Fault Codes

[sturge]

I have an intermittent warning light on my dash. It is the yellow triangle with the circle/arrow around it. Something to do with the traction control. I assume this because the same light comes on when I get the back end out on the roundabout (thats the cars back end....not mine....too cold).
I have taken the car to my local independent BMW specialist who hooked it up to the diagnostic machine. It is showing 3 fault codes:
C1E24 - Pressure sensor 1/2
C1E21 - Pressure sensor 2
C1DF4 - Battery voltage
Does anyone have any idea what the pressure sensor codes refer to?
I printed off a 33 page list of fault codes from the forum last night and took them to the garage today, unfortunatley non of the 33 pages of codes are the ones I need.

All help very gratefully received

Thanks

that'll be the list i posted then, never thought anyone would actually print them, lol.

If the guy's an Indi, do you know which software he used? It's highly likely it's Autologic, in which case it may have it's own list of fault codes, the ones I used were with my OBD II reader and I've got good results in the past both on the z4m and other cars, but Autologic will be able to read much deeper codes - for example my z4m regularly flags a disconnected bluetooth mic, which I know about, but the ODB II reader wouldn't pick that up.

Annoyingly the only google results for C1E24 are this thread (already) and one in German that doesn't look too helpful anyway.

My guess is that one (or two, C1E21) sensors have failed, as this sounds a similar scenario as when other members' abs sensors have failed (but without knowing the codes).

I'd be surprised if it was an expensive fix, but you might end up needing your dealer, who would be aware of which sensor it was immediately.
