Answer
You need to access the vehicles computer system via the climate control panel and see what fault CODES you get on the fuel data display.

1. Turn ignition key ON. Do NOT start engine.

2. On the climate control panel push and hold the OFF and WARMER (^) buttons for 3 seconds and release them.

3. Look on the fuel data display and you will see LETTERS & NUMBERS appearing and it will stop.

4. Tell me EXACTLY as if you were video taping the display what appears on the screen.

5. Turn ignition OFF.
