hi my 206 diesel has developed a really anoying problem. when i try to pull away in 1st or reverse there is a bad juddering before the car moves, this happens when releasing the clutch pedal as it hits the bite, which is now right at the top travel. during normal driving the clutch is fine, until you need 1st or reverse. doesnt appear to be slipping. am i looking at a new clutch and how much to get one fitted? or is it a DIY job. i can buy a clutch kit for about £90 to £100 but worried that a garage will rip me off as i know the gearbox needs to come off.
