I've been reading threads on how to go to a dealer to have your car reprogrammed to "present" for the xenons that I had installed. Every dealership I have called will not do this and I went to a Mercedes tech place and was told there is no such module. I'm looking for a place in the Chicagoland area that would be able to change this setting so my xenons won't flicker anymore. I have an '02 ML 500. Any help would be greatly appreciated!
