A chap whose query started out on the forum here, but as he was not so far away, he popped his machine into us:
Well, this forum has proved to be invaluable. Machine taken to Manchestervacs and, as suspected, the clutch was at fault. Replacement fitted and other repairs carried out whilst I waited with a coffee. Extremely helpful staff, and informative too. Very, very, reasonable price for the work done. I'll definately be going there again should the need arise. Full marks.
