Did you get this done under the HPFP extended warranty for the N63TU engine?
I'm at 74k miles, and on cold starts I get hesitation, jerkiness under 10 mph. Once it warms up no issues. Just trying to see if I go get diagnostics done again, and perhaps my HPFP needs to replaced. I had the original extended warranty replace my HPFP about 1 year ago, so looking to see if I've got a bad one and need to replace it again (and hopefully it is covered by the dealer).
