switching headlamps..
Is there anyone here that have tried that on a S class (w220)?
i have done it so far, but now i can not get the xenon to light up. it comes with errors.
it is a EU model, S400L (cdi) have bought some look a like, think they are made on the same fab. as the originals, and have switched on all the cables etc. from the old one.
is there something that tells the computer in the car, that it have been off, and needs to be turned on again or something like that?
any suggestions would be appreciated

kind regards
Flemming
