Hey everyone, I have a 2009 mk6 GTi which I was selling, took a deposit and then it cutout two days later. Initially gave me no codes, just wouldn't boost properly and misfired on all 4 cylinders at once before I limped it home. Brought it into town that night for fresh fuel and fuel filter, on the way home it went fully limp and threw a code for p2293 fuel pressure regulator.
I messed around for a few weeks replacing a used fuel pump, found torn pcv and replaced it also with new. Still no luck. Brought it to a mechanic and all he could get was a fuel pressure issue, with none of the sensor readings looking out of the ordinary. He suggested a new fuel pump so bought brand new genuine pump and follower, and fixed original pcv but the noise and cutout still persist.
I'm at my wit's end and hoping someone has experienced something similar as the mechanics only suggestion is that it may be internal and I'll have to start stripping the engine to investigate (meaning a used engine would be more cost efficient unless I take it home and do it myself).
See attached video for the noise. Given the symptoms, I would've thought it was an air issue rather than fuel...
