1998 528i E39150,00 miles ABS, ASC light shift issues
My ABS and ASC light both came on at the same time after driving 11 miles.. The asc light would not turn off when depressed. Car operated fine the remaining 6 miles to work. When I started home the lights were not on at first. Before leaving the parking lot both lights came on again. This time when I started to leave the transmission would not shift from first gear. I came to a full stop and tried again, same results. I then shifted in 1 and accelerated slowly then shifted to 2, transmission shifted fine, then shifted to 3 and shift was good. I had to do this each time from a full stop. After I reach some speed placed in D and transmission shifted into the overdrive.I can start the car sitting in garage and no abs and asc light. After running for a few minutes both will came on. This is without the car moving. Also speedometer and tach work fine and no transmission limp indicator illuminated. Sorry for the lengthy description.

i will start with scanning to make sure but the problem you have is one of the 4 or more than one of the abs sensor are bad this is the front side(2) number 7 on the picture this is the rear side(2) number 24 on the picture

I had a similar issue a year ago, it was my front right wheel speed sensor. Don't cheap out on sensors either, cheap Chinese ones will not be built to the proper tolerances.

Thanks to all. Here is a new one. I crawled under vehicle to look at the location of the sensor. Mud was caked up on the passenger side front. I took a hose and washed off the best that I could. Drove to car to work today no lights or shift issues. She will get a wheels off cleaning a.d inspection this weekend.
Again thank to all.

The insulation on your sensor is probably frayed and the wiring is shorting out if it gets wet. If it rains before you get a chance to clean and inspect the assembly take your car for a drive and see what happens.

Hey wildbill528i but what L0F told you about "Don't cheap out on sensors either" he is right find the good ones because you will waste your time
