    How to disable automatic start of Webasto (auxilary diesel heater)

    I have same problem as many others in Finland.

    See this http://tinyurl.com/le8rvr6 and http://tinyurl.com/jwvqtn6

    Shortly:
    Diesel heater starts when engine is cold and
    when driving time is short, heater comes dirty inside > PROBLEMS!

    I read from vagarena.fi that gasoline webasto from skoda superb is possible to disable.
    Adaptation channel 06 - Additional heater functionality.

    But in Diesel is not possible? or is it?

    If it were mine, I would certainly try putting 0 into Adaptation Channel 006 to see if that produced the desired results.

    There seems to be some results were there already is 0 in adaption. Would reverse number also work. Check it out maybe?

    It's not possible to turn off the Aux-Heater in these cars. A friend of mine developed a module, which is able to suppress the additional heating (but not the timer or remote start), but his page is available in German only: http://www.bronken.de/zuheizer/ There is a construction manual on his page and the firmware for the module, if you want to build it by yourself.

    So you know Bronken. I guess Bronken is the guy who my friend is getting ideas and solutions from for his b6 to b7 passat project.

    Btw, we may not know it, but we may have walked by each other. - As usually I'm visiting Regensburg twice a year. :P hehe
    I guess you know when you have entered to Regenburg when the fog is out. Eh?

    Shortly:
    Diesel heater starts when engine is cold and
    when driving time is short, heater comes dirty inside > PROBLEMS!
    I wonder if shutting it off is a good idea? Short-trip fast-warmup is exactly what those things are for. For diesels where they come standard from the factory and (I believe) they're plumbed into the engine main coolant circuit instead of just the cabin heater core, they may have been taken into account when planning engine lubrication design along with the catalytic converters and other emissions controls. If you have a DPF, it may clog up faster. The engine may not really like running cold that long.

    If your short-trips are so short that you don't need heat, try turning your HVAC completely off. I've read on the Phaeton forum that V6/V10 TDI auxiliary heaters don't engage if the blower motor speed is zero. I don't know if that applies to all cars, but it's worth a shot.

    If your short-trips are long enough that you need heat, and you're actually getting heat, the Webasto was plenty hot.

    A032,7,1 = Activation via Engine Control Module

    I wonder if changing that from Activation via Engine Control Module (1) to Activation via Climatronic (J255) (0) is worth a shot?

    I also read from vagarena that webasto will not start if climatronic is set to OFF or LO. I will test it.
    And yes I have DPF :/

    Yes, I will test it...

    How about doing something the complete opposite?
    Could you schedule the Aux heater to let it start 10min before the driving? This might be a solution to avoid the aux heater running in short time by let it run longer?
