<newbie>: Check Brake lights

Hi

Only picked up my used X5 on Friday 25th March 2005. Love the car - best I've ever bought so far.

Unfortunately got the "Check Brake lights/Check Tail lights" message on the dashboard on Sunday.

I've bought replacement bulbs and have unscrewed the bulb holders from the taillight fitting - but all the filaments look OK. I have changed the bulbs but no difference.

Maybe its a fuse problem ??

I've found one fuse box located close to the right taillight fitting - but none of the fusebox places are defined as being allocated to the taillights?

Is there another fusebox I should be looking for?

Or am I on the wrong track - could it be some other problem?


Any help much appreciated

Thanks
Paul
