W204 2013 sunroof won’t close
I could hear the motor going but no movement on the sunroof itself.
If you do some research, sunroofs on W204 have this chronic issue where the gear that the sunroof motor uses to drive the sunroof on the rails shatters and then the motor spins freely, without moving the sunroof.
Replacing the gear itself is an easy DIY and you can find some threads about it here or videos about the replacement on Youtube, by looking up something like “W204 sunroof gear replacement”.
