Hello hope someone out there can help. On my wife's 03 C3 1.4 diesel. She encounted a problem. Sometimes when the car is switched on & runnning we get a total failure of speedo, rev counter, fuel, temp and all other displays with that cluster. Also when you switch on the radio it beeps very 10 secs or so. Then when you switch the engine off the fault disappears. This can also occure when you travelling down the road which is not good at speed. This can happen at anytime. Can anyone suggest a suitable fix :rolleyes: ? please
