991.2 GTS Turbo Failure Issue
Discussion
Iknownothin said:
I had my oil lines and both turbos replaced under warranty last September at around 25k miles. The OPC were great and all dealt with in a couple of weeks. I had the standard smoking on startup and large plumes of smoke on full throttle upshifts. On test my turbos were only achieving about 0.5bar on full boost when I dropped it off with them.
I was told the replacement oil lines now have a one way valve which the originals didn't which stops oil being pulled back into the turbos on big pressure changes. The turbos are also revised and are now the same as the 992 which have additional protection around the main actuator.
I had a chat with my local Indy today (Ninemeister) as I'm getting a few bits done (Geo, clean underneath and seal with lanoguard, extra oil/filter change). I was told the replacement oil lines now have a one way valve which the originals didn't which stops oil being pulled back into the turbos on big pressure changes. The turbos are also revised and are now the same as the 992 which have additional protection around the main actuator.
If you have any info on the new oil lines then they will fit these for me as well? I suppose I could phone my OPC and see if they could help.
Interestingly, he said that the 993 and 996 turbos did have one way valves in their oil lines.

I’m really sorry to hear that you’ll be having to pay such a large amount to get your car back on the road. It seems inherently unfair when this is such an obvious issue. I sincerely hope you can get a contribution towards the costs from Porsche as a goodwill gesture.
I did actually consider not extending my warranty last November when the original 24 month Porsche Approved warranty was due to expire. I’m so relieved I did!!
The first time my car went into Porsche Solihull it was on a trailer as I had to be recovered from the Cotswolds. The car lost power, sounded like a bag of spanners and I had 4 warning lights on the dash (AWD function limited, PSM failure, Engine control fault & Oil level below minimum).
The vehicle inspection report confirmed cylinder deactivation and spark plugs needed for cylinders 2 & 6. The report also stated “oil being collected in the RH bank turbo intake” and “removing the intercooler to drain off and wash out the oil that has been drawn into the system”.
Porsche Solihull have been woeful. Zero communication unless instigated by me. Messages to call me back with updates ignored. Not the kind of service I expect from a brand like Porsche
I get the impression their workshop is overwhelmed with work. My car is due a service in May and I was advised to get it booked in last month!!
I’ll give an update on the issue when I know more.

Thanks for the message, Tim. It is unfair and wrong to be honest when there are so many people who state the same issues. With a majority of the cars being under Porsche warranty, I don't know why if they know there is a problem to be more proactive with getting it sorted out before customers have to break down out and about enjoying their cars!
I tried to get in contact with Porsche Chester on multiple occasions prior to taking it to Weissach UK, they for some reasons were not picking up the phone on that day at all so I gave up and went with the Porsche accredited route thinking that the likelihood of Porsche giving any good will out of warranty was slim even though the car had always been serviced with them, even down to the tyres during and prior to my ownership. Having had to get the car trailered to the garage, I wasn't going to get it taken to Chester afterwards to possibly have to pay to bring it back again if they weren't going to help out financially. Weissach UK has been fair with their labour costs thus far, it's the part cost that is high. The whole thing is going to cost a little under £13k (fingers crossed) as it hasn't been completed.
I also needed new rear springs as they had corroded and therefore snapped as well
I'm glad you extended the warranty! - I think this is an absolute must with these cars. Unfortunately you save at the beginning (like me) but pay for it later on. You've absolutely got peace of mind!!
It sounds like your situation is slightly different that mine, I didn't have any warnings or anything on the dashboard at all, just smoke but the car did drive although not with much boost.
Porsche Solihull sound very disappointing thus far and absolutely not what you expect from this brand!
I have heard the same rumour up here about them being overwhelmed with warranty repairs, especially from the likes of the Taycan etc.
Look forward to hearing the update when you've heard back!

It was the 991.1 GT3 rather than the .2. Rennlist will have lots of information on the web. From memory, it was American owners who got together.
My car is still going well, but I’ve anticipated the problem and have the turbo upgrade plan in my head.
Maybe you should contact PorscheclubGB in the first instance?
I've just been reading about, interesting how they managed to do it. But yes possibly have to join the PorscheClubGB to be able to find any more insights. My car is still going well, but I’ve anticipated the problem and have the turbo upgrade plan in my head.

Glad to hear yours is going well! They are amazing cars. If you don't mind me asking though why do you think the uprated turbos would affect it if it's the oil lines? Or is more changed

That is interesting. I wonder if they have revised the oil lines again since my remedial work was done. I noticed on 911 parts online that there are many revisions of the turbos so sounds like if I was on original turbos and not oil lines it wasn't fully resolved originally.

What mileage was yours on?

