Looked in the engine bay today of my 4 year old Golf R. Noticed that the top of the turbo is covered in some black residue? Carbon build up or oil? I’m a bit concerned as it doesn’t look right. Is it just the age of the car? Can anyone pop the bonnet on their similarly aged R and see if anything’s there?

I’ll post a picture soon.

Mine’s on 23.5k miles (3y 3m old). I’ll have a look in the morning if you like.

Yes please

Looks like a misting of oil?
-
Here you go. No residue whatsoever on mine.

Looks like yours need looking at. Is that cracking visible on yours?

Looks like oil to me looks like its coming from or above the big hose that looks like a vacuum cleaner hose connected to the back of the engine. Try taking a picture with your phone facing the back of thd engine at that point.
-
When I saw the photo I also thought it looks like cracking on the top of the turbo :sad:
-
Agreed that cracking looks serious
-
Yikes that crack looks:
1) serious
2) expensive
Definitely get it looked at because if it lets go it will be even more of a problem!
-
Thanks Boothy.
It does look like cracking you’re right but it was actually just dirt that was in the shape of a crack. It all wiped off after. It’s in for a service on a couple of weeks. I’ll get them to take a look.
No power loss. No warning lights.

This looks like oil vapour leak, which would actually make sense since right there is the PCV (positive crankcase ventilation) pipe (where the arrow points :smiley:) which is also looking covered in the same stuff.

Normally this is routed back to the inlet (after most of the oil is removed) because it has nowhere else to go, so it's not something as crucial as a boost leak, but definitely have it looked at, if anything for the mess it will make over time.

Thanks mate. Would a replacement PCV Hose fix this then? Heard the OEM ones are brittle.
-
If that was found to be the problem indeed, then clearly. Just make sure it comes from there and not from somewhere from the rest of PCV piping in that area like the turbo inlet pipe, which I find unlikely unless you were running an aftermarket one with different seals (o-rings). Some of them are not as good as the OEM in terms of sealing and they leak similar stuff as to what you have on your turbo.
