I've had the engine management light come on TWICE in the three years i've owned my 2003 / 2.3 ltr Gal Zetec...each time it's been down to the failure of the front side light. Replacing these bulbs is a bug**r as you have to access through the small wheel-arch sliding flap...then locate, twist and pull out holder (eventually)...i still have the wrist bruises from replacing the second one as recently as last week! So, YES, it can be down to a simple bulb! :blink: (p.s. i then had to hold the wee black 'milegae zeroing' dashboard switch in as i turned on the engine after bulb replacement (i believe this resets the dashboard light after the fault, bulb, has been rectified)
