You more than likely have a serious pressure air leak in the system. More than likely one or more airbags.

Mercedes-Benz... | Answered on Feb 01, 2018

it could very well be just the seat belt latch but you really need to see what codes are being set because there could be other issues as well. You need to get the SRS system scanned. I do not know if the seat will need to be removed. If the latch is attached to the seat itself and it most likely is I'd say yes the seat will have to come out. Very easy to do. Move seat in full back position to get front bolts out and full forward position to get rear bolts out and then carefully disconnect all electrical connectors going to the seat.
