2014 E350 4matic with sports package.
I've been changing oil a few times since I've had the car.
Every time I can only extract about 6L instead of 7.5L(my car had +1000ml oil offset)
So today I decided to go the old school oil drain.
And.......
WTF? There is no oil drain plug anywhere to be found.
The oil pan looks ridiculously small too.
I did some research and couldn't find anything at all.
Videos on youtube all have a nice oil pan with plug on side.
and the oil pan on my car looks like this:



This is a stock photo from here:

seems 4wd has different oil pan than 2wd.





If there is truly no drain plug I don't mind taking the lower pan off and drill a hole and put a screw on it.
But before doing that I better come here and ask if any one has been in the same situation.

I also twisted off the 'nut' in red circle thinking it might be the plug.

Seems it doesn't do anything?

EPC doesn't show a replacement for the inspection plate you removed. I can't help you with the screw that you twisted off either, I don't know why it is there. I was just under my car yesterday draining my oil and the drain plug is #20 on the sketch which is on the drivers side.

Great exhibit.

The nut / hex circled in red above to help remove the metal pan. Take one of the removed bolts - thread it into that hex and it will bottom out against the aluminum - breaking the seal of the metal pan. It's better than hammering a screwdriver or wedge and damaging either part.

Kjb55 is correct MB instructions: Insert a screw into the forcing bore (1b) to pry off the oil pan bottom section (1) from the oil pan (2) and use the assembly wedge to release it from the oil pan (2). Only pry off oil pan bottom section (1) with the screw from the oil pan (2) until the assembly wedge can be pushed between the sealing surfaces. The oil pan bottom section (1) and the sealing surface of the oil pan (2) will otherwise be damaged. If oil pan bottom section (1) cannot be loosened from oil pan (2), heat oil pan bottom section (1) in area around sealing surfaces using hot air gun.
