So I got a used power window motor off ebay and installed it today. Took out the overhead center panel to gain access to the motor. Took out the old noisy motor and installed the new one. Very simple to take out and reinstall: 2 t30 torx screws and the electric wire connector.

However, and this is now the NEW problem/issue - when you press the open button, the roof goes all the way to the back (not like before that there is around 10% left of the sunroof not going in the ceiling). When you push to close it, the sunroof will only close 80%. It wouldn't go further even if you push the close button continuously. To close it fully you have to push the TILT/raise center button BUT will sort of tilt the sunroof about 5%. The sunroof will not tilt fully like before.

I tried the sunroof button initialization procedure where you press the open button continously for 5 seconds. But still nothing happens.

Should I...

Disconnect the battery to reset everything? Is this the right way to reset all electronics on the P?

Is there any other secret programming technique to program the new motor?

I reinstalled the old one until I find a solution. Even the old one now is not aligned like it used to be. When you fully close it from tilt position it does not go 100% up but only around 95% meaning water can easily pass thru.

HELP please! :-(

 

Curious if you ended up solving this issue?

IIRC, i was told by my mechanic that if it doesnt line up, you need to get the dealership to reprogram it.

 

I have settled with the old noisy motor. I was able to re-sync the old one back on track.

When I have the time, I will try to sync it manually: open the sunroof with the old motor, turn the ignition off. Then I connect the new motor to an external battery to fully open it. Then I install the new motor. I will try to fool the system that the motor I installed is still the old one because it is open like the old motor. I hope it works. I will update the thread if it works or not.
