Hi guys, I have some problem with fuel level in my Mercedes C 220 of july 2017. I change in: obd2 fuel level but nothing the level is always zero. See the picture where I insert the command in obd2 monitor. Could you help me?

Did you check this post? [http://realdash.net/forum/viewtopic.php?f=56&t=1259&sid=da00b7c1416407ee99098eb0d6138bfc](http://realdash.net/forum/viewtopic.php?f=56&t=1259&sid=da00b7c1416407ee99098eb0d6138bfc) The important part is to map the fuel level in ‘Settings-\>Units & Values-\>Input Mapping’. 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. ---

Thanks for your reply but see the picture. Could I try to make other test? ![IMG-20210423-WA0003.jpg](https://forum.realdash.net/uploads/default/original/1X/449475e732fe4c574d3a7ca642e71a64ca52dc4c.jpeg) ---

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 ‘NO DATA’, 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 “NO DATA” . 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 ☹
