Sad to hear this. I have the same problem. SLIP on loose traction ( looks like car breaks..) after ABS AND TCS lights on. same thing even with TCS off.--after the lights on problem dissapears,yes because ABS and TCS will be turned off by computer
So my question : it is the TCS or the ABS sensor?--I think that it will be the ABS--
No warranty on car,but monday i go to check the car.
Any comment is welcomed,thanks !
