I seemed to have developed a slight judder in my clutch, here are the car/symptoms: 1.9 tdi afn avant,110 bhp (re_mapped) 232k miles. New Sachs/luk clutch and dmf fitted 40k (18 months) ago When cold like pulling away from work in the evening I get a bit of a judder from the clutch when moving off. This only happens when cold and only on the 1st pull away. There appear to be no other symptoms, and the clutch is not slipping. There is a new oil leak which appears to be coming from the back of the block which I'm guessing could point to rear crank seal, I'm assuming that the oil is leaking onto the clutch and it's going to be a box out job to fix. Does this seem reasonable diagnosis for the symptoms? Mechanics diagnosis on the phone was more likely to be the dmf giving up the ghost. Any thoughts on what might be going on.
