It doesn't matter. It's the airbags. Postpone a mod. The entire crush of the body and performance of the seat belts is predicated on the airbags deploying at changes in velocity of more than approximately 10-14 mph. The intent of the seat belts is to keep you inside the vehicle and positioned to benefit from the airbag deployment. Belts alone may not prevent serious injury to chest or head from impact. The absence of side impact airbags cannot be managed by structure alone. Without airbags, you and/or whomever is with you may suffer greatly in an impact. And, as you know about a potential failure of the airbags now, resulting injuries may be considered foreseeable and negligence on your part if you allow it to continue and carry passengers. Borrow the money if needed, but get this checked out.
I had the same problem, lucky i was under 50k and got it covered. This is what was written on my work order.
Client states SRS light comes on.
Cause: ELECTRICAL FAULT.
Belt buckle connected SDS and performed short test, found fault code 9B51 short to positive or open circuit in drivers front belt buckle. Clicked on guided test and checked for wiring fault. Found no fault in the wiring. Removed left front seat to remove and replace faulty belt buckle. Erased faullt codes after repairs and roadtested car.
541011 short test, perform
541012 test program - after short test perfom
911516 Lock for seatbelt on driver's seat replace.

Also when I had SRS light on also the red airbag light was on. both were fixed under warranty. I guess once they fixed the SRS problem airbag light were automatically fixed as well.
Hope this helped and even if you are out of warranty you should get it fixed. Good luck.

Well considering the fact its only 3yrs old and this is not something normal like breaks, oil change, tires, and ect. This is a safety issue that I did nothing to make this happen. For all I know this could be a recall! Mercedes Benz has a good reputation and this is something that they should fix for me without a charge!

BTW, the seat belt buckle electrical contacts are part of the Restraint System and the German manufacturers have been having trouble with them since the '90s.
Personal experience.

I m driving a w204 c200k year 2008 with 65000 mileage.I have the same problem with the srs light keep on and the display show srs malfunction required.I send it to a mechanism,was told the electrical plate/board that control the airbag was not functioning and need to change it.it may cost me like 4k plus..please advise..thanks
Yesterday I drove on my normal route and noticed quickly that no gauges working and no turn signals working. I turned back home. Turned car off, then back on, then all gauges worked but got several warning signals like SRS, ABS faults etc. Then unhooked battery, then engine would not start. Waited about 1/2 hour then tried and it fired OK, but still getting SRS warning. Everything else is OK but this now. We did have a lot of rain lately, maybe wiring is wet? I don't see blown fuse. Any thoughts?
Just off work to go home and car wont start
The battery is dead
I tried few times to start and it didn't work
Now I got two massages messages on dashboard
One is
SRS Malfunction
Second one is
ABS and ESC currently unavailable
Help anyone
