Ok so I have fixing all the problems to my recently purchased 2005 c55 and this is one of the problems left.. They are stock bi xenon headlamps..

My symptoms include-
Driver side lamp will occasionally flicker..
Driver side and passenger side will go OUT.

Any help on this problem would greatly be appreciated..

probably a bad ballast (but could be igniter) on the driver's headlight.
you have to pull the headlight off and swap the ballast that sits on the bottom of the headlight.

i went through the same thing
