Hello again. Today, as promised, as well as by popular demand, we will talk about a useful, but very capricious device called Vebasto (Webasto))) he is also a liquid autonomous heater, he is a diesel heater, he is a coolant heater, he is pre-heating system ... in general, he's Gosha, he's Goga, he's Georgy Petrovich.)))) ... although NO - Petrovich, it's I.))))
Video (click to play).
To begin with, briefly about the principles (very principled) of its work and usefulness for the car:
1. The basis of Webasta is a combustion chamber (boiler) made of an aluminum alloy into which the electric fan pumps air (we hear a hum during start-up), the glow plug is pre-heated, and then a special pump pumps fuel from the tank (we hear silks under the bottom of the car near the tank ). A combustion (flame) is formed inside the boiler, which is controlled through the glow plug, based on the indicators of its resistance (changing from heating), when the boiler is hot enough, the glow plug turns off (saves battery energy) and ignition occurs due to the heated walls of the boiler (we hear weak aircraft hum and we can observe the exhaust from under the right front mudguard).
Here she is hiding ...
The fuel mixture ceases to be supplied to the combustion chamber when the coolant temperature approaches 85 degrees and Webasta turns off.
2. At low temperatures, its uninterrupted operation is extremely important for facilitating the start of a diesel internal combustion engine and maintaining its required temperature regime. It should be remembered that 75% of the ICE wear occurs during cold starts, therefore, preheating the diesel ICE cooling system not only makes it easier to start the ICE, but also increases its resource. Those. This Webasta is a very useful piece for internal combustion engines.
Now let's move on to her capricious qualities and the rider of her work.
1. To start the heater, the coolant temperature should not be higher than 40 ° С, and the outside air temperature should not be higher than 4-8 ° С. If it is warmer outside or the car has not yet cooled down, Webasta will not start.
2. The peculiarity of Webasta is that when the level of diesel fuel in the tank is low (less than a quarter), the system blocks the operation of the stove (that's an infection).When filling the tank, the Webasta system is not unlocked! (exactly an infection), in this regard, the connection of diagnostic (dealer or SDD) equipment is required to unlock. Therefore, do not bring the fuel level in the tank before the indicator lights up at low temperatures!
3. Also, Webasta is very sensitive to the level of coolant. As a rule, after trying to start Webasta, the electric pump starts to drive the coolant and the level in the tank drops, Webasta does not start. ... The corresponding inscription lights up, you add coolant, but the re-heater is not reanimated. Most likely, in this case, you need to look at pp. 2. Again this bitch was capricious.
4. Light whims (errors) can be reset by removing the 32nd fuse (20 A) under the hood according to the following scheme: (removed the fuse for 3 seconds, inserted it, pressed the start, started the car, waited 3 seconds (you can press the ON button on the remote control instead of starting ), again removed the fuse for 3 seconds, inserted). But to be honest it rarely helps.)))
There are several reasons for Webasta's malfunctions, the main one is software blocking, it can be eliminated, as we said above, through diagnostic equipment without mechanical intervention. In addition, a common cause of Webasta's malfunction is clogging of a candle, clogging of a nozzle, burners in general, everything inside, accompanied by increased smoke (smoke comes from under the wheel as if the car is on fire, it often happens at the first start after a long break. Well, the worst thing is ... destruction of the boiler, only its replacement will help.
Now to the control of Webasta and decryption of blinking on the remote control. If there is no remote control, then Webasta is turned on automatically when the engine is started, according to the ambient conditions and coolant temperature. But in most cars, Webasta is equipped with a remote start. The remote control is of 2 types, the scheme of work is the same for them, the differences are only in size and shape. The operating range with a good battery, according to the manufacturers' assurances, is 100 m, and it is not necessary to point the remote control at the car. In practice, the line of sight of the car is much less and desirable ... How can it be controlled?
1. To turn on the heater - press and hold the ON button on the remote control for about 2 seconds. The green indicator will light up and go out, which means Webasta has turned on and the signal has passed. Warming up will work for 30 minutes or until the coolant temperature reaches 75 C, or if the fuel level falls below the minimum or the battery is discharged.
2. If Webasta failed to start, the indicator will blink 3 times and turn off.
3. To turn off Webasta yourself, press and hold the OFF button for 2 seconds. The red indicator will light up for about 2 seconds, Webasta will turn off. Everything is extremely simple ON (hold) turn on, OFF (hold) turn off ...
