My Abs Light Came On!? Help!

[Delmarco]

So last year July 2004 my check brake light (rotors) came on. BMW of Manhattan told me the problem. And I got new rotors and (i think) pads at their BMW dealership and since then over the year I've put 17,000 miles on my car.

This morning my ABS check light came on....but of course my brakes are working fine. I'm not sure what should I be looking for. Does this mean I need new pads, rotors, sensors, what?

Thanks.


I know if I go to the dealership its about $500 alone to look at it.

probably one of the speed sensors are gone, the part is moderately expensive and the labor can be a pain just because sometimes they charge for more than it takes (they do this because sometimes it takes that long)

It could be as simple as the plug under the dash coming out. check that first, and also check the fuses, too.

An ABS check light is most often caused by the failure of a wheel speed sensors, but it can also be caused by the failure of the ABS module or wiring faults. It has nothing to do with the brakes or rotors, per se.

It could be your ABS sensors or your ABS pump. If it's just a sensor, you're in luck. If it'd the pump, then try to find someone who is willing to sell you one off a parts car that was known to be working. They are expensive new.

Clean your ABS sensors first. And go ahead and replace the relays. Both are cheap and easy to do. If not the pump sometimes fails.. But you want to make sure of that first. You could always test to see if your ABS works by finding something slick to brake on.. Low speeds and with no traffic would be good..


Thanks Furious,
above is a summary of what I heard so far from various tech sources.


But where can I find those sensors/speed sensors...etc?

Call bavauto. They can get anything for your car. They just don't stock everything. I would just call to get the price. I would also call the dealership.

Good luck. I hope the problem is nothing serious. Bad brakes ca be very, very dangerous.
