RE: Hid conversion, "xenon = present"
I don't know a lot about Mercedes' lighting system as I'm a newbie myself.
From my experience though, I was helping a friend of mine to install one of these HID kits to his RAV4.
In Canada, most vehicles are equipped with DRL, and RAV4's DRL system is actually using the same bulb with main headlight with half the power. So when he starts the car, disenggage the parking brake, the light would then flicker and turns off as the ballast didnt receive enough power to power up the HID. The guy who sold the kit told him to disable DRL by taking off the DRL fuse, but we couldn't find it so I guess the DRL cannot be disabled.
The solution, he would start the car, turn on the light first, then disenggage the parking brake, so then the ballast get enough power to power up the light before the DRL kicks in. The lowdown though, if you turn off your light, in order to turn it back on, you have to turn off the engine, and start over.
This was keeping me to retrofit my grand cherokee's headlight cause my GC also use the main headlight for DRL.
I'm not sure about Mercedes lighting system/or if your car is equipped with DRL. But if your car has DRL, maybe this was the case.
If your car has DRL, maybe you can try turning on the engine, then turn on the light before you disenggage the parking brake (I'm not sure if the parking brake is the "switch" to turn on the DRL in Mercedes car, but the idea is turning on the light before the DRL would kick in).
I hope this help or at least shed a light on the problem.
