Hi chaps.
Had a search on here, but can't seem to get anywhere.
The drivers side dipped beam has packed up on my 2006 220d sport.
It actually packed up in mid summer, but due to the fact I don't do a lot of night driving, and it was summer I didn't get it sorted.
Now winter is here and the mot is due, I need to fix It.
The problem started when using the auto function, the drivers side light would turn off randomly, then when switching from auto to manual it would ignite.
The problem got worse till it wouldn't ignite at all.
I have purchased a pair of replacement bulbs, but on fitting the new bulbs the drivers side still won't ignite.
As I also have an issue with the drivers headlight fogging up with condensation I decided to remove it to check it out.
On inspecting the ballast fitted to the underside of the lamp unit, it looks rather corroded and the paint on it is bubbled up a lot. So I presume the ballast unit is shot. Does anyone else agree? Can you test the ballast output to check it works?
Does anyone know how much the main dealer will charge to supply or fit a new ballast?
If not the ballast, is there an igniter for the bulb?
Also on the subject of condensation, are there supposed to be any covers on the 3 plastic projections the stick out of the rear of the lamp unit? I only ask as I found what looks like a plastic cover behind the light unit, inside the inner wing. It is semi clear plastic with a disc of foam in the bottom, and it fits nice and tight over the projection on the back of the head light.
Sorry for the long post, but it takes a bit of explaining, and I am not very well educated in vehicle electronics relating to hid lamps.
Thank you for having the patients and reading my long post.
Matt.
