retrofitting xenon headlight
Will replacing the original halogen headlights with 35W xenon headlights trigger the blown bulb warning?
any experience with this?


If You are just swapping bulbs...It should be ok as long as the replacement bulbs are a matched set ..as the Headlight control unit measures resistance
consider this as an alternative, if you have difficulty getting a dealer to code
this for your car. some dealers may refuse.
I haven't broken free of the local area up here to go on the road and borrow a buddies SDS that has all the bells and whistles.Cheaper that way.

depends primarily on the model of ballast used vs the bulb itself. case in point,
I have a E55 in a Depo, using a Hella gen3 ballast which does not require any
capacitors, resistors, or dealer SDS. no bulb malfunction code.

OK, so I'll play safe and add a cable to connect a resistor/capacitor module, then we can connect that if he gets problems...
