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?
Codes... And Solutions
- Thread starter Cheezy

That's just a fuelpump code . Are you running e85? Don't worry about it too much.
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.
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 .
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!
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.
I have the shadow code
2FDB
Currently just a custom MHD tune and Bmw P muffler.
HPFP replaced May 2017
Should I worry?
I do have a fuel it stage 2 LPFP in the living room.
Thanks for the help

Weird my post vanished.
I have that shadow code 2FDB
I’m only stage 1 custom tune with Bmw p exhaust should I worry?
I’m going FBO next week so I don’t want any underlying issues!
Thanks guys

Youre post is still there. Ive heard 2fdb is related to the hpfp software, but not a sign of failing hpfp. You will get a shadow code for your new stg2 lpfp tho, just basically saying it draws more current than intended. No big deal. If youre concerned with 2fdb maybe take it to a dealership and ask them to update the software if its not current.
Only just seen post buddy!
Thanks for the reassurance. Pick up car today full bolt on haven’t put the stage 2 LPFP yet!!
Thanks again bro
