Brake,ABS, DSC lights on - Page 5

Bigtom,

I've been having that issue for a while now. I was told that it is the DSC/Antilock brake module, the part is $1200-$1500 (depending on where you go) but I was told that Modulemaster.com will rebuild it for $300 and guarantees their work. I plan to send mine to them but I havent found anyone that can remove the part for me. It is driveable even after the part is removed. Let me know what the "stealer" tells you.

The car is back from the dealer now and I am happy to report that it seems to have been cured. No warning lights and all functioning ok. Even after a long and fast drive on rough and rugged polar winter roads yesterday, still no warning lights

At the dealer they checked the log without being able to draw any conclusions, luckily they didn't do any blind attempts on changing any sensors. They cleaned some main connectors, and they suspected that one close to the gearbox could be the reason for my trouble because it was a bit greasy. Finally they reset the computer and, voilá. So far.....

Told me they had used five hours, but would charge me only for three

If I'm really lucky BMW Norway will refund me as a part of my guarantee.

Its the steering angle sensor. The part costs about £70 and its located somewhere near the steering rack. I had it a few times, normally comes on after driving for a bit, goes off when you turn car off (re sets its self) and comes back on after a while

Ended up being a bad ABS Sensor Right Rear. I had to drill it out with a 1/2 titanium drill bit. Tried to wiggle it out. The darn thing was solid. I ended up breaking off the top. Only option was to drill it out. Works great now, no lights, after replacing it.

Damned, - I have all the warnings and the transmission failsafe program back.

a wild guess here, but it could be the battery this time??

This is easy...start your X, center the wheels, turn full right, and then turn full left and then straighten the wheels back out....the system will reset and the lights will go out. It happened to me in Dec08 and last weekend as I changed my battery...ALL GOOD.

The best bet for everyone here is to go to the dealer, or better, a local shop that has the European scan tool.

It turns out that all this fuss on my car was caused by the $110 left rear wheel sensor. That's it. I thought it was the ABS module, wasn't. I thought it might be the harness. It wasn't. Thinking got me nowhere, just bring it to someone with the European/BMW scan tool and be done with it.

Don't oversimplify the system... it could be anything from sensor calibrations, faulty pressure sensors, faulty wheel speed sensors, faults instrument cluster, faulty DSC module, etc. It will be different on a case by case basis which means you really need to have the faults read and analyzed, but by someone who knows how to diagnose the system. I've seen right rear wheel speed sensor faults caused by a bad DSC unit, left rear wheel speed sensor faults caused by a faulty instrument cluster, etc. Proper diagnosis is unavoidable in some cases.
