Hey guys, first post. Been having some issues I've been trying to track down in between my busy schedule. Little background, purchased my VW with 67k miles and it now has 183k miles. I drive a lot, mostly highways and commutes. Car has been flawless, up until a couple weeks ago.
My car has been having a hard time starting and staying on. It progressively got worse until I was able to leave it at my mechanics shop. Received some fueling codes relating to the fuel pressure regulator valve (N276). Here is the auto-scan of the engine module prior to some repairs:
The radiator fans are a different story. I'll have to get to those another day.
Anyway, had the mechanic next to my shop replace the thrust sensor, since the dealership service writer (a friend of my brothers and I) suggested that sometimes it's this sensor that goes bad and not the fuel pump. After this didn't cure the issue, I ordered a new high pressure fuel pump. After this was replaced, we got a little better.
When receiving my old fuel pump, I was informed that they replaced the spark plugs. I didn't know what type they were so I went home and replaced all the spark plugs and coil packs with new ones I purchased previously. My old spark plugs were very very black probably due to the car running rich.
Prior to getting the car home, it would start up very rough like, but I was able to give it some gas and get it going. After driving it for one minute, it would even out and the car would run just fine. Even coming to a stop, it would idle as it normally would. When getting it home, I went ahead and pulled all the plugs and coils, replacing them with new NGK laser iridium plugs and Denso coils from FCPEuro. When starting the car up to move from garage to driveway, it fired up perfectly. I think this was due to it being warm.
This morning comes around and I start the car to get to work. It starts up rough like again and I slowly get it out of my driveway and it solves itself out again and drives normally. I get myself to work just fine where I scan the car again. Here is the engine module scanned again:
I did some scanning during lunch to monitor a few blocks. Not exactly sure what to look for but I noticed that I was able to get misfires on 2, 4 and 6 while in park and upwards of 4-5k RPM's.
Possible ideas that my buddies and I have thought of could be:
Carbon cleaning needed
Injectors need to be cleaned
Kinked fuel pressure line that flows fine when warm/pressurized
With the information above, what do you guys believe I should be doing? If you guys have any need for certain engine measurement blocks to be monitored/posted, please let me know what to do. Thank you all for getting through my first post!
