2021-2022 Audi e-tron Energy Consumption Display Low TSB

Symptoms

Owners of 2021-2022 Audi e-tron models may notice that the "average long-term energy consumption displayed in the instrument cluster is implausibly low." This issue typically manifests after approximately 3,000 miles of driving.

If the long-term memory is reset, the energy consumption display will temporarily show correct values. However, the problem will recur once another 3,000 miles have been driven, leading to a consistently low reading for the Audi e-tron energy consumption low issue.

Diagnosis and Trigger Conditions

The root cause of the inaccurate display is a software malfunction within the instrument cluster. This software error causes the values shown to be incorrect, specifically impacting the average long-term energy consumption.