Basically Porsche know there is a problem to upgrade the parts and should offer the same sort of warranty terms as on the affected parts as per the 991.1 GT3
I would absolutely agree! It's just going about how to raise enough noise about it really. Porsche GB might be a good place to start, so was going to post there as well. PinkHouse said:
Looks like Porsche has become complacent with their reputation for build quality, if this was happening to this extent from a certain British supercar manufacturer, there would be a lot of abuse around reliability issues. The saving grace is that the extended Warranty is quite cheap to compensate
Think they're just hiding behind their brand a little too much. But yes if it was McLaren or Aston then we would all know about it. Ironically I decided against a the 4.0 2018+ Vantage as I thought the Porsche would be better built with no issues. But warranty is a must now I'm learning Grantstown said:

They haven’t had a reputation for good build quality since the 1990s!bosshog said:
My 991.2 S had both turbos replaced at 11k and 20k.
I wouldn’t own this gen without a warranty - it’s not expensive anyhow and for me is a no brainier on the modern cars.
As above there are updated design to try and stop it - I’ve only heard of a couple of 992 go this far so it seems to be less prone but high corrosion will effect eventually I suppose
Wow! Twice - did they mention anything after the first time about any changes or not to stop it happening at all or is it just with 992 that's properly been improved? But yes corrosions seems common on all due to the placement.I wouldn’t own this gen without a warranty - it’s not expensive anyhow and for me is a no brainier on the modern cars.

I am definitely learning always have a warranty. I purchased from an independent Porsche specialist this time around, never again if I even stick with the brand
When I enquired at Litchfield motors, the quoted cost was 9293 to have my turbos swapped out and to be refitted with GTS turbos and then to be retuned again. They said that this could go up a little if it needed new oil lines, which I think are a must, or if the bolts holding the turbos to the manifolds had seized. The power gain would have modest over my current 506bhp, so I left it for now as it’s plenty really. They do the turbos on an exchange basis. Turbos they remove are stripped and rebuilt with parts that are of a much higher standard of production.
I’m at 34K, so my clutch may go soon as mine is a manual. My next drivetrain upgrade would then be to get a lightweight flywheel when the clutch is replaced.

The first time was before I owned the car - around 2020 so perhaps before the upgrades. Second time was literally the day after I sold the car to a dealer. I had called the local OPC about it during my ownership as she like to drink oil - but they insisted it was normal. Weirdly I had the smoke on start up thing only once - about 9 months before I sold it . I don’t know for sure , but given the 992 engine is the same any replacement parts would be the upgraded lines I am definitely learning always have a warranty.

Porsche Solihull just called. They have found oil in the right hand bank turbo. Porsche have approved the replacement of both turbos, oil lines etc.Thanks for the message, Tim.

I asked how much the claim will be. They said with the replacement oil separator, oxygen sensor, new turbos and labour it’ll be £15k +.
Turbos are due in next week so I should be able to have the car back the week following.
Just renewed the warranty on my 11k miles 2018 991.2 Carrera T.
No turbo issues certainly during my ownership of the last couple of years but it seems it's a case of when not if !
I did have the other much maligned water pump failure about a year ago at around 8k miles, I read around a bit and again seems like our US chums beat the drum very hard and got Porsche to extend the warranty on that part to 10 years in the States.
Mine was obviously covered under warranty so no idea if there would have been any goodwill towards the repair this side of the pond ??
Also had a claim on the TPMS, I originally thought the batteries must have gone in the sensors but it turned out to be some rotted wiring to the sender unit or whatever it is on the body of the car ?
Anyways goes without saying the warranty is a must in my view.

I would agree that the warranty is a good idea, unless you're in the situation where you wish to make the car much better than it was at the time of delivery, in which case they'll no longer be happy to issue a warranty.
I've found the parts for the new pressure lines. Nice and cheap, but OPC suggests engine out! I suspect this is because of steel meeting aluminium and causing them to seize. I'll see what Ninemeister's opinion is on Monday. Generally they have solutions that are impossible to OPCs, who always replace everything in the most expensive way possible. And why not I guess if you get paid to do it by the warranty underwriters.

I’ve come across this as a potential easy device to decrease the risk of the issue oil building up in the turbos.

I'm wondering if I'm the only one surprised by how common the issue seems to be, pointing to a design flaw.
I wouldn't expect relatively new, expensive cars to be having such serious issues - surely the answer should be "Porsche should fix the design flaw/recall" rather than "Don't run a 991.2+ turbo car without a warranty because turbos will almost certainly go pop"?

Recall’s mean you have to admit something serious is wrong with a car and also have to be informed to shareholders if significant. Neither of which Porsche will be keen to do….never mind the logistics of all 991.2’s needing workshop time which as we know is a nightmare at most OPC’s.I wouldn't expect relatively new, expensive cars to be having such serious issues - surely the answer should be "Porsche should fix the design flaw/recall" rather than "Don't run a 991.2+ turbo car without a warranty because turbos will almost certainly go pop"?
