I have a 500L that is under warranty until June 2018. The clutch pedal started squeaking when released a few months ago, at first I thought it was my shoe! I took it to the dealer and they lubricated it, no change. I took it back a second time and they lubricated another part. It's started squeaking again, albeit quietly at present. Clutch pedal working fine. I'll take it back in but surely this shouldn't keep happening? Although it's an inconvenience at least it costs me nothing at present.
