Hi All,

Car has been fine but now it has developed a very stange fault with the display/stereo.

When driving all the display lights on the instrument cluster would go off including the lights for the Heating and the stereo will turn on and off all this within sort of a second then it will go back to normal and bring up a fault reading of Display faulty please visit workshop and the SRS Faulty message.

Stereo function on the steering wheel is not working now and the stereo is not turning off when the car is turned of & you take the key out, I'm having to turn it off manual by the button every time.

Anyone know what it could be?:crybaby2: :confused:

Sounds like a CAN bus problem. I'd check the wiring behind the radio and instrument cluster. CAN bus connectors are usually brown with a colored tracer. Also, there us a CAN bus connector under the driver's side door sill that can be a culprit - especially if you've had water leaks there.
