I have a 2001 740il. I went to BMW to replace my tranny fill plug. It was stripped. I figured I went to the best/high quality because I didn't want any mistakes. Everything went smoothly until a week later when I had my mechanic lift the car to do a tranny job.
Apparently, BMW forgot to secure the bracket holding my exhaust pipes. There were only 1 loose bolt left hanging. I took a couple of pics.
That very day (Saturday), I went to BMW to complain that I paid for an incomplete job. A manager replied the next day and I showed him the pictures. He apologizes but didn't provide a resolution.
If the exhaust pipe dropped, it would have caused massive damage to my car and they realize the gravity of their errors.
They do not take care of customers who has older BMWs. I bet if I had a new BMW, I would be taken care of....
