Can anyone please suggest a solution to my problem. - I have an intermittent issue with my Left dipped headlight. There are times when them the lamp does not illuminate when switched on, and I also get a fault message on the multi function display. In the past this has eventually rectified itself without any intervention whatsoever. My problem is that the car is booked in for MOT on Thursday 24th May, so I need to make sure that the lamp works. The car has bi-xenons (option 618).
