DTC light on 1997 328i sedan -- need advice
The dash light stays on constantly. It shows a triangle with an "!" inside it and an open circle with an arrow outside the triangle. I cleaned all wheel sensors and filled the master brake cylinder. Do I need to reset the light or is there another problem? Do I need to drive it to reset it? Do I need a scanner to reset it? What is the "ASC" button in front of the gear selector? Is it related to this? Appreicate all the help I get.
