Hi,

Recently, I bought a pair OEM W211 xenon headlights (with only one
ballast on the bottom) and tried to install them on my 2007 E350
which is equipped with halogen headlights.

I found my car only got one wiring harness for the halogen headlight,
but the new XENON headlight got two connectors.
so I just connected the only wire to the XENON headlight, and
brought the car to MB dealer to program the ECU. The dealer tried
it for an hour, and they told me it's not working without another
wiring harness.....

Has anyone upgraded their W211 from halogen to OEM XENON?
Any good MB mechanic or dealers know how to do it? (I am in Bay Area,
California)

Please share your experience.

Thanks and have a nice Thanksgiving weekend.

I just installed OEM xenons as well but they turn on for a split second (the driver blinks then the passenger side). Did you find a solution? Any help is greatly appreciated.

you have to have them programmed in star to xenons=present, and go into the menu and change the lights to constant I think in the menu on the car.

Do some research youll find that issues fixed.

As for the OP 1 balast for 2 lights? and one connector? Do all the lights work?
