Hi All,
I just changed the battery on my 2k A6 4.2Q and noticed a few things stopped working. The sunroof does not open anymore, the radio says "SAFE" (guess it needs a code). I ran the vag-com and also noticed a bunch of other items showing up now. Fyi, I changed the both S1 02 sensors recently and am seeing the fault codes re-appear. Not sure why. Any thoughts on what I should do to fix them? Do I need to reset the computer? If so, how? Apologies for the long thread.

One thing I would like to add is that when I start it up, it idles rough for a minute and then seems to idle more smoothly for some reason like it corrects itself. It happens every time I start it no matter how many times I do. Not sure why that happens.

Clear all "along with the old dated" codes, enter your radio code, drive the car as usual.
After a few days check vagcom for codes aside from your possible door switch acting up like just about everyone else "super cold temps" you should be OK.

Report back.

Just to clarify; Old dated codes are codes from the past but maybe you check your codes often or at the time of a repair.
