Hi Alex, when the car came from Canada to Germany and I came to pick it up battery was empty and tailgate window was down and roof oped. Guys helped me start the car. First I pushed overhead buttons to close roof and window, does not work. I tried with key cylinder, I closed roof and window but when I started car Window went down and since that stays down.
All parts are still same did not replaced.
I checked, cleaned and lubricated all contacts and latches.
Now the window goes down when I press the yellow button on the tailgate or I connect to the window motor but it never goes up.
I cannot relearn because the window stays always down, I can only push it up with my hands.
As I understand, empty battery has caused the problem.
Thanks for helping.
