I have just purchased a '55' plate 2005 307 S. When I lift the clutch up slowly (with enough revs of course!) to pull away in first gear or when I am reversing into a parking space the clutch feels very juddery. Gear changes up from 2nd through to 5th are fine, but when I change down from 3rd to 2nd, the juddering effect comes back. Are there some reasonably simple checks and adjustments I can make to the clutch, or is it a replacement clutch at the garage time? Cheers guys.
