Have a 2013 m5 7000 miles last 3-4 weeks the brakes have started squeaking really badly at low speed. I do drive it hard but was wondering if this was a common problem??
It could be a small stone chip stuck in the system I had one on mine and the noise it made was so loud and nasty I managed to get more attention than a 458 I was cruising with. Called BMW emergency service, a mechanic came in a van and took the chip out for me. sorted
