For the SRS light, there is a common issue with the harness in the steering column. There is a factory fix where you install a longer harness. BTDT.

And, if one sensor goes out, it can trigger several malfunction codes. In my case, the right front wheel sensor went out, and I lost ABS, cruise, and something else..... all needed the wheel speed input.

I have access to the MB diagnostic system, which is probably a necessity if you own one of these cars and want to do it yourself.
