So I bought a 03 C320 stuck in limp mode and havent been able to fix it because the OBD2 sensor wouldn't power on. I've narrowed it down with some investigative work and this is what i've found so far.

I pulled out the entire ECU to check it, had two bent pins that I fixed back and checked the OBD2 sensor again with no results.
Checked the continuity of the OBD2 pins. 7 and 8 had 12 volts, but 16 did not.
So i'm currently trying to check the resistance/continuity from the DLC to the SAM module pin 11.

Unfortunately i have limited knowledge of these vehicles electrical systems and not sure where pin 11 is located in the SAM module.
Can anyone give me any additional information on where to look and a SAM diagram that could possibly break it down?
