DSC off permantly

**Fasteddie** · 09-06-2010, 01:02 AM

Hi a techy question for all you electronic control geeks

I love you every last one!
I had this at the ring and Mat CSL Nuttbox cleared the codes ( I love you Mat very much but not in a

way

), I have listed them below. I have been happily motoring without a problem but it has come back and the two lights have come back on (DSC OFF light) is now on, along with the brake light (the one that is red when the hand brake is on but normally goes off when released - mine however goes orange. The only problem with this is the DSC is actually off and it's not just the light on on the dash. Fortunatly, when i was in the car, the weather was good - however it has been lashing down in between times. now I guess this is some kind of ABS switch problem so does anybody know what the codes refer to?

CODES
Pressure sensor 1
Pressure Sensor 2
Can Instrument

Stop it U tart

you're making me blush

Sounds to me like U have at least two ABS sensors down. When they fail the DSC is automatically disabled as it relays on the said sensors to relay info. I think it's time to pop down to BMW main steelers (if you have BMW warranty) or BMW Indy if you don't, to determine via their diagnostics exactly which two ABS sensors are inoperative and get them changed

The car instrument fault code could be a faulty/dirty hand brake contact sensor or something in the display cluster but it's probably linked to the ABS sensors. Does anything change when U release/engage the handbrake ?

I had this come up last week when 1st turning ignition after changing Rear Pads. Turned ignition off, Waited.... then turned on. Cleared!

i had a similar problem - it's a sensor on the steering wheel column that will have come loose - mine actually stopped showing after i went over a pothole - large thump sorted it out...

The brake light is red with hand brake on then orange when released. The DSC is OFF all the time and S6 is showing

Mine is doing the same.

I have replaced the ABS pump with a second hand one from craig (long storey but a good one) just in time to go to the Ring.

However lights staid on (brake light and traction light) but figured it would be ok to drive to Germany.

So I went to several garages in Germany, but it had to be a main dealer who could sink up the different pump. Lights out, test drive sorted.
10 miles down the road lights back on again!!

This has happened several times since, even at Spa, hence my reluctance to drive at any speed in the wet.

Since retunring to the UK the fault code still says ABS pressure sensor!!??

My question is, several mechanics looked at it in Germany before the main dealer and they all pointed toawrds a steering angle sensor!!

This feels like ground hog day, only a bit more costly.

Any advise/experience of similar probelms would be very helpfull.
