I had big question with my 2001 BMW X5 3.0. Recently, the ABS, brake and DSC light on. Have you ever met such awkward situation? Here I will try my best to explain the problem and solution.

Once when I ready to pull my vehicle, I found the ABS light and DSC light came on. Then the engine went to failsafe mode and accelerated at a low speed. Brakes failed to work properly by showing yellow light. Besides, the lights went by themselves after warm place for three minutes. I have to turn the DSC by myself, but unfortunately these lights on few minutes later.

I realized that it was the time to diagnose my vehicle with a quality BMW scanner. Then I hooked up my BMW scanner V2.20 K+DCAN to pull dup form ABS module, then it displayed 118 and 908 error code. Then I googled what do they refer to. 118 stands for DME status problem and 908 meant intermittent system was down.

Then I pulled my vehicle to the mechanic. He first inspected the battery to check when I replace it. A weak battery may lead to such problems. After confirming that my battery is original and had no problem. The mechanic suggested to get my EML (Drive-by-wire system) replaced. He explained to me that if there are any faults in the EML system, it will immediately shut down the entire DSC system and go into failsafe mode to prevent any unplanned movements of the car. It could be as simple as a bad accelerator pedal, or a bad electronic throttle body, or even a wiring problem between any of the control units.

Well, finally the problem was settled but I lost big money.
