  1. Alright guys I just want to make a place here for people to post their codes for all to see and possibly help if they've come across them before. Sound like a good idea?
     
  2. i like it ... wana start with one of mine ? haha

    2F7E - UNKNOWN DESCRIPTION via jb4 and mhd shows NO CODES!
     
  3. I also have one. Shadow code: 2FDB fuel high pressure nach freigabe der Einspritzung

    It shows up once in a while.
     
  4. That's just a fuelpump code . Are you running e85? Don't worry about it too much.
     
  5. I just looked up the 2F7E code, The results were DME:Engine switch off-time, plausibility
    There was no fault code description, it is possible that if I had the last 7 of your VIN that it may come up with more information. Generically it comes up with no fault code description.

    It appears it could also be a Superknocking faults as well.
     
  6. Yeah I run 40% e85.
     
  7. Yeah prob just the hpfp/lpfp letting you know it's struggling . Had the same codes, and even with stage 2 lpfp I sometimes get it .
     
  8. Yeah I track the lpfp and it seems like it's holding up pretty well but the hpfp is what I worry about.

    Thanks for your help!
     
  9. Definitely keep an eye on it. but don't worry too much !
     
  10. Maybe this helps a little bit more. If I am not totally wrong, the fault codes should not differ too much between N55/ N54. Feel free to correct me, if I am wrong. Always willing to learn ... Sorry if double post ...

    I got this tonight right after I shut off my car, I have been thinking for a couple day that maybe my battery has been getting weak, I checked it the other day at 11.86v. I'm most likely going to replace it tomorrow, register it, and clear codes.
