I have a 2005 Mk 2 Focus, it's a 1.6 TDCI LX. Recently while driving home the engine fault light came on. I decided to pull over and check the engine. Nothing seemed out of place on it. So I set off again. When I started the car again the light went off. The same happened again this morning.
I get the car serviced every six thousand miles. This includes changing air, oil and fuel filter. The car has just done over 104k miles and is due to have the timing belt changed at around 125k miles.
Is this serious or can I let it slide to the end of the month?
Thanks in advance!
