When the car is running the orange key symbol flashes.
It is flagging error code b2799 which is related to the key ecu and engine ecu not communicating. I have used tech stream and the car will do a "handshake" with the key using the start but and recognises it but will not pick the key up any other way. I have tried this procedure with another ecu that the car would notrun with and now ot will run but it still requires the emergency start procedure.
Does anybody have any ideas or should i have started a new thread.
Thanks Chris  |
Replace the battery in key fob will sort it
If you have a read of owners manual it explains the key symbols and beeps
