    Enabling aux heater to heat engine and passenger compartment

    Hello,

    I'm trying to disable the shut off valve of the aux heater on my 2015 VW Sharan and 2009 VW Touareg in order to enable the aux heater to preheat the engine also with the passenger compartment. I have found that it may be done by changing the value of correct adaptation channel but I have hard time trying to find instructions for the correct procedure. Could you please specify what is the correct adaptation channel number that I need alter?

    Hello,

    I'm sorry, I didn't know the software was not a legal copy, it belonged to my friend who helped me with this coding. Thank you for your help and sorry for the mistake.

    Hi,

    Hopefully this makes up my mistake, I bought a genuine HEX-V2 interface. The Sharan I got coded, it was an easy task. How ever when coding the Touareg, there is no coding helper in the VCDS so I don't know which byte and bit to alter. I try to code the aux heater without the N279 valve installed. Should this old thread with a bad start to be abandoned and should I post a new thread?

    Here is the complete autoscan.

    Verified, forum status adjusted, and released from the Hall of Shame.

    I've never played with those fuel-fired heaters because they're not offered here, but I'm fairly confident that others on your side of the pond will chime in.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Thanks to google translator I managed to figure out the coding that controls the N279 valve and succeeded. I found a German forum (http://www.touareg-freunde.de/showth...ouareg-7L-2008) and I changed the suggested Adaptation channel 4 value from 1 to 0. This morning after 20 min use of Webasto the engine coolant temp was +30 celsius while the engine oil temp was -7 celsius, so the engine pre-heat function works now.

    Thanks! The exact text may change in the future but I added this to our English file in CH 004:

    Engine Preheating
    Opening the N279 solenoid to allow the engine to preheat while the
    Auxiliary Heater is on may be possible via this Adaptation channel.

    0 = Factory Configuration (passenger compartment heated)
    1 = Engine also heated
    P.S. I have a sneaking suspicion this may also apply to #18 modules using lbls files such as 8R0-265-105.clb and 7H0-819-008.lbl .. but that's purely speculation based on Component data. I'm certainly no expert in this area - but wanted to toss that out there if someone else wants to experiment.
