Hi guys,

See the picture where I insert the command in obd2 monitor.

The important part is to map the fuel level in ā€˜Settings->Units & Values->Input Mappingā€™.

The reason 012F does not respond is that 0100 is not responding. It seems like ATSP0 (automatic protocol setting) is not working with your adapter/car.

I do not know what the PID 0F12 is. Have you tried the standard PID for fuel level 012F?

But in general, if you get reply ā€˜NO DATAā€™, it means that PID is not supported by your vehicle. Usually that same info can be found from another, vehicle specific PID.

Sorry I made a mistake with the picture, the PID Is 012F, and I find ā€œNO DATAā€ .
Please could you give me other PID for Mercedes so I can make some test.
Thanks!!

Unfortunately we do not have a database of vehicle specific PIDs, sorry :frowning:
