"Sound encapsulation" was only used on the 190D 2.2. The 2.3 has a partial "belly pan" under the engine for aerodynamic management. It usually has to be removed to change the oil, so I'm sure there are many cars running around without it if the owners have their oil changed at Jiffy Lub. The pan is secured with six 6 mm sheet metal screws with 10 mm hex heads.
