    But where do I go from here?

    Tried from 0000001 to 0000400

    ECU only accepts 13377 to activate ACC.
    If your engine doens't accept FTS option, only ACC option, check if you have any FTS option active and disable it.

    Ok, because when i try to calibrate ACC the values never Changes (front -4 and rear 8), so my guess was that the sensors for xenon could have something to do with it.
    When I calibrate ACC, it shows calibration OK..

    The FTS in ACC adaption is not even an option since I downgraded.
    ACC adaption 5 (adaption after calibration) says "NOT OK"...
    If that could trigger DTC in ECU and not ACC?
