Hi, Following a trip to Longleat, where the clutch took a bit of abuse in that I could smell it getting hot, the gear changes dont seem as smooth as before. I have just jacked the car up one side at a time and the wheels feel stiff to turn to me. On depressing the clutch they lock solid. Noy sure why. Have I stuffed the clutch and is there an inspection plug I can remove to check it? Car details, 2002 1.9 tdi, ANU engine, 6 speed box. Many thanks PT
