ESP and ABS lights on

[jonninorcliffe]

Hi, iv had an ongoing problem for a few weeks now. First of all i went for a quick drive dropping a family member off, as i dropped them off my ABS and ESP lights came on and my speedo stopped working. i have replaced the ABS module and recoded to the car and my speedo is working again, also replaced front left wheel speed sensor and driveshaft complete, but ESP and ABS remain on. i have checked all fuses relays etc, tried tracing wiring but not fully. something has gone somewhere and im struggling now. Does anyone have any ideas to try? Next step is auto electrician but if i can sort it myself first it would be a bonus. im good with spanners and ok with electrics, im just fed up of head scratching now. Lights are HARD and will NOT clear.

check the wiring on the abs sensor you fitted it could have a break in it also for the esp light do a steering angle calibration using vcds

Steering Angle Sensor (G85) CalibrationBefore starting the procedure turn the steering wheel at least 30 ° left and back straight ahead.

I had this, it is a fault with the brake switch that the pedal pushes against.

[Pezperry12]

Did you ever fix this problem mate

[MarkJL]

Yes, new brake switch sorted it out.

[A4B6Cab]

Yes, new brake switch sorted it out.


Mark JL, did you need to erase/clear the fault code after you replaced the switch? I've replaced the brake pedal switch but light is still on?
