2004 BMW 325 Repair Question
ABS, Brake & DSC Lights On while driving
One of the most accurate and fastest way is to get the trouble codes retrieved and go from there. Too bad generic test equipment are not available for this and you need BMW Diagnosis and Information System (DIS) Tester.
It could be wheel sensors, the control unit or any of the wiring harness. Without retrievng the trouble code, it is like looking for a needle in the haystack and it could end up with more wasted time time and money.
