Well, I just got off the phone with the dealership!
They said, my problems were due to a faulty MAF which they replaced. I have to say I'm baffled and can't find any sensible explanation how a faulty MAF sensor could have caused my symptoms! Is anybody willing to clarify this?
I mean the car sounded like it had a typical turbo leak - not that I know how the turbo leak sounds on a porsche. But, I heard a high-pitch whining sound when the RMPs climbed past 3K mark and there was no boost beyond 0.3 bar. Naturally I assumed that the passenger side turbo hose was busted (the pitch was rightward) and the passenger side turbo was spinning free. No CEL was triggered and the car was driving normally as long as I kept the RPM below 3K.
So, how could these symptoms be related for a faulty MAF sensor? Edumacate me please!
