Vent line for turbo on 2003 TT

[vrichmd]

I'm looking for a part number for what I believe is a vent line for the turbo charger for a 2003 Cayenne Turbo. In the Porsche parts diagram for the turbochargers, i think what i'm looking for is #25, but it says "see Group 1/03/01". Not sure what that means.

I was replacing the coolant hoses that come off the back of the coolant hoses under the manifold (the aluminum replacements were done a couple of years ago). I'm not sure if this was already broken, or if i broken when removing the manifold. Either way, it is very britle.

I've attached a couple of pictures showing the part (wide angle and closeup).

Thanks in advance for your help.

I think i may have answered my own question. I think it should be 948-107-215-52 which is pictured in the valve cover diagram. Please let me know if you agree.

As a side note, i would recommend to anyone that is replacing the coolant pipes under the manifold to go ahead and replace the three that come off the back of the engine. I had a failure with 955-106-323-50 and you still have to remove the manifold to get to them. I think they're a bigger pain than the coolant pipes, but at least they're all new now.

Thanks,

Van

Very common for that to break. I just cut off the metal compression collars from the rubber hose (which is normally hard as stone) and replace them along with a metal "T" and hose clamps.
