HI
I have just had a full set of pads and new exhaust fitted and now I get a warning come up ESP not functioning. On my Citroën C5 2004 Estate 2ltr
I have taken it back to the mechanic and he cannot find the fault. He said he had it put on a diagnostics machine the machine said steering angle sensor problem. He says he doesn't know where the sensor is or how to cure the fault.
Can anyone suggest what the problem could be and how to correct it.
Thank You
