You have to remove the overhead control unit (front dome lamp assembly) to gain access to the sunroof motor(link below) You can then put an allen wrench/socket into the drive motor for the sunroof and turn to close. This works if the sunroof motor has failed. If the problem is the switch, you might get lucky by pointing the key at the IR pickup on the driver's door handle and holding the lock button. That should close all of the windows and the sunroof. Mercedes 211 overhead mirror removal

Sometimes if you disconnect the battery, the sunroof will lose its automatic operation. In order to reset it, you will need to manually cycle the sunroof all the way open, all the way closed, and all the way vented and closed.

Try it both ways and check , but do not apply too much pressure

in the trunk on the drivers side there is a plastic bolt to turn, in your tool kit should be a socket thing that should fit it to turn it.

Some customers may comment that the sunroof will no longer respond to the control switch while in a vented, partially opened, or fully opened position.

If the motor is stuck, you can probably hold the switch to the forward position, and smack the roof. This may allow the motor to start working. I don't think there is any way to do it manually.

Hi, you will have to get your car pluged into a Diagnostic computer with MB software.
It may just be a case of reseting the system.
But if it comes to the worst one of the SAM (can system) units has gone a little faulty & can only be replaced & reprogramed using MB computer system at a Merc garage or a top Diagnostic garage.
