On the driver,s side under dash there is an audible relay called a seatbelt warnung relay. I would recommend replacing it because by just unplugging it you may experience interior lighting issues. It is a very common problem with that era of mercedes. If you remove the under dash you will be able to locate it by sound with the key on. Unplug it with the key off.

The driver side seat belt buzzer keeps ringing even with the belt buckled


Find and disconnect the seat belt buckle connector. short the two wires together on the harness side with a paper clip. If the chime/buzzer quits, the problem is in the buckle assembly. If the chime/buzzer is still going off, the problem is some where in the wiring or module.

Seat belt warning buzzer won't stop even when the seat belts are connected.


The seatbelt connector could be disconnected. Follow the wiring that comes out of the buckle. You would see this wire close to the cars floor/carpet. Hopefully the connector is pulled out otherwise wiring could have snapped. If the wiring looks good. You may need to clean the buckle as dirt could be preventing the switch from going off.
