Mk1 180 crankcase ventilation pipeworld

Tomp2000 · 2025-10-02T02:57:11-0400

I own a 2002 Mk1 TT 1.8T 180 quattro which has an engine management fault. A local garage has done an initial diagnostic which points towards crankcase ventilation pipework. On further inspection I noticed an open ended piece of hosepipe (pic attached) which is obviously not standard! I'm looking to purchase a new set of pipework but am finding it difficult to differentiate a 180 and 225 set. Is there a difference? Does anyone links or have any suggestions/recommendations?

Many thanks,

Tom

I also have a 180 Quattro, engine code AWP. This is the motor that the MkIV 1.8T GTis came with, and they were much more prevalent here than the TT. So for engine stuff, when I search, I put in an 02 GTi instead.

One of these will replace that Pardon our interruption...
But best to check the condition of the rest of it under there and if everything like the actual PCV valve is still fitted.
You can replace as is or simplify it. Not sure if the 180 is the same as the 225 but the simplified version will fit all models.

Thanks for the replies. I'm quite happy to replace the whole lot if it saves a job in the future. I've watched a YouTube video that shows removing the pipework as a whole and replacing it already assembled. Is there a link for the complete pipework set?
