ABS/DSC Light Issue
Recently bought an 2002 E39 M5 with 90K miles. Drove around 200kms in December, then stored it, until last week.
During storage, I made some basic maintenance on it. Flushed the brake fluid with the motive brake pressure bleeder. Previous owners seem to never had done maintenance on this because there was some gooey stuff that came out from the calipers.
So last week, after driving less than 5 miles, the ABS/DSC lights came on. It will go off after turning the car off, but randomly comes back usually after driving only a few miles. I will also light up when the car is stationary.
INPA gave me the following codes:
- Brake switch 105
- pressure sensor 114
- steering angle sensor 103
Cleared them and drove some more, lights came back, and now getting only the 114 code.
When lights are off, ABS and DSC works fine. Activating valves and pumps with INPA makes noise so I guess it' all working fine. Brake pads are good too.
What should I look for to pinpoint the problem? Could it be that some of the old fluid interferes with the system? Did I get air in the system? (pedal is firm though)
Also I've installed the shark injector that came with the car, could it be the issue?
