i have a problem with the electric window in my car, when i took of the doorcard and weather shield i could see that the teeth were worn so i went about getting another mechanism ( 10 quid from scrappy ). But when i looked in my Haynes manual it says that this job should be carried out by a BMW specialists as they have to do a lot of calibration so the glass doesnt hit the boby etc
Is this true? Or can i just swap it over myself
PS. They said only the coupes have the problem not the 4 doors.
