I took mine in thinking it was an issue and was told the same thing. He basically said it is not a mechanical noise and its the high pressure injectors. I was there for another reason and mentioned it to them at the same time.

7200 miles on my 997.2 C2S. When the engine is initially cold, there is a definite hesitation. I've "fixed" the problem by waiting 20 secs of so and (maybe) let the high pressure fuel pump stabilize - seems to help. The car sounds like a little like a diesel on start up - not a pretty sound coming from the DFI. Everything smooths out at operating temperature
I have the exact same thing. 1/2 hesitation in the morning or when engine real cold after being parked for long time.
Had it to dealer, they kept it several days and compared it to 2 other cars with same engine and same year and ran it by Porsche NA help tech line or whatever it is called.
Exactly due to the "overrun-richness" of DFI engines.
Resolves within 30-60 seconds and runs like a devil.

Hi
I have the exact same thing.
The main hesitation in the morning. Around 2000RPM.
No fault codes, no errors, no check engine lights
My car: 911 997.1 2005 tiptronic s carrera s (Chrono Sport) 150KM.
This happens mainly in Gear #2.
It does not matter if I'm in D or M mode or "Sport mode"...
My mechanic also told me it looked normal. These engines "like" high rpm ..
Did anyone find a solution to it or leave it?
It's a little annoying traffic jams ..
