That bloody cow bell noise is the passenger break guard. I used my trusty poking device 'old billiard cue' and pushed it back away from the disc quite firmly. I found with mine in particular, it was pinging off the disc at about 5 o'clock, i.e third the way round clockwise. I got the Mrs to drive on idle, backwards and forwards in an empty quiet car park and i spotted the problem straight away.
Solved. Was driving me nuts. A new M3 that sounds like it has a knackered exhaust.
I'm confident that will solve the pain for many of you. Actually glad, so many people had the same problem and i wasn't alone as BMW were no help at all. Can't replicate..........the norm.
OMG i heard this goddam sound today while at a stoplight windows down and no cars next to me. quiet street....so what is the issue and how to fix it? any pictures or detailed descriptions?
is the above really the cause? how does it happen?
