I just did the clutch on my 2.5TD over the Easter weekend. When removing the intercooler I let it drop from about 150-200mm onto a carpet. I didn't think anything of it at the time but when I came to refit it there was a great long crack about 150mm down one corner. I can't be sure I did the damage myself. I'd never noticed a crack before but that doesn't mean it wasn't there.
Anyhow, if anyone has a spare lying around they'd like to sell me I'd be very grateful.
Cheers
