engine movement , help !

Hi all,

I've purchased a 55plate 1.9pdi superb, high mileage for the wife to drive.

whenever you are changing gears, and letting the clutch pedal go, i get a clunk noise.

im more than certain its the engine/gearbox mnounts that need replacing.

im not exactly sure, how many mounts there are,

and/or

which ones usually need replacing.

anyone had any issue with this problem ?

if so, how much are they ?

any help appreciated

thanks

derek
