I just tried all of these codes in my 2016 A3 and had the exact same result as rajeevx5 - all but those 2 were accepted, none were the right code for AUTO HOLD adaptation. Tried them all with engine on, again with engine off.
How do we figure this out??
Hello, I did the same, with the same car/year. I´m also trying to activate the Auto Hold function. If you already did this, please post, thanks!
