BMW 335d
just in case any of you ever have this problem...come out of pub after a quick pint after work about half 5 last night and my headlights came on (autoomatic ones) but it didnt look like the and of the dash had lit up but waited till it was really dark so i could tell properly. Sure enough, the lot was out, even the lights behind the window switches werent working and i couldnt see how fast I was going. All the fuses were fine so I got my mate to have a look (hes an audi technician) eventually he found the fault, the relay packs under the dashboard on the passenger side had fallen out. He pushe them back on and on came all the lights. Dont know why they fell out. Typical Renault build quality maybe?