BUT there are secrets and decryptions in the blinking LEDs on the remote.
1. Green lights up for about 2 seconds. - the heater has turned on.
2. Red lights up for about 2 seconds, - the heater has turned off.
3. Blinking alternately green and red for 2 seconds - no signal from Webasta.
4. Lights up orange for 2 seconds, then changes to red - low battery charge.
5. Blinking orange for about 5 seconds - weak signal, you need to change the battery in the remote control.
In the next part I will try to tell and describe the procedure for unlocking Webasta on my own using the K-Line adapter, which can now be ordered on Ali for 300-600 rubles. In general, that's all, if you missed something, write. Well, traditionally vidosik.)))
Diesel Freelander 2 are equipped with a Webasto heater that runs on diesel fuel. Installation on all cars for the Russian Federation is due to the fact that in Russia the winter is quite long and harsh, and the additional unit allows you to warm up the engine faster and get additional comfort when operating the said vehicle. It is thanks to Webasto that the motor functions in the cold season as well as in summer. All motorists know that rubbing elements wear out exactly when it's cold outside.The heating element makes it possible to significantly increase the service life of one of the most important components in the machine - the engine. Also, thanks to Webasto, a comfortable temperature is maintained in the cabin.
If you want to turn off Webasto while the engine is running (not yet warmed up, and the ambient temperature is below five degrees Celsius), you will not be able to do this. The engineering design of the unit does not provide for this. The automatic control maintains the temperature constantly and works reliably.
But even this system is not capable of functioning forever, therefore it periodically requires replacement. In the LR King car service, you can carry out Webasto repairs at a convenient time for a reasonable price. We specialize in just such cars, so we do our job at the highest possible level.
A parking heater usually has two problems. It may not start at all or be blocked. In the first case, the problem is a malfunction of the burner of the unit.
In the second - in the blocking of the system, which occurs due to the low level of fuel in the tank. This approach is necessary to comply with fire safety measures and to save fuel, which is already scarce. Of course, the system can be unlocked, but this will require special dealer equipment required for diagnostics. You can come to us and carry out a check in a short period. After that we will do a test run. If this does not work, we recommend disassembling and dismantling the Webasto on Freelander 2. As a rule, the problem lies in the burner or candle, they are deformed, get too hot and are covered with soot due to the use of a low-grade diesel engine. The burner cannot be repaired; it can only be replaced with a new part.
Under the wheel arch liner, namely in the front wheel well, there is the heater itself. In order to change its burner, you need to remove the unit. In addition, you will need several seals, they are sold as a kit. Very often it is necessary to drill out the fastening bolts, due to the fact that they sour and do not loosen. After replacing the part, the heat exchanger is mounted in its place. Do not forget to add coolant after handling. This is necessary for pumping the system.
We strongly advise against repairing the boiler yourself. Entrust this business to specialists who have approvals, the necessary certificates and experience. Otherwise, you risk starting a fire, damaging your car and getting hurt yourself. It is important that our car service is specialized, we specialize in Land Rovers and provide a guarantee for our work. You don't need to buy anything to complete the renovation. We will do the work on a turnkey basis using original parts. If necessary, we will advise you to install additional elements in order for the stove to function properly.

Webasto did not work either from the remote control or with the engine running. We carried out diagnostics. Error codes: B1 D33 “Interruption of ignition during normal operation”. As I understood by the master, it is blocked because the burner, the burner does not ignite. The diagnosis is to change the burner. Is it so?
In this article we will tell you about the additional heater on Webasto fuel on one of the most popular Land Rover car models - Freelander 2. Cars before 2012 and from 2013 have a slight difference in the heater design.
For reference: Webasto is the name of the manufacturer. And the heating device itself is correctly called "additional fuel-fired heater". In the common people it has taken root - Webasto.
There are two modes of operation for the Webasto auxiliary heater on Freelander 2 vehicles.
The first and the main one is in diesel engine re-heater mode... The heater starts to automatically turn on and work when the engine is running and the outside air temperature is below +5 o C.
This mode was invented by engineers in order to warm up a diesel engine, which heats up longer than a gasoline engine. The diesel engine needs reheating because at temperatures below -15 o C the diesel engine may not reach operating temperature. Also, heating in the passenger compartment will be ineffective, it will be cool in the passenger compartment.
Here she is hiding ...
