I have narrowed down my cruise control fault to the braking system , but need someone who know s more than me to shed some light on the problem .
I am getting the engine light on, VDC ASR and Hillholder , no cruise control , Unavailable and the fuel gauge dropping to zero when the fault occurs.
its showing a P0564 (multi function input circuit 'A')
i have changed the brake and clutch switch and they are working fine .
the fault occurs when you press the brake pedal and hold it about half way for more than 3 or 4 seconds. all the warings come up and the fuel gauge drops to zero.
the fault clears if you apply more OR less pressure to the brake pedal.
i have even disconnected the brake pedal wiring so as to rule the pedal switch out and the fault still triggers.!!!
this must mean that it to do with the braking or abs system its self .
does anyone know what it could possibly be ?
help urgently required please
or can someone recommend any one who would be able to get to the bottom of this issue. its already been to the main dealer and they are useless, and an auto electrician and my local specialist . Wopuld it be worth a trip to AutoLusso ? are they any good?
im in southampton by the way
