Five yellow lights Help

**JezP** · 18-09-2010, 06:22 PM

Hi all

Got a problem today with the motor only a brief drive to pick something up locally. DSC-handbrake-ABS-Runflat-Gearbox light's all came on suddenly but what was more of a concern was when i pulled up the throttle revved to the full on it's own the car was stable and my foot was no where near the acc pedal. Car is safely back tho so it's a trip to the techie's ASAP had a search about this but could'nt find much info but just wondering if anyone has had something similar to this or read anything somewhere else and might know roughtly what the damage is

Jez

Took a pic btw..

Normally when you get a failure across all those systems it's down to a failure of a common sensor such as a wheel speed sensor. Those systems all take a feed from the WSS. From memory I think the steering angle sensor can have the same result too (not 100% on that). Only strange bit is the revving engine! Plug it in and the answer should be in the error log

Wheel speed sensor? No idea about the revving on it's own though.

Mine was a wheel speed sensor[ABS] same lights on dash as yours,all done under warranty,but i think the part was about £80.As Elliot says,same lights for steering angle sensor.Revs are a bit strange though,after hanging around m3 forums for a few years ive never come across that before.Hope this helps anyway.

Loose battery terminal ..go check

Cheers lads

Not too bad then although the engine build up rev going christine on me was a concern it was as if the motor wanted to launch it's self very odd.. has been mapped?

D... ive checked under the hood for things like that lights are still there.

As has been said, most likely is wheel speed sensor but revving suggests a throttle position sensor instead.

I was interested to see your posts and the answers and wondered what it turned out to be?
I had something very similar on my old E30 Sport Evo. Virtually every warning light came on constantly or flashed intermittently, as well as the rev counter going berserk (no actual revving of the motor itself though). It turned out to be a failing alternator. Curiously, the only light that didn't come on during all of this was the red 'charge light'! Before someone suggests a duff bulb, it was good.

Hi mate

Good knowledge here as it was the wheel speed sensor.. as for the rev nothing was found to be wrong i cant rememember what george at techsport said about what the problem could had been wasnt concentrating to busy sizing up the bill as other things needed done

Hope its not the alternator on its way out tho thats the last thing i need with silverston next week.
