(98-05)318i 2.0 Auto ASC Unit continuously running - laser
The ABS/ASC Warning lights appeared on the dash and when I pulled over and stopped, the ASC unit was running all the time even with the keys removed from the ignition. The only way to stop the unit running was to unplug it, removing fuses did not work. I wonder if anyone else has had similar problems or some idea of what may cause this ?


Please read the small print, nice to have year and engine in subject line and NO NEED TO SHOUT........PU!
