Wifes car is coming up for end of three year warranty/MOT at the end of March. Its only done 16000 miles !

I'm a little concerned about the clutch. The biting point has always been at the end of the pedal's travel, and there has always been a little clutch judder from new too.

I've mentioned it to the dealers when its been in for servicing/warranty work (not much) but they can't see anything wrong.

it mainly does it when cold, but can then disappear for miles. I wouldn't mind if it was there all the time, but its intermittent.

Do I need to worry ?
