I was driving back to the office from a dental appt this afternoon, and as I pulled back into my parking lot I hear a rattling noise coming from the rear drivers exhaust side? I get out of the car, and to much surprise I see this hanging...
It looks as if the bolts that were used to hold this module in place totally rusted and snapped off! The rattling noise was coming from a metal plate that is sandwiched between the module and the bracket, which I managed to save. This metal plate was hanging by the threads of the 2 rusted bolts. My car is barely 5 months old...
It still baffles me as to why BMW doesn't use s/s or anti-corrosive bolts. I had the same problem on my E90 license plate area where the bolts eventually rusted and snapped off.
I zippy tied the damn module back onto the bracket and will be going to the dealer first thing tomorrow morning. Hopefully they replace these bolts with ones that don't rust.
