I have an early 2002 E46 330D Touring.
It has brilliant headlights and the self leveling seems to work just fine when ever starting the car and light is dim enough (it has auto lights).
I believe that for the xenon lights to have been fitted from new that the lights should have washers or wipers, mine however does not, but i would think the lights are still fitted from new as the original owner bought every conceivable extra option apart from the sunroof, the car has everything!
My question is, even though the car passed it's MOT, when driving in the dark, the headlights seem to light up a lot of the lane next to the drivers side, but very little kerbside, and don't offer light in front over a very long distance.
If anyone has any ideas i'd love to hear from them
