Webasto Thermo Top control unit repair service

We offer full Webasto Thermo Top heater repair service - we could exchange parts to the new or used.
We are repairing heaters from BMW, Range Rover, Rover vehicles and aftermarket heaters.
Also we do repair of electronic control units. These are always failing and giving incorrect faults.
Possible faults are:
  • metering pump interruption;
  • metering pump short circuit;
  • circulating pump interruption;
  • circulating pump short circuit;
  • temperature sensor short circuit;
  • glow plug flame monitor;
  • combustion air fan interruption;
  • combustion air fan short circuit;
  • and other...

Also it could be that it is impossible to communicate with heater (common fault for Rover heaters).


We do not repair these control units:
  • ecu with "control unit fault";
  • ecu which was flooded by water and looks completely damaged;
We do not give warranty for control unit, where corrosion can be found on PCB.

We give from one to three months limited warranty for the ecu repairs and discounts for additional non-warranty repairs if they were needed.
We are replacing not only defective parts on the PCB, but also parts which are commonly failing. Also we are correcting some hardware design bugs. Nevertheless there remains 10% fail possibility for repaired control units.

BMW E38/E39/E53/E46 Webasto heater's ecu reprogramming service

We offer BMW E38/E39/E53/E46 Webasto heater's ecu reprogramming service. After reprogramming ecu you will be able to start heater with positive signal on pin 1 (for E38/E39/E53 ecu) or negative signal on pin 3 (for E46 ecu). We do a short  test run on the bench before reprogramming to make sure that ecu is not faulty. Nevertheless it is recommended to do a longer test if you need a 95% probability that ecu is in a good condition.

Webasto heater retrofit in BMW E46 model

We could retrofit Webasto heater in BMW E46 model with ejs IHC-101 module. We managed to:
  1. enable "start heater with original remote" function;
  2. blink turn lights when remote key is pressed and heater has started;
  3. start heater with voice control button on the steering wheel;
  4. set climate control unit to defrost position and set required blower speed (currently do not work as good as expected, so it is recommended to set blower to required position before leaving vehicle);
  5. turn off park heating after configured time;
  6. heater acts as an additional heater when engine is started (requires IHKA coding and additional wiring);
  7. install everything with only one relay for climate control unit activation.
!!!!!!! Important !!!!!!!!!!!
Project was done with heater's ecu programmed to universal mode (heater is started with negative signal on pin 3 or positive signal on pin 1), because in K-BUS mode IHKA aborts heating. But we have used an ECU from E46 model: it might be, that IHKA won't interfere with E39/E38/E53 heater's ECU. It isn't tested yet.
