot in the electronic part? Or could the reason be deeper? I haven’t done any diagnostics yet, we agreed on a later date, it’s not fast there with my hands.

I thought everything is more complicated there, i.e. more parameters are taken into account via CAN

Today I should come, but as I read it, most likely there will be water / rot on the board.

Added after 1 hour 42 minutes

Something theory and practice diverged. expected that the ECU is in the heater housing, and the bolt. somewhere in the salon.

According to the j162 scheme. but in the repair section in Elsa, everything is about the fur part, not a word about the electric one. but on the diagram it is simply indicated and the place is not indicated.

Who will tell you where this j162 hid.

Added after 2 hours 29 minutes

So I will clarify a little. the topic was incorrectly named, named from the words.

So the T5 Transporter car. but most importantly the 7HZ series. this series is not even in Elsa.

Added after 3 hours 35 minutes

Whoever has the opportunity, please divide the scheme, he himself did not cope with Elsa.
WV1ZZZ7HZH093566

I asked to punch the complete set on the part list. there beats Webasto with electronics on board, and not in the cabin.

... Elsa generally sends.

When he gave it away, the owner remembered that he had bought it (in new lard) as “special. series for Russian conditions ”. only where now to look for schemes for this special series

The wiring is standard 100%, the places of the fuses are empty, where the wires go do not understand. indiscriminately of the entire cabin

Well, I don't know, while I was looking for the right one in Elsa. all on kan were both Webasto and Thermiks. they have their own air temperature sensor, and the temperature and engine operation according to the CAN.

That's just where these wires are

There are 4 chips.
1. Circulation pump
2. Diesel fuel pump
3. And two more chips, as the turbine and the spark plug and the sensor understood.

Although now doubts began to creep into my heart, I thought that the 6-pin chip actually goes to the built-in ECU. but why then the power to the turbine and diesel pump comes from outside.

Added after 43 minutes

In vain I let the car go, had lunch, calmly read the diagram. everything is there. and the chips are all correct.
Forgive me, I won't do this anymore.
It remains to return the car, call the power supply and CAN. according to the results, open the block on the heater.

I summoned, removed, disassembled, now everything fell into place.

Now, for repair, for diagnostics, it does not come out, when the power is connected (with kan, no kan, no difference), the air turbine immediately turns on.
It is dry under the control box cover, no traces of moisture or dust. The turbine control key is not punctured. to sentence processor = heater to death? or are there bottlenecks that can still be checked? Their turbine cannot be turned on by software for cooling, for example, a camera, if the temperature sensor is buggy, and can you just ring the line for diagnostics?

If you change to a new one, then as I understand it is not necessary to buy an assembly, but is it possible to buy this spare part?
7H0 819 553 L - Heat exchanger housing with control unit? since I did not find a separate control unit at all.

Added after 1 hour 30 minutes

Collected, set. through the basic ones it starts normally, the turbine does not start itself, it slightly lifted and began to work cleanly. for now, I'll give it up. I wonder what I missed and what was the real reason.

I understand. If the air conditioner, then you also need to put a relyushka on the wind-blowing motor in the cabin.

This is what the climatic looks like:

It is easier to connect to the connector of the resistor unit for reducing the power of the passenger compartment fan motor.
Located under the glove compartment. Climb with a flashlight, the connector is easily pulled together.

Here it is, a white wire with a black stripe, this is the first speed. To it and lead a wire from the relay to turn on the fan.

Instead of a circulation pump, connect a 21W bulb and turn on the ignition. If the light comes on and goes out, then the pump is not electronically controlled, but screwed directly to the fuel pump. In this case, a relay is also needed for the pump.

The wires to the pump can be found under the driver's seat, they come out of a hole in the bottom. Brown and blue, if memory serves. But on a pit or a lift, in any case, pull the wires by 1 pin.

To access the boiler, you need to remove the bottom lining:
