    Im guessing your cars a diesel? If its is, the timer settings are via the MMI, (something like aux ventalation / heating - I am not in my car at present, but it is there) just set the time a short while before you are due to get in and leave, but it can kill the battery, hence I dont use it.

    On the VW phaeton its a small one cylinder desel engine that just warms up the coolant to the cabin. On frosty mornings you still need to remember the engine coolant is cold and dont give it beans!

    Can be activated in the mmi or via vcds, one of those features that do not always come activated from the factory.

    Unless its spec'd at build, it wont be fitted, so coding wont be of use, mostly fitted in Nordic countries.

    re-programming the Phaeton “auxilliary heater” to work as a “parking heater”


    1. Module 18 security access code 22106

    2. Adapt channel 09 to value 2
    3. Adapt channel 04 to value 0
    4. If the heater locks up, clear the error by adapting channel 03 to value 1
