Niello BMW of sacramento checked my Z3 2000 for traction control light is on advise, and some fluttering noise came out during acceleration. They found out that there's metal shavings in the differential. They repaired it and replaced it with new one as what they advised to me, plus they replaced thr brake pads, rotors, sensor drive belts, cover air bag and that cost $3200.18 which I paid. I questioned them if that's still be covered by the warranty since I bought that car in May 1999, and they said, " no it's not under warranty." So I paid the whole amount of $3200.18. So I drove my car and in a matter of days the car broke again, stopping in the middle of freeway, and that time I heard some fluttering noise again underneath, which scared me. So I immediately called some help and took my car to niello BMW in sacramento for repair and it them a week to repair my car. After it was being repaired I traded it in with Lexus rx 330 in roseville since I'm scared already driving BMW and don't trust that car again.
