I currently have an issue with my fuel pump and I was wondering if the 4.2 is susceptible to the 2.0T HPFP issue where it wrecks the Cam follower and other fuel system parts ending up in a $2500 fix! Im really hoping its just a fuel pump or sensor. Thanks everyone!

Does the 2007 A6 4.2 have the timing chain issues from the 05 06 years?

From all the reading that I have done, 4.2 does not suffer from HPFP, a neglected fuel filter is a completely different story. The timing chain adjuster issues have been fixed, but the adjusting solenoids have a metal screen mesh that falls apart and clogs them. If they haven't been updated you will know. Will throw timing codes and misfire. I've replaced all four at about $80 each, two that went bad and two because I knew they would have gone bad. Takes literally 30 seconds to replace one and I think if you haven't done so, keep at least one on the car so you are not stranded anywhere when they get jammed.

My issues are nothing serious I believe my fuel pump n filter may be bad or worn out I went through a hard time n ran below half tank for two months now im stalling everytime I start the car pulling the p2293 code I believe for fuel pressure regulator perf 2 so heres to hoping its something small! I also had on spark plug changed recently to check on cylinder 2 I wonder if there is anyway that caused what is happening, but thank you very much Its my first c6 after my c5 and I love it, just want to be prepared for any future problems thank you very much!
