I searched and couldn't find the code description so maybe you all can help. I have a Cobb tuned E90 (N54). Went into limp mode today:

Got 3 codes. 2 of them I know what they are, but the last one I can't find anything on:

P29DC Cylinder Injection Shutdown
P29F2 High-Pressure fuel system
P2B2C - ???

Any ideas on what this is? I've gone back to Map 0 in the hopes that I can duplicate the CEL and take it to the dealer, but I'd like to know what I'm dealing with first.

On a side note, would there be any difference for Map 0 v3.0 compared with Map 0 v4.0?

Upgrade to the latest 4.02 maps

Stage 1 doesn't have v4.02, just v4.01 which I'm using.

I think you need to get in touch with Cobb directly. IIRC someone posted those same codes a while back and Cobb asked for that individual to get in contact with them. It has been A LONG time ago so I can't say for sure, though.

Sorry about that, I thought you were using the 3.x maps for some reason.

and don't flash map0, uninstall completely. Just in case they need to do something with the DME

+1 if you are going to the dealer.

I'll keep that in mind, thanks.

I guess the problem with this is that it will reset all the codes once I uninstall right? Unfortunately, the problem seems intermittent and I'll have to drive around uninstalled to see if it happens again. I've gotten CELs before I installed the Cobb, but I had assumed that my gas cap was loose so I would retighten, start the car again, and the problem would go away. I never really checked for error codes until today.

BTW, when I got this most current codes, I was running Stage 1 ST Aggressive with NOS Octane Booster (I'm using ACN 91 fuel).

BUMP

I just popped these yesterday.

P29DC - cylinder injection shut down
P30FF - boost leak
P29F2 - high pressure fuel system

sounds like a bunch of N54 BS to me!

can anyone chime in? I still gotta get home n plug in the BT and see if itll tell me which cylinder is acting whacked out cus the cobb doesnt specify in the read codes... maybe if someone knows the key to the codes thrown such as P29(DC) = cylinder # 5 ?

[zeenon53]

Does DC represent a cylinder code? I threw a p29dc today while doing some logs.

29DC is injector cutoff
