My 2011 A3 168,000 miles had been running rough at low speeds and idle for a week or two.
I ran two cans of Diesel Purge through it directly into the HPFP. No change in idle. I did get one low fuel rail pressure code. At the time I figured it was because I was feeding the HPFP...
heh guys im removing and replacing the HPFP on my 2010 sportwagen. I’ve gotten everything out except for the hpfp. Can’t get it to clear because of the location of the throttle body and egr. Is there any way to get the pump out without having to take the throttle body and egr off?
