i like it ... wana start with one of mine ? haha

2F7E - UNKNOWN DESCRIPTION via jb4 and mhd shows NO CODES!
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.

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.

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.
