Mine is in for seat rail replacement today. I've been living with this problem for a while, but I mentioned it to my SA the last time I was in for service, and they checked it out and confirmed "broken seat rail" - but had to order the assembly first - it took a week for it to come in. They also said that it would be about a 4 hour install. Warrantee service, and I have a E90 328loaner for the day. Just in time too- got a HPDE at the track this weekend !
