I picked up a 2000 X200 3.0 V6 SE auto in September. It had an issue with the traction light constantly flashing. I took it to a grage and they diagnosed a front wheel sensor, which they replaced and it went away. A short time after I had the front discs and pads replaced, and the fault came back, but this time I had the flashing traction light sometimes and a constant traction light at others. It seemed to flick between them with each successive engine start. I took it another garage, and they did a calibration on a steering wheel sensor, and the car was fine for a week or so. Then one day I was driving along and I got "DSC SYSTEM OFF" followed a few second later by "DSC SYSTEM FAULT". I took it back to the second garage and they cleared some codes and it was again ok for a while, but then the "DSC SYSTEM OFF">"DSC SYSTEM FAULT" happened a few times so I took it back. They said that it looked like the ABS unit could have a fault, and that the best thing to do would be to send it away to a specialist for a repair. I decided not to proceed at that time as there were a bunch of other things the car needed, and I had a really good run from that point where I didn't get any fault lights for a few hundred miles. Then last week the "DSC SYSTEM OFF">"DSC SYSTEM FAULT" happened while I was driving, and it's been showing "DSC SYSTEM FAULT" ever since.
