ABS, BRAKE & DSC LIGHTS ON WHILE DRIVING

2004 BMW 325 • 6 cylinder 2WD Manual • 179,000 miles

I own a 2004 BMW 325ci and recently I had the car detailed and the engine compartment was cleaned with some kind of cleaning solvent. Since then my ABS, brake light and the DSC light is on. What sensors you think was damaged? How do I fix the problem?

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.

The DSC module is at fault, let me know what you want to do
