Why do I keep loosing the calibration on my sunroof ?
I used VCDS to program the key-fob for window/sunroof-open/close. After doing it, I used VCDS to cycle and calibrate the sunroof open and close end points.
It worked fine for several months, but now I need to hold the sunroof button to get it to work, a single press no longer works. And, the key fob no longer works (related to the sunroof calibration)
I haven't disconnected the battery, or done anything unusual. I did have my first oil change at the dealer. It seems unlikely, but would they have done something to make it loose calibration (disconnect the batter or something?)
I can re-calibrate it easy enough, just curious what the issue might be.
