He called these the pants. First thing you need to do when you get under your car is "take the pants off"...




Two of the plastic shields you showed and the steel one ( most important)
These 3 will not protect rodent entry. Rodent can enter from near suspension arm side.

In the photos above the first one is the front most tray, the second is actually the tray that goes over the transmission pan. They look similar to the W204.
Mine are all beat and damaged, ran right over a large street sign that had blown over during a storm. I havent bothered replacing them yet. I have however replaced alot of the metal clips and screws that mount them to the car. The threads of the screws rounded away and wouldnt hold it secure. I used both Genuine Mercedes and Febi brand and they both seem the same. Then for the tray over the transmission there were two different style clips that press up into the body, not sure if the W212 is the same.
The torque spec for the undertray screws is 12.5 ft lbs.

Looking at the pictures in OP’s post the edge of the second shield has only two holes when it should have four like the first shield has.




Info i'm looking at is for W212 with M273 but should be similar to M272.
I flipped the 2nd photo in the 1st post.
