Dear All,
Dear @Leetom

I read it's a common issue that the sky window makes some noise when driving on Bumpy Roads after time.

It had been fixed a few months ago, they greased it I think, at Mercedes Benz, but now it's back again. The sound is so annoying!

Don't want to go back to Mercedes as they charge quite a bit, can I do it myself, fix the sky window on my ML550? Anything helps, and what would I need to purchase in order to fix it myself?

Thanks so much!

 

Mine has not developed a rattle. I have a Panoramic roof, which is be different than regular sunroof (I dont recall if they sold regular one or not). Maybe get up there and tap on it with your fist to see if u can find rattle. Might need new guide pins if they are warn.

 

Amazing, as always @Leetom your quick replies are amazing! Yeah this morning it was gone, but will come back again, those sky windows eh, I mean I have a sliding panoramic roof, too, I think on the ML550? LOL

 

I am not familiar with the panoramic sunroof on the ML550, but those in the W211, and W212 can be noisy when the interior screws/bolts are loose. Nothing you can from the outside, but loosen the headliner, drop it a bit, and tighten them again.

Does it sound metallic, or plastic rattle?

Here is a video for the W212, hope it helps at least to differentiate if the noise comes from outside, or inside.

 

When I had a pano roof on my first W212 E Class I used a product called Krytox. It is expensive but it works all the time.

 

Hey there @juanmor40

Thanks so much, definitely can't work on it as much as I am not a great tool guy !

It's more like a "glassy" sound, not really metal at all, maybe more plasticy, but would say 'glassy'-plasticy sound. I think Mercedes put some grease on it and then the sound was gone. I wonder what grease I should buy and apply?

 

This is the one, you need to find some at a decent price

and a video for lubricating the panoroof for the W204 (all the same anyways)

 

Cool @C280 Sport that might be the solution!!!

Grease, Krytox, eh?

There are so many options at Amazon, which one is right oh and hey:

-> Can I buy it at like Home Depot or Canadian Tire?

 

..Noooooo.. Those usually collect dust, dirt and it will create a mess later on.

 

HEHEHEHE!!!!! OKOKOK I see it's a Mercedes Benz product, maybe a good idea, indeed!

Maybe I can buy this directly from Mercedes (car dealer).

Appreciated @juanmor40 - really appreciated, will have to get it here in Canada.

 

See updated post above.

The original tub cost @US$100, and it is about 0.5Kg. You may need to lubricate all your friend's cars for years to run out of it. That is why some people, part it into smaller containers @0.5 oz and sell it to those who need only a bit.

 

Oh wow need a small one then, yeah!

 

Please do not do that of putting the tub on top of the paint. That is how scratches start, by a small mistake.

 

Thanks so just on the metal and plastic and not on the paint ?
