    Limp mode - Help with code

    Experienced limp mode earlier today while driving normally. Checked codes with cobb and came up with the following:

    P2F15
    P3100
    H2AAf

    Anyone have an idea what P2F15 stands for? Did a search and came up with nothing.

    Try Google searching the codes, they'll probably come up. At least if you post the codes w/ the code description, people might be able to help diagnose

    I spent a few minutes searching but couldn't find anything. Email cobb technical support, they were able to provide definitions for some undefined codes i had pop up while beta testing some maps back in the day.

    Cobb had no clue either. They told me every other codes in the vicinity was AC related. I've since cleared it and hasn't popped up. Next time I may get someone at the dealer to read it just so I'll know what it is.

    If it comes back, try to find someone with INPA or an independent shop to scan it.

    I searched every piece of data I have here and couldn't find any reference to this code... Click here to enlarge

    As tech support said, I could find codes very close to this one (2F12 A/C Clutch relay control circuit high) but no reference to 2F15. Click here to enlarge

    Sorry we couldn't be of more assistance, you've got an odd one. Click here to enlarge

    Bumping old thread, just popped 2F15 & 3100 together, CEL/half bounced to 0% WGDC limp. Like you I couldn't find anything on 2F15 (except this thread). Just posting to throw it out there for the sake of data. I'm on a mildly tweaked OTS race E30 map.

    3100 is boost pressure control, probably solenoid related at a guess.

    I'm reading that 3100 just signifies a limp event took place. It always accompanies another code. The undefined 2F15 is curious, was just cruising at 2krpm, hvac off.

    3100 is just to tell you a limp event was triggered but it's not an underboost code so nothing with boost control is involved.

    limp was probably due to the 2F15 which no one knows what it is :s

    Sorry to revive the zombie post but I just had two codes pop up today while driving home. 2F15 and 3100. They came up while driving home normally, windows down, cool night (~75*F), D mode (auto trans), car warmed up to 190*F. Cleared the codes but 3100 remains. My search on these codes lead me nowhere but to a few threads where no one knew what the 2F15 code means. Figured I'd revive the thread in case anyone had any new info.

    Same thing just happened to me. P2f15 and p3100. Didn't clean codes just turned off and restarted and it seems to be running fine. Any new thoughts on this?
