I have just purchased a 1.4 Tdi SE and the main lights and reversing lights have all of a sudden stopped working. I have checked the bulbs and the fuses and all are ok.
Are you *sure* the fuses are good? have you actually replaced them, measured them or just visually checked?
the switch can die.. but what do you mean by the "main lights"?
I am referring to dipped beam. We have made a visual inspection and also replaced with one we know is working and that too doesn’t help. Fuses and bulbs are all fine. Side lights are working as is main beam.
interestingly the lights on buzzer has also stopped working.
Then I think two different issues. One is possibly the light switch. For the reverse lights, I would double check the bulbs but it could be the switch, too.
