Just tried to explain over the phone to my local vw dealer and he couldn't work out what I was on about .
Basically I need to order a new pipe which I broke whilst doing my cambelt,
It's an agu 1999,
It's the hard y piece pipe (about 3inchs long)that runs between the expansion tank to the 90 deg rubber pipe above the alternator belt tensioner , I think the third one runs off to the turbo ,
