When I first start the car up and let it idle, there's a running/grinding sound which disappears when I put the clutch in. Doesn't seem to happen when the engines warm. Any ideas?

How much do you reckon that'd be to sort out?

I'd put up with it, which Fabia have you got?

MK1 vrs with 85k on it. Is it sound to leave, won't cause any other issues if left will it?

Nope, just checking gearbox oil level will tell you if the seals leaking yet.

I didn't do this and just drove on - ended up with a broken box and taking the centre out of the clutch plate !! I could have saved myself 2 weeks and about €1000 ! 

I'm probably going to take it down to the garage to have a look at it anyway.
