The F50 is in for its annual service right now. During the pre service inspection a small squeek in the clutch was noticed. Getting to the clutch is not a minor job and a day later we finally got it disassembled to find out what was going on. Turns out one of the seals has failed a a small amount of oil was getting sprayed onto the clutch plates. As a result we have decided to replace the clutch etc (while you have it apart you are better off getting everything done). Hope to have it back in a couple of weeks.
