I had a DSC light and brake light on the dash. A juddering from the steering wheel and no matter how much I reset the steering wheel angle sensors it would re-appear.
There were various suggestions it could be a faulty ABS unit, Wheel speed sensors, ABS unit, DSC unit. The couple of garages I took it to all said it could be the Yaw sensor and was looking at a lot of money to replace
Over a few months (it doesn't get used much) I found that the N/S caliper was slightly sticking. I loosened this off but it began to stick even more throwing up the DSC light more often. The pad wear was not excessive compared to the O/S hence why I did not think it could be causing the problem. But as the caliper was sticking more I wondered if it could be the issue
I decided to start with the caliper before replacing the more expensive parts and it needed to be done anyway. The caliper was £25 off ebay for a 3.0 Z3 so it was worth the punt no matter what.
With the caliper replaced, full brake fluid change, all corners bled the DSC and other lights have never re-appeared and the car has now completed around 400miles since. The Light was coming on every time the car was taken out.
A lot of people post up the DSC fault so it may be worth checking the calipers as like mine they were original and once out I couldn't even move the piston in a vice and the MPG has increased by around 10mpg and the car actually accelerates now.
