On the subject of leaks and drains, it's spring, and my entire neighborhood has young maple trees everywhere. this means, many small "propeller seeds" are getting on (and some in) my car daily. I have been vacuuming out near the windshield wipers but I think I'll be doing something more drastic soon. I flushed out the "side drains" last year and they were OK.
Be sure to check the rubber flap coming from the passenger side windshield edge to the whipper cowl. There is a drain on the cowl at that point. Age and weather can deteriorate the rubber where it no longer directs water to the drain. The water flow off the cowl past the drain and finds its way into the cabin. I glued a piece of weather stripping used for house doors to the cowl to fix that problem.
My experience is with a 2011 E350

Do you have couple pics of this MB favorite detail?
This is what's used to channel water to electricals.
I've looked at this drain once and could not find that trap
Here is a picture of the drain. You can see how the rubber I am holding is cracked and actually part is missing. As water runs off the front window it should drain into the vented area shown. The damaged rubber flap stops it from going past the drain. To stop the flow from going past the drain I glued the textured rectangle piece you see by the drain. Located at bottom of windshield on passenger side.

Nice one, thank you!
How is the driver side doing...
also one rain away from flooding electricals?
The driver's side cowl drain is a different layout. I'm not experiencing any issue there. I found this problem while trying to track down a problem with my display for the Command system. My problem is the screen on the command system. The audio works fine, just the screen is black also no picture from the backup camera.

2011 to 2025 = 14 years.
The rubber weather strip you are holding , is it also "sticky" ? Aside from the cracking.
It seems more sunlight damage , aside from 14 years of age...yes ?
I too been wondering how long it will last for , if for a sun protected garaged car.
My issue is best viewed in your second picture. You can see the drain grate next to where the wiper attaches. My damaged part comes from the edge of the windshield down to the cowl. Yours looks in good shape.
