I have an ARY 1.8t in my 02 A3 quattro, but think this will apply to most other 1.8t's.

The breather hose junction recently split at the camcase output on the LHS of the engine. I've changed this out for a silicone part off ebay, which is much better than the OE.

The hose that runs from the lower of the junction and across the front of the engine is now split, almost in two. Does anybody know the OE part number or even better if anybody does a silicone version.

It seems VAG make them out of chocolate!!
