There are two sensors, the outside temperature is under the bumper, the coolant is on the brains of the Webasto.
I keep my mouth shut myself. They'll crap the same. And the first will be garage specialists with an indicator screwdriver. And the ebers have to be repaired.

This, as I understand it, is for those who have a lace. I went to read about Wag-Kom.
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

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.

What and how can be done on one's own when repairing a wet Webasto stove?
First of all, you should measure your capabilities and experience with the complexity of the task. Therefore - decide whether the task at hand is up to the task. More than 50% of all heaters that get into the repair went through the hands of the owners. Many of them were initially with trifling breakdowns, or were simply blocked by software and did not require mechanical intervention. However, after the repair of the owners, we also had the opportunity to earn money. Do not be among such "repairmen", if in doubt, just carry / take the heater to the service station. Moreover, the failure of the heater may not be caused by the heater itself, but by the associated vehicle systems.
And, if all the same decided on an independent repair - then go ahead.
Let's start with the simplest checks. If the heater stops working in cold weather, then most likely the matter is in the fuel supply system, or rather in the fuel itself. (more information about fuel and its composition can be found in the article). In this case, the check must be carried out in a warm garage in order to exclude the influence of the "summer" solarium on the work of Webasto. It should be noted that similar problems appear even at temperatures of minus 15-18 degrees. You can also connect power from a separate container at the time of the test with a known clean and good winter diesel fuel. In any case, the fuel supply system should be purged and cleaned, the fuel filter should be replaced, and if there is none, put it on.
An indirect sign of the lack of fuel in the power system is the sound of the metering pump. By the way, it must be installed correctly,
If the sound is loud and loud, then perhaps diesel fuel does not enter the fuel pump itself. With "good, correct" operation, the sound is muffled and low. The reason may be a leak in the fuel line, air leaks.
You can check the integrity of the winding itself with an ohmmeter. The winding resistance at 20 degrees should be about 136-154 ohms.The operation of the valve can be checked by applying to it short pulses with an amplitude of about 8-11 volts with a frequency of 0.5-1 hertz. At the same time, flushing fluid, such as carburetor cleaner, is supplied to the tube. Sometimes such a check operation is enough to bring the heater itself to life, if the reason for the refusal was a blockage in the fuel line at the installation site of the solenoid valve.
The next stage of verification is the electrical part. First of all, you should make sure that the F1-F3 fuses are working properly.
Check the presence of supply voltages on the timer (connector X8). If the power comes to the timer, and the last one is "no mu-mu", then there is a reason in it. How to start Webasto without it is described below.
If the heater was factory installed with a CAN bus connection, check ALL literally fuses. Firstly, it will take a little time, and secondly, make sure once again that they are in order, and thirdly, it is not possible to specify a specific fuse for all possible variants of car modifications, even within the same model, well, and fourthly - the operation of the heater also depends on the state of the sensors that are not part of it. For example, from the fuel level sensor, from the outside and interior air sensor, from the collision sensor, from the voltage of the on-board network.
Separately, you should check the power supply at the connectors of the stove itself (X1-X2) - plus and minus and the quality of the contacts. Often, in the most inaccessible places, almost in the plug itself, the wire breaks off or rotates, while the insulation is not externally damaged.
If both power circuits - fuel and electrical - are normal, then the heater can simply be blocked as a result of past errors that have already been eliminated, but are still recorded in the memory of the heater control unit.
The heater can be unlocked in three, now forgotten ways:
3. Unlocking on the recommendation of the manufacturer Webasto. Unfortunately, it does not always work, but nevertheless, there is a chance.
step 1 remove power from the heater control unit for 3 seconds.
step 2 supply power and turn on the heater using timer 1533 or remote control.
step 3 after 3 seconds, turn off the power supply to the heater control unit again
Step 4 After 3 seconds, apply power to the heater control unit.
Judging by the Webasto manuals, everything should work, and, by the way, it often works.
It is checked with an ohmmeter at a temperature of 25 degrees. Resistance of a serviceable element 0.2-0.4 Ohm
It is checked by applying a pulse voltage with an amplitude of 10-12 volts and a frequency of 1-10 Hertz. The resistance of a serviceable pump is 5.2 Ohm at a temperature of 20 degrees. A serviceable pump should provide a volumetric supply of fuel in the amount of 36-45 grams for 3 minutes at a pump activation frequency of 7 Hertz.
It is checked with an ohmmeter at a temperature of 24 degrees. Resistance of a serviceable element is 2-4 Ohm with a complete set No. 1. Resistance of a serviceable element 0.8-1 Ohm with a complete set No. 2
Should work when 12 volts are applied to it. The resistance of a serviceable element is of the order of 10 kOhm. However, you should focus precisely on connecting the power directly.
At 20 degrees, the resistance of the element is 2-4 Ohms.
Overheating sensor
At 20 degrees, the element resistance is 240 ohms.
Resistance of a serviceable element 136-154 Ohm at 20 degrees
