E39 540iA FAILURE: ABS and ASC lights

This happened yesterday night. I was braking to stop at a sign on some snow, as every body does normally. As soon as I released the brake pedal and hit the accelerator normally, i notice that the ASC and ABS light lit on in the dash. Since that time, no more ABS or traction control.

Anyone know what's happening with the car. Car is a 1997 Canadian E39 540ia with 150 000Km.

Thanks

ABS and ACS off?? FUN TIME!

Actually...i'm a believer in ABS...so...blah, anyways, FUN TIME!

I remember the BMW driver training course, all the student cars were fitted with a fun switch where it kills the ACS and ABS.

have the the ABS scanned.. your abs and asc are connected as one since the car needs to apply the brakes when the asc lights up..

more times than not its a wss... see how that goes
