Hi: Both my ABS and ASC lights have been on for the past week. I hooked up my Schwaben scanner to the in-car OBD-II connector and pulled code P0500 - Vehicle Speed Sensor - 'A'. Not sure if they are referring to 1 of the 4 wheel sensors. Last year I had replaced the driver's side rear sensor with a genuine BMW replacement part when the lights were coming on intermittently and the speedo stopped working for a short period of time. That seemed to have fixed it up until about last week or so.


We've have a bunch of cold weather here in the past month with sleet and snow, so not sure if that sensor may have gotten boogered up, or if that code is referring to some completely different sensor. I can erase the code with the scanner, but the ABS and ASC lights do not go out, and the Check Engine Light comes back on after about 25 miles or so. Any help and guidance is appreciated.


Regards, Chris.
