We are somewhat spoiled in the US in regards to consumer purchase protection laws. It is quite an uphill battle in Europe to get anything near a lemon buy back like we have in the US. A colleague of mine in Germany had an F34 4er that caught fire at around 3.5 years old....nothing from BMW. Not even a lawsuit. Insurance took care of it and that was it. In the US, the laws here would have allowed all sorts of legal repercussions for BMW.

After almost 2 years of dealing with the "heat shield like" sound that 2 dealers and a zone rep agreed was there, but Porsche's technical folks refused to look at or aknowledge was a problem, I have gotten a solution for me at least. Based on my research and disussions with several car guys, the conclusion was this was most likely exhaust system drone. My approach was to install a SOUL valved exhaust this weekend. The strange irritating noise under load at 1500-1700 rpm is now gone.
YMMV, but if you have this issue and it bugs you like it did me, switching to an aftermarket system should do the trick plus give you a great sounding exhaust system!!

I have the same problem, but no RAS/PDCC. I described it here:

Ha! We’ll I am delighted for you. I have to say that from the outset, I thought the knocking was an exhaust vs heat shield problem.

As for my car…

Porsche replaced the engine but I learned they replaced it with a ‘refurbished’ unit. It has not cured the rattle. You may recall that this was the second crate engine, the first arrived with a broken pipe that prevented fitting. I have to say that it does not fill me with confidence that the ‘refurbishment’ process is dependable. Nor can anyone tell me whether this was refurbished because of a small issue noticed during initial line assembly or refurbished following a season racing.

I approached my dealer to investigate some sort of exchange. I have to say that the process was polite but fruitless. They offered me an additional CHF10k on trade-in against a new car. In other words I have to pay CHF50k to get the car that should have been delivered in the first place.

i then approached Porsche Switzerland to see if they could support their dealer in some sort of exchange since the problems (steering wheel, C pillar covers, transmission, engine, knocking) were all there on delivery. Porsche Switzerland was downright rude - initially they treated me like and idiot, offering bland reassurances that Porsche technicians knew what they were doing, then they just ignored me.

I have to say that I am impressed with just how client agnostic this outfit is. They must have way more customers than cars because I am not getting so much as an unequivocal apology for two years of delay and aggro.

I am left with the usual two insights:
(1) don’t buy at the start of a new car cycle. (I must stop doing this 😂.)
(2) if a manufacturer/importer/dealer won’t back up its car then don’t buy from them again. (At least I don’t do this.)

and a third one:
(3) don’t buy a Porsche in Switzerland.

So, I am pleased to say that I am looking at new cars again (always fun). Not so happy to say that I am getting punished on trade-in because the dealers are unsure of the value of a car with a non-original engine and my service log has a big sticker in it declaring the fact as if it were a value adding feature, but I am not giving any more money to Porsche CH. I’d rather take the trade-in hit and find an outfit that is trustworthy.

Coming back to this two years later because I seem to be having similar issues in my GT3 - did you ever get your issues resolved @BIGWORM ?

Meh! Not really. They replaced the engine and the gearbox, and I suspect that in the process they re-sited the exhaust a little better. As a result, the bogged down rattle is less frequent but it still happens. The gearbox still panics every now and then too, which is always exciting! Solution seems to be to keep the revs up to avoid the bogging. Manual mode also operates reliably.

On the whole, an entirely disappointing ownership experience in my eyes. Never had anything like this with the 991 or 997 series, or any other car actually. I still have the car, although it will be gone by August when I move Stateside. My long term reflection is that for mere mortals - as distinct from the racing gods - peak 911 for build quality and performance was the 991 series.

I'll not buy another new Porsche now. I believe they are overextending their profit margin and shortchanging their sports car customers. Too much plastic. Too many reliability issues. Much like Mercedes in the early 2000s. I have however taken a sizeable shareholding in the recently floated company. I feel confident that that will prove out.

I did. I asked them to buy it back and they did. Both of my 2020 992's where buy backs. So I went back to BMW and purchased a G80 M3 comp X drive. Its ugly. But its a very very nice daily driver. I do miss owning a 911 though.
