When was your car born? I'm wondering if this can be narrowed down to a specific time range...As above. When I turn right in my MCS my clutch goes spongy and then won't come all the way back up. Showed this to the dealer who investigated and said that the crankshaft is moving and affecting the operation of the clutch when I turn right. New engine needed! My dealer has two cars in at the moment with the same issue.
That and the jumping out of first gear issue (fixed with a new gear selector switch) means the start of MCS ownership has been a bit rubbish!
Still mostly enjoying the car though!
edit: sorry just seen there is a thread about this in the main forum! Sorry.
