OIL LEAK! pipe near turbo or diverter valve??

[R32UK]

DV failure is very common... esp with modded cars. Relatively cheap to change and should be covered under warranty anyway

Snoopy - did you get this sorted? I think mine is leaking in the same place.

No sadly not yet, ive been extremely busy at work (overseas problems) and had high priority family buisness I've had to sort. The GTI has been parked in my garage ever since I spotted this issue and not moved since. I've been using my late fathers old car when needed.

I'm 90% sure mine is a PCV valve failure. (Positive crankcase ventilation) Take the engine cover off under the bonnet it just pulls off and see if the small tinfoil covered pipe from the PCV system when it goes into the large air pipe has oil on the join. Mine does.

I also have symptoms of DV diaphragm tear imo but I've had them for a long while before the oil leak.  Dealer was suppose to check for that back in march at service.

Had a word with a vw expert fitter at a vw dealership and he did NOT fill me with confidence he did not know what I was talking about and said they would just change the turbo if it went there.

Just checked my car and it does have oil on that pipe. I took the car to the garage about 2 months ago to have this investigated but they couldn't trace the leak. They cleaned it up and told me to come back if it happened again. The car is booked in to VW Swindon in a week so at least i can point them in the right direction. The oil leaks down the back of the engine and leaves a couple of drips on the drive. Also tried running the car with the oil cap off and it makes no difference to the running. Sounds like it is the PCV.

I'm going to do a little write up of symptoms and photos of mine for when I take it in and hope it does not offend their technicians.
Seems some dealers don't know much about this engine and how it works.
I'm also going to try a different dealer and pray they have more clue and take care unlike my previous dealer.

I do need to get my ass into gear as its 4 months now but priorities and just not had the time or been here.


let me know what they find with yours please.
Thanks.

So to recap,

OIL HERE --- Under the car on the turbos diverter valve seal/join ---  06F 145 710G



OIL HERE --- Main air feed pipe join down the side of the engine.



OIL HERE --- Small pipe join connection to air feed pipe.



Above small pipe is connected to this --- 06H 103 22A A  --- 06H 103 495 E





And that is this

Just got mine back from the dealer having had exactly this same issue fixed under warranty. When I spoke to them they advised that they'd changed a hose, some seals and an oil feed pipe(?).

At first they were just going to change the seals and hose but then found a pipe underneath that was leaking that they hadn't spotted originally. (sorry, don't know which one)

Hope that solves it, will keep an eye on it just incase.

Thats sounds like maybe your oil leak was caused by the high pressure oil feed pipe to the turbo. I was told about a few of those failing.

[R32UK]

have you noticed any excess oil being used and extra smoke out of the back on full kickdown snoopy?

[Snoopy]

Not using oil and no smoke.
