991.2 GTS 22000 miles
mine is currently having its drivers side turbo replaced. Was smoking periodically on start up but then lost all of its oil when redlining in 3rd. Being changed under warranty 
what are peoples thoughts on not changing both turbos? They claim nothing wrong with the other but it feels inevitable that it will go in time. I havent bought the car to cruise round in, who does?! 

are the replacement turbo and feed lines an upgrade or the same oem parts ?
The amount being changed is a bit of a joke for a precision German sports car, I still love It but I don’t trust it !

Hi JCT911,
Meeting many people through the club who have had their 991.2 turbo's or a single turbo replaced under warranty.
Do you know if the new fitted parts are re-engineered to last?

Had both my turbos replaced last month at 73,000(ish) miles on my 2016 C2S. Not smoking but the wastegates were sticking so both turbos and oil lines were replaced (along with a whole host of other bits), just another potential failure point to be aware of!

My car (gen2 gts) at 16k had smokey exhaust…initially OPC replaced turbo oil drain pots and pipework. First drive back in car ,bit of revs and huge plume of smoke so straight back to OPC…new turbo fitted to drivers side. They explained the turbo oil drain pots and associated pipework was Porsche’s first fix “package” when cars reported as smoking. Pretty frustrating as turbo failure in this model is not uncommon but garage was adamant the “package” was the fix….which it wasn’t and car needed duplicated work to  fit new turbo. Had the car back for a month now and it’s started smoking again. I suspect the other turbo..the one that was deemed “all good” when I seriously questioned at the time of repair. As my car now has the new drain pots/pipework hope not too much hassle getting second turbo replaced. ….all work done under OPC warranty.

Although both my Turbos were replaced (and it sounds like it was one of the early incidents, when I had plumes of smoke being emitted), I am not sure that they were root cause of the problem. There was certainly oil leaking from the pipes and connections, which subsequently got into the turbo/s, damaging them. Prevention may have been possible, previous to the incident, without changing the turbos.
However, it does seem that Porsche is tighter on warranty claims than it used to be, possibly in the interest of profitability rather than customer service.

Just had both my turbos replaced under warranty by Porsche Silverstone. Can't praise Silverstone enough they were great. They also changed the oil and changed the plugs also. The car had just covered 31,000 miles.
