No SoC updates for Audi Q6 e-tron while driving

I use ABRP with Enode on my Audi Q6. The SoC updates perfectly when the car is stationary. But, during a trip, the SoC update does not work and aberrant values ​​come back.

For example, the car indicates a SoC of 70% and ABRP will update with a false SoC of 80%. Suddenly the SoC on arrival also becomes false.

I have to disconnect my phone (iphone), close ABRP, and restart the trip to find a good SoC. Is this an Enode problem? of information feedback from the car? Thank you for your help.
