Underbody Cover Replacement
This was a pretty straightforward job, with shipping both panels were under $300.
Put the car up on ramps.
Besides a couple of plastic expansion pin anchors, these are what is used to attach the panels, 8 and 10mm sizes.
There's also a small torx screw at the rear of each panel.
I panicked for a few minutes because the new part numbers had been updated as compared to the panels I removed but they were the right parts.
Drivers side wasn't too bad but still had a couple of rips, not that visible here but from below pretty obvious.
Passenger side was pretty trashed.
Didn't take an underbody pic but the new panels fit perfect and look so much better under there. I also noticed that with the rips the old panels acted like scoops for dust and dirt.
Easy DIY.

I actually had this done under warranty when I had my E class: it was delivered with a torn piece of felt underbody........wasn't a big deal, but the dealer blushed lol

I got a new one on line for $136 shipped. At least all my fastener and bolts was still there. It was an easy swap!
