How do I Reset Error Code SOS in a 2001 Mercedes Benz C320
The Mercedes-Benz C class was once known for its reliability, but since the merger with Chrysler in the 90s, Mercedes as a whole has lost much of its engineering reputation. To that end, many of the 2001 C-class cars have endemic electrical and mechanical faults; the SRS fault being one of the leading issues. SRS stands for the supplemental restraint system and is supposed to pre-tighten the seat belts in the event of a crash, but in practice serves only to require periodic trips to the dealership to fix its faulty sensors.There is, however, a way around this.

Buy a Mercedes-Benz code reader from a website, there are many available. Make sure the code reader has a 16-pin OBDII standard socket port. The 16-pin port is what the diagnostic port on the C320 uses. 32-pin readers can be used, but an adapter and rather complex software is needed. It is simpler and cheaper to just get a 16-pin reader. No batteries are needed, as the code reader draws power from the car itself.
2Start the car and wait for the reader to flash the name of the code reader, then press the "Read" button. It will be the green button to the bottom left. It will flash the error code three times; after the third time, press the erase button. Depending upon the model of code reader, you may have to press "Erase" after every code or only once for all the codes.
3Disconnect the code reader and turn off the car. Then turn the car back on and replug the reader to check to see if the erasure took. If it has, you are done; if it has not, you will need to replace the SRS sensors themselves, which only a Mercedes-Benz mechanic can do.
