Normal Codes On a Tuned N55 - BMW 3-Series (E90 E92) Forum

fasteddie222 · 01-10-2013, 01:18 PM

I want to make this thread so we can all post up codes that are normal because a lot of people post up threads asking about codes. Here are a few normal ones that come up if your tuned.

3106: Catalytic converter: Efficiency below limit (Catless code)
2C90: Blow-off valve, mechanics: Jammed closed
2774: Mass air flow sensor, plausibility: Air mass compared with model too high
28A0: Throttle-valve angle - intake-manifold pressure, correlation: Limit value exceeded
2e4c
2775
2bc0

Good thread idea. Should be expanded and stickied.

This is nice fasteddie... since I went ISO I get this code 387F (Power management, closed-circuit current violation). I don't know if this is an ISO tuner code. I e-mail terry but I just sent him a bunch of code along with this one so he really didn't tell me anything about it. Maybe if I e-mail him this single code. Car runs great anyways. I think it might be an ISO tuner code because he mention that the board will run hotter with the diode cut, just my guess.

I thought it was a good idea because people get codes and freak out thinking there is something wrong with their cars. With this thread they can actually look at what codes come on regularly and shouldn't be worried about. Btw I have no idea what that code means but if terry says is normal post it back up here

This is a great thread. Good thing you posted this. I just got 28A0 today. I took off my downpipe and everything. Do you know what causes this code? Is it just over pressure since jb4 tunes it past stock psi?

I have no idea what causes the code but you don't need to worry about it. My buddy is a BMW tech and he told me not to worry about it so I trust him. If you want email mike@n54tuning.com and he can explain to you why you get that code. Goodluck

New Codes
2e4c
2775
2bc0

bdoooh · 04-15-2013, 07:35 AM

I got 3 codes this morning..

387F
28A0
2C90

I'm assuming they're tuner codes & I shouldn't worry about 'em.

P2C57 I've been told is a boost leak .....
P2D43 ... Not sure about this code.
Got the two codes on the track at 120mph on the straight

I always get that code but have no idea what it is

Finally! This thread is long overdue and needs to be stickied!

Ranoz · 04-29-2013, 03:18 AM

New code
Engine fault, reduced power
P2BDA not sure what this is, but i can tell that the power is actually reduced when I push hard

emackin · 04-29-2013, 06:43 AM

i believe 387f is the battery cable recall code, i just recieved letter in the mail about the recall.

you might want to check "the other site" which has the official codes list from BMW with descriptions and troubleshooting information.
