    When going in to clear some long standing codes from my 2017 VW Tiguan Mk 2 4WD 2.0L diesel- I ran a new scan.
    The following new faults have appeared:

    Not sure what to tell you about the air quality sensor fault, but second fault is purely an advisory thing; it tells you that at some point the seat heaters were shut down to conserve the battery's state-of-charge.

    -Uwe-
    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 for correcting my post Uwe. I thought I could get away without the CODE thing- but it does make reading it easier!
    The Air Sensor fault is a new one that I've not seen before- so I will keep an eye on it. As for the other, it didn't occur to me to run the German error through Google Translate. It makes sense now: "Seat heating - comfort restriction due to intervention energy management".
