Soaked SAM
This happens when water runs down the A-pillar guided by thick harness bundle into SAM's enclosure. SAM is in charge of managing the car power distribution.
Crazy SAM guarantees electrical grumblings.

Haven't tried this yet on my new car but in the past I've used weed trimmer string. Feed it down through the drain line from the top of the sunroof. Usually you'll find 4 drains, one in each corner.

reproduce issue before attempted fix...
Is it the sunroof drains that are plugged or the something else leaking buckets inside (roof seem or windshield seal).

before you go ahead and snake through the drain ... first try to reproduce the problem with a quart of water. Is water not coming down at all vs. reasonably well??

This problem has been discussed on this forum, the W212, and W211 forums. One might think that after 20+ years, Mercedes would have devised a solution to eliminate the problem.

there’s a few spots in mine like the plastic box over the battery
Did they specifically say where the drain is and what caused the clog?
Was it the sunroof? As the problem you are experiencing reminds me of another thread (GLC though) :
