OK, I have tried everything in the manual about resinking my sunroof, resetting, adjusting but its still touches closed and partially reopens... Someone must know what is wrong and how to fix it. I even tried checking it with the key fob in summer mode where the windows open seat coolers come on but the moonroof will not open. Something is going on that is not such a simple fix. The dealer says there is a sensor band around the glass roof causing the problem and the glass roof needs to be replaced, come on... lets fix the problem.

clean and lube sunroof tracks. Use only MB sunroof lube.

If that does not work, try this.

Open all the way, then activate the auto close, but immediately stop it, then activate the auto close.

There are 3 or 4 presets for a partial open. If you unset it all the way by opening by holding the switch, then closing by holding the switch, it will use the first place which is slightly tilted.

I'm a little confused by this post, could you elaborate on it?

Annual problem?

"Moonroof will touch closed and partially open again..
Next project!

Sunroof will only touch closed and partially open 3-4". To close it I have to play with the close button. Is there a roof sensor to replace or is it a case where I will have to replace the moonroof because the sensor is rapped around the glass? I have tried to reset it and adjust it as per the manual and nothing works. To check it I have tried the fob in the summer mode and the roof will not open. The windows and air cooled seats work but not the roof.. The dealer told me I need to replace the moonroof as the sensor is around the glass, obviously very expensive and I want to be sure!

Sunroof paste (lubricant)

Ok, It looks like I need some of this lubricant for my sunroof tracks. It only come in large quantities from the dealer (part number A 001989 14 51) does any one have some I can buy in a smaller quantity?

Sure you tried resynch?

Are you sure you did the resynch properly, my 2003 s430 did the same thing when battery was changed.


The fix in the manual says this :

switch on ignition
push the roof switch in UP direction until it is raised at the rear (ie: just vented, not open)
hold switch for 1 s
roof is now synched.

Needs the test equipment on it as it now sounds to be faulty.
