Hello,
2 months ago I changed the high pressure metal fuel line going to the passenger side HPFP cause I bent it while removing my IM once (oops). It drove great after replacing, and after coming back from the test drive, I let the car idle in the driveway, and after 5 minutes, it just stopped. I couldn’t get it running, it wouldnt even crank.
At this point, I thought it was the JHM tune, who, for some reason, deleted itself, so I reflashed it on the spot, and managed to get it to drive long enough (extremely roughly tho) to go back to my house (I was at a friend’s). As I pulled up, it died on me again, same thing.
At one point, the situation stabilized, and I could start it again, tho it would stall by itself the first start, and the second it would idle, tho roughly again. If I try to rev, it would choke itself, like fuel or air was missing, Pulling up the codes, there were many seemingly unrelated codes (as shown below) leading me to believe to be an electrical issue at first. But a couple days after, I found a post on this forum where a guy had almost the same exact codes as me and the same symptoms, and what resolved his issue was a new HPFP. That’s what I did, and nothing changed.
It was winter, and with my issues, I just decided to store it this winter and resolve the issue when I pull the engine this spring. But a couple days ago, something clicked, I thought about the fact the I replaced the battery a bit before everything started, but I never coded it cause I didn’t have VCDS. In the meantime I got it, so I just coded it. But again, nothing changed. Here’s the full VCDS scan after coding the battery. If some of you have any ideas, do tell, I have nothing to lose, and I do believe its a dumb problem.
(extra info: I did mess again a bit before everything started with the fuel filter since I bought a new one, but I couldnt get it off cause one of the clips broke in my hand. I did mess with the lines for a long time to try and get it off, but it was unsuccessful. Could this issue start from a small leak from or a faulty fuel filter??)
