Mercedes-Benz Sprinter sliding door preventive maintenance foam retrofit.

I watched the video from 5:00 onward. What does this piece of foam do?

Or rather, what preventative purpose does it serve?
Without the foam seal, debris or FOD as called in aerospace, "Foreign Object Damage" chutes thru a gap directly to the cavity below and doesn't take much to gum up the door cable track and thus the reason for the foam retrofit.

So, $13.00 bucks versus (wallet flush) whatever the expensive looking cable thingy costs, Plus labor to install.

I assume this is mainly a problem for automatic doors...
What about the soft-close door option?

I would assume all doors that have a 1/2 inch (13mm) gap running the bottom length of sliding door?

I installed the factory foam but any equivalent dimensional closed-cell foam will substitute.

Right, but do all have that track/chain?
I guess for those who neglect keeping the area FOD FREE will find-out if they have a track, and learn how much to repair. Bet it ain't cheap. Especially if on vacation and can't close door.
