burago_2003 0 Report post Posted July 12, 2012 Any idea why ASC light would come on suddenly? It was working fine, took it to BMW to get some work done and when i got it back, switched on the car, next thing i know the light came on..Now apparently they did some grooming on the car and the mags are shiny as, so have a slight suspicion however they've been cleaning it could be a bit of water that got into the breaks and kicked the sensor off?? Any help would be much appreciated! p.s: apologies if this has been posted before, i tried trawlling the forum for previous posts but couldn't find anything Quote Share this post Link to post Share on other sites
liyi_92 37 Report post Posted July 12, 2012 Sorry for a stupid reply but, Did you press the ASC button to see if you can turn it off? Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted July 12, 2012 As above. If so & still on - why not take it back to them & get them to check? - since you picked up the car with the light on:- Haven't got the ABS light on too have you? Quote Share this post Link to post Share on other sites
burago_2003 0 Report post Posted July 12, 2012 Yep tried to switch it off using the button and wouldnt switch off and no there's no other lights on... TBH don't want to go back coz i know they'll just charge me more money for a flippin reading then come up with "something that needs fixing" ...

liyi_92 37 Report post Posted July 12, 2012 Once that happened to me and it was because the brake sensor dropped out. But if that happened your car should not be moving past 2nd gear. Try d/c the battery for 2 minutes and reconnect. Turn engine on (if light still on take it for a wee drive) Turn off engine, leave it overnight. As above it worked after I had replaced the brake sensors and ASC light was still on. Next morning I switched it on the engine. Light disappeared. Funny that.

A scan showed an ASC fault which turned out to be a broken secondary throttle cable - cost about $25 for a replacement cable and voila... No light! Worth checking to see if it is slack or frayed.

If it is like you are telling - the problem arose as you drove off from there. If this is the case - tell them this. If it turns out to be something they created - they will have to fix. If it is coincidental & is another problem - it still needs to be confirmed & repaired. Quote Share this post Link to post Share on other sites
