One for all you helpful lot.....
Popped out at lunchtime and the bulb warning light illuminated, soon after the MFD started telling me to check all sorts of lights, fog lights, number plate etc etc, it just seemed to go through the whole list. The indicators were flashing double speed, suggesting it was one of them that had gone. When I stopped I put the hazards on to check and the rear ones illuminated solid (not flashing) whilst the front were fine, by the time I got back to the rear they were flashing normally. Didn't have time to investigate further and by the time I left work the warning light was off and all seemed fine - surprise surprise!
A mere glitch or an early indication that something is about to blow!?
