Brake Error Light, Reduced Power - Anyone??
So, I was autoxing recently and during my first run my car all of sudden shows a brake symbol with an exclamation point error light on the dash. The power is reduced and the revs jump from 1.5-2 up and down. I shut the car off, turn it back on and it's fine. Out of 16 runs it happened 8 times.
Also, I always turn both DSC/DTC off. I've been Autocrossing the car for 3 years, and have not had issues before. Later in a run where I didn't get the error message, my brakes locked up - no ABS. Took it to the dealer and they checked for faults. - Engine Power reduced due to brake overheating (however, it was my first run and I doubt the brakes were hot, and it didn't happen in some of the later runs). - There was also a wheel speed sensor fault. They have no idea. Does anyone have any suggestions?? Thanks.

Thanks for the suggestion, but I have the ATE race fluid in there. Also, it happened when the car had been sitting for 2 hours.

Wheel speed sensors, length of brake usage, pressure of brake usage, and ambient temperature. Hopefully cleaning the wheels speed sensors will change things. If not, I can replace the ones that are registering the fault.
