    Hi,

    Which OBD2 scanners are able to read and display data such as fuel trims for a 2011 350 CDi Diesel?

    I have a cheap Bluetooth OBD2 reader and tried this with the Torque Android app and it can read a number of parameters, error codes etc., but although the app should display fuel trims, no data is recorded/displayed (the graphs are all just flat at zero).

    I have borrowed a Carista Bluetooth scanner and also tried a different Android app (Car Scanner), but again no fuel trim data.

    Can anyone recommend a (cheapish) scanner and/or software (Windows or Android) which will show Fuel Trims for this car.

    thanks

    David

    You could try Carly for Mercedes.
    With their OBD2 adapter that can read quite a lot of MB stuff.
