Turbocharger "Oil Misting"

[Mike_JS]

2020 992 Carrera (base)
I had a major service by an OPC in February but needed to take my car in for a minor issue just last week.
The dealer did their (I presume normal) inspection of the car and came back with a couple of potential problems regarding "oil misting", one at the sump plug and the other at the turbocharger.
I'm thinking that the sump plug one is just from the oil change at the service a few weeks back but I'm more concerned about the turbocharger one.
The OPC want the car for 2 days just for an investigation so even that is likely to be expensive!
I've attached a couple of pictures.
Anyone had this or can give any pointers here?

For information, I have a warranty that I purchased through MotorEasy which is supposed to include Porsche workshops, not Porsche warranty directly.

Unfortunately those photos aren’t showing much Mike, so it’s impossible to draw any conclusions from them, but if there’s oil around then most likely it does indicate leakages - however small. I would have thought that evidence of oil around the sump plug would indicate a faulty washer or an incorrectly tightened plug and that around the turbo to be seal related, but that’s just guesswork.

I’d check the T&Cs of your warranty very carefully to see what’s covered … and more importantly, what’s not covered! You could also consider getting a local reputable Porsche Independent to inspect the car which most likely will work out much cheaper than your Porsche dealer.

Good luck!

Turbo oil misting. Assuming this is the Right Hand turbo (drivers side in UK), I strongly suspect this is the same issue as I had which was picked up by an MOT tester a few weeks after car's 2Y service!

The OPC should be aware of this as there was a TSB issued in Jan 2021 which I have attached. Assuming this is the same issue it is a straight forward job. Even if the car is out of warranty, given the presence of a TSB, I would suggest this is a known manufacturing fault so should be repaired for free.

Sump plug. If that’s the result of the OPC doing an oil change it suggests they’re pretty messy Or perhaps it’s not oil but the result of cleaning off the area with brake cleaner. Is it definitely oil? Assuming it is oil, I would ask why they didn’t see this when it was serviced and whether it is possibly the result of their messy work. Also, whether they fitted a new sump plug - they should be replaced every time as they are not designed to be reused. It is possible a bit of oil is seeping past the sump plug and spreading over the honeycombed tray. When I’ve had issues like this the first step is to clean the area thoroughly with brake cleaner to remove all traces of oil and then monitor matters.

Thanks Mike, yes it is a right hand turbo and does seem to be from the right year for that problem to be a possibility.
You would have thought that an OPC would be aware of the TSB, maybe they do, at the moment they've just suggested further investigation.

With regards to the oil misting around the sump plug, it was my first thoughts too that as there was an oil change just a few weeks ago its possible just some oil from where the technician has wiped around after completing the job. I'm aware that the plug itself is replaced for any oil change, but its a possible that its a faulty seal.

Just to complicate matters for myself it is a different OPC who did the service from the one that discovered these items, different franchises too. I've decided that I should go back to the original OPC (Solihull) for investigation as they were the ones who did the original oil change, so this at least should be covered by their warranty.
I'll raise the topic of the TSB at a suitable time.
