What I have heard is the xenons are plug and play BUT your warning system telling you there is a bulb burned out will not recognize the xenons and therefore will falsely indicate there is a bulb out all the time. I have heard the dealer needs to reset with the SDS to tell it the car has xenons. I do not know if this is absolutely the truth, but it is what I was told when I inquired about converting mine.

FWIW My c43 has xenons and they are no better than the halogens in my E300 in my opinion so I am glad I never converted them.
