2019 Audi etron fails to connect to odb dongle

Questions
I have a obdlink cx dongle. It works (sometimes) with the Audi etron 50, but my car is a 2019 etron 55. Every time I try to connect, it fails to read SoC from the car. CarScanner app is able to communicate with the car and reads the SoC.

    Hi,

    Please add more information such as;

    • Error messages if any given

    I could suggest to first disconnect the dongle from any other app (such as carscanner) before attempting to link ABRP.

    Unless you already have, please read this article;
