2024 Q4 e-tron 45 wrong soc

Bug Reports

My 2024 Q4 e-tron 45 shows a deviating SoC value via the OBD dongle. Using OBD PID Editor, I optimized the value so that it almost matches in the upper 50%. However, from 50% upwards I still get a difference of about 3%. I used the following equation: A*0.4425 - 7.7.

I have now found out that the car also outputs the SoC value from the dashboard via OBD. In CarScanner this is the sensor: Remaining service life of hybrid battery (see screenshot which is in german:

verbleibende Nutzungsdauer Hybrid-Akku).

Is it possible to use this sensor for the SoC instead?

Where does this happen?

    Yes, but it is possible to read the exact SOC via OBD. If this option is available, I would prefer to use this value.

    Hi

    It’s normal to have a difference of 2-3% for the SoC when using an OBD.
