Hi Guys,

I need your help. I have a MB B170 (W245) and had a transmission error. I purchased a new one and installed it. I am however getting sensor error problems - see below.

Errors:
P0793 Secondary output Sensor (common failure)
P0722 Output RPM Sensor (common failure)
P2731 Impermissible closing of hydraulic clutch
P2722 Impermissible closing of hydraulic clutch

Does a new module require programming. If yes, then what is the error you get before programming.

Regards,

Fredrick Kamau.

For your Info, a new one does not need SCN coding. Just do data swap and pick the right variant coding. In my case it was R210.
