Today I have noticed two more problems with my car.

The first is the dial sweep fault which seems quite common where when the ignition is turned off the temp and fuel gauge go to the left then go straight back to the middle indication.

The second fault I've been having for the last few days is when I go to turn my car on sometimes it doesn't turn over. It doesn't seem to attempt to do anything. If I hold the key for about 5 seconds or so the engine then starts to turn over. This is intermittent though as sometimes the car starts first time. Could this be a dodgy relay? It happens both when the car is cold and even if it is still warm.

Could these faults be an indication as to why my MPG has dropped?

Thanks,

James
