Hi guys. Weird one- I've changed interior bulbs to LED earlier today, (much better I must say) went out in the car this afternoon and when I lock or unlock the car now the exterior lights don't come on. I've checked the settings in the car and they should be on. Anyone have any suggestions as to what the problem is. Surely cant be anything to do with swapping the interior bulbs, can it? Also which lamps should light up as DRL cos I'm not sure they're working either, but when I switch the lights on manually ALL lamps are working. PS I am new to A5 ownership so please be gentle with your replies ?
