The f literally lit up the second the car cut out, that's why I guessing it's connected. No other light are on and nothing is flashing.F relates to the outside temperature sensor. It's telling you it has a fault. The sensor has gone **** up and is either disconnected or U/S. A new one is only around a tenner from the dealer, or slightly cheaper on ebay.
No connection with your car not starting. Any other warning lights lit up? Car/spanner light flashing on and off for example - which is indicating an immobiliser problem.
Yeah I see what you mean about the f but it's on the botttom line of the display not the top line, Ile have a go at the pedal test and see if I can get some codes.With car off put foot flat down on brake and accelerator simulationously, turn key so dash lights up but noy starting car, codes should begin to flash up on the mileage display, may take a couple of attenpts to get it working. Post the numbers here and may help diagnose the problem. As dave says f usually is the outside temp sensor but it can show for easytronic problems I think and possibly cim faults but I'm not 100% sure! Best just to get some codes to work with first and go from there.
