Learned today that the headlights have a one year factory warranty. Not sure if that covers the labor it takes to install them. Check with your dealer, before you take the car apart ;-) There are two Hex screws at the top and one to the rear in the engine bay this one only need to be slackened since it is on a slide. The complete unit slides forwrad and out of the car. It would be better to discinnect the plug but i can not see how this is done can anyone answer this?

Press and hold the reset button on the right side of the instrumnet cluster till it displays release and hold another 3 seconds. release and your done. It is a combination of button presses using the time and odometer reset buttons. I need to do my own but don't know the sequence. There is a publication with them in, which most decent service stations/garages should have. This process is for a 2001 and newer. (w203) This is the process for the older ones The car Key must put into the second Position. (Not starting Position, but all Lights on) Then you must double push the little "0" Button. (You have only 2 Seconds to do it)

Then take the Key in Position 0.

Then Push the little "0" Button and hold him.

Then again take the Key on Position 2 with holded "0"-Button.

After ca. 10 seconds, it makes a Beep and the Service Meter is resetet.
