Does anyone know if there is any TSB for the pana roof making clicking/popping sound.
Some strange popping noise is coming from somewhere in the rear of the car.
Any suggestions to what this can be?

Thanks

probably just needs a little silicone on the seals. What does your dealer say?

I think MB dealers use Gummi Pflege like BMW dealers but some also use krytox for these types of noises. There could be other things wrong with the mechanism, however. Do you hear the noises when driving up driveways, where body flex would cause the sound or just in general? There are other areas in the rear of the car that cause noises, like the c-pillars, roof access cover for the rear lights, rear sunshade, rear cover for the speakers.

No DTB that I am aware of I, have shop foreman ride along for a test drive so noise can be identified.
