Just ran a diagnosis with BMWhat and a bluetooth ODB adapter, and it came back with a number of codes. It doesn't seem to show any dates as to when these codes were raised, nor does it mean too much to me, even after some serious Googl'ing.

Anyone able to shed some light on the below? Nothing is reported whatsoever in Check Control.

Code: 2B05
Code: A559
Code: A8C3
Code: 9CBA
Code: 9CC3
Code: 9CC4

Thanks,
Chris.

Code: 2B05 Performance related / linked to DSC. Not sure what it is.
Code: A559 Related to speedometer, would not worry. Low battery related
Code: A8C3 ?
Code: 9CBA ?
Code: 9CC3 Related to side mirror heating
Code: 9CC4 Related to side mirror heating

Thanks,
Chris.

I will double check the side mirrors heating.
And look at performance issues (if you have any).

Thanks for the reply Makkan, appreciate it.

2B05 - DSC as in the stability control? There are no performance issues whatsoever, car runs absolutely fine.
9CC3/4 - hmmm haven't noticed any issues with the wing mirrors. They seem to clear pretty quickly. Will have a look.

Is it best to clear these codes via BMWhat (if that's even possible?) And see if they reoccur?

[ChrisN53]

So I cleared all the codes via BMWhat, and used the car as per normal. Did a diagnostic just now, and only one code reoccurred. Details taken from the BMWhat log are:

Motor Control:
Engine / Motor

Fehler: :Pedal value sensor 1 / Throttle potentiometer 2 / throttle 2 / Air mass meter, signal correction / Accelerator pedal module , pedal sensor 1

Code: 2B05

Any ideas??

Sorry had a busy day so could not reply to your question.
When you go on your local meet, ask somebody to diagnose it with bmw equipment.

Cheers for looking at this Makkan. Is there a preferred diagnostic tool/software you'd recommend?

[grimwood1992]

I have a similar code p0122 throttle position sensors low circuit :/ still baffled as car runs fine

I'm sure Makkan would recommend BMW OE tools.

INPA
DIS
or most recently ISTA D (Rheingold)

All work with K+DCAN cables and are freely available on the Internet to download.

Just bumping this thread. I thought I'd run a diagnostic with the upgraded BMWhat app, and I have done about 4 now, and the same code keeps appearing. I clear it, run the diag again, and it re-occurs!

The car drives absolutely fine, but I really want to know what the fault code relates to! Googling is bringing up very little. Just wondered if anyone else here had encountered it. Thanks.

Motor Control: Engine / Motor

Fault: :Pedal value sensor 1 / Throttle potentiometer 2 / throttle 2 / Air mass meter, signal correction / Accelerator pedal module , pedal sensor 1

Code: 2B05

This might be a long shot, but have you definitely selected the right engine on the app? I once accidentally selected the wrong engine and ran a diag, and got super worried by the list of codes it brought up. I eventually realised I was on the wrong engine, changed it to the right one and re ran the diag, and no more codes! It's just a thought....

[ChrisN53]

The correct vehicle (2007 325i N53B30A) is selected. So unfortunately, I don't think that is it. The internet is showing that the 2b05 code could be to do with the NOX sensor as well...nothing definitive unfortunately
