2021 Audi e-tron Range Display Implausible TSB

Frequently Asked Questions

What does 'implausible range display' mean for my Audi e-tron?

An implausible range display means the estimated driving range shown in your instrument cluster is inaccurate. It might show a full battery but a very low range (e.g., 140 miles or less), or the range might decrease rapidly and not increase as expected after charging or driving.

What causes the Audi e-tron range display implausible issue?

The issue stems from a miscalculation within the high-voltage battery regulation control module, identified as J840 (address word 008C). This miscalculation leads to incorrect energy consumption readings, resulting in an inaccurate range display.

Are there any specific fault codes (DTCs) associated with this problem?

According to TSB 2060814/3, there are typically no relevant Diagnostic Trouble Codes (DTCs) stored in the high-voltage battery regulation control module (J840) when this range display issue occurs. This means the problem often won't trigger a warning light or a standard diagnostic code.

How is the implausible range display issue fixed?

The repair involves a diagnostic process to verify energy consumption values. If these values exceed a certain threshold (1.8 mi/kWh), the high-voltage battery regulation control module (J840), also known as the Battery Management Control Module (part number 4KE915233*), is replaced by an authorized Audi service center.
