sorry but i couldn't find the answer to this... is the moonroof capable of closing on one touch like the windows? mine has always closed half way and bounces back (almost like a safety feature). I know with the Range Rovers, you'd just have to "reset" the window/moonroof, but I can't figure it out. Have had the car for 1.5 years, time for mods now.

Your vehicle is equipped with express open & close you may need to clean/lubricate for proper operation if you want instruction sheet PM email address.

so what happens is, if it doesn't close all the way on "one-touch" in this case "express" close, and I hold the button down, it will close.

You think its a lubrication issue?

Yes.

Thanks Konig. Any suggestions on what to lubricate the rails with?

Thanks Konig!
Konig stated MB recommends grease part # 001989845110. He also stated white lithium grease is OK but as sparingly as possible. No WD40.

I have an '07, it does the same thing. My buddy has an '06, same issue. Seems to me that it's either a common issue that Mercedes should have addressed or some type of very annoying safety feature. Considering that I always ride around with an arm, leg or sometimes my head hanging out of the sunroof it's saved me quite a few times haha..
