Just bought a 2 litre petrol 03 mondeo ghia x estate and the display on the rev counter is showing outside temp all the time. Pressing the info button gives a 'beep' but nothing changes, the reset button changes the C to F but prolonged pressing does nothing. The car has recently had a new battery if that helps. Has anyone any ideas? Other similar topics on here are not for the exact same fault as although my info button does not work, it does beep.
