Well, update on this. So, it seems the first unit I bought did not work. Not sure why, but after further inspection, it looked like it was the right unit, but did not have the exact part number. It fit perfectly, same circuit board configuration, but just didn't work. I went ahead and bought a new one from ECS Tuning, and it looked like an OEM part, same part number. Installed it and voila, it works. However, it looks like it needs to be coded to factory, but the good news is that I can now read from both units. I read somewhere that if module in the left is not working, neither unit will work and you won't be able to read from either. I will SG_Codieren and post results here.
