Ummmm. Is it important to know (i.e. what is the problem, or what are you trying to achieve), or is it purely an academic question?

If the former then members may make the time to research this and respond. If the latter, then ......

Some holes are used during the manufacturing process - e.g. to give once off access to a part, or to a bolt, and are then plugged. This might be one of those - I don't know.

Another explanation might be that there is an identical hole on both sides of the car. On a LHD car the hole on the driver's side is not used but on the passenger's side it is. And it's the reverse situation on a RHD car. That way MB only have to make one version of the relevant parts for both LHD and RHD cars, and fit a plug costing 5 cents to the unused hole.

Here is a photo of the identical hole (plugged) on the driver's side of my RHD car .... so opposite side to yours. Some weeks ago I was in search of a component of the anti-theft alarm system which is supposed to be installed here (if the car has this option fitted). This hole may or may not have something to do with this - I don't know.
