2020-2022 Audi e-tron Charging Notification Issue TSB

Symptoms

Owners of 2020-2022 Audi e-tron and e-tron Sportback vehicles may observe an unusual behavior related to their vehicle's charging process. The primary symptom is receiving "multiple push notifications on mobile phone stating that charging target has been reached" via the myAudi app. This occurs even as the vehicle continues to charge.

Simultaneously, the vehicle's wall box may cycle power on and off. The LED module on the charging socket will also show a sequence of green (continuous), white, and green (pulsating) lights, indicating an intermittent charging status. These visual cues and app notifications collectively point to the Audi e-tron charging notifications issue.

Technical Background

Audi has identified the root cause of these persistent Audi e-tron charging notifications as a software issue. This means the vehicle's internal programming is misinterpreting charging states or incorrectly triggering notification alerts to the myAudi application.

Repair Procedure Summary

To address the excessive Audi e-tron charging notifications, a software update is available. This update is part of Audi's campaign 93N1. The repair involves updating the vehicle's software to correct the logic that triggers the charging target notifications and manages the charging socket LED behavior.

Technicians are instructed to first reproduce the customer's complaint to ensure it aligns with the conditions described in Technical Service Bulletin 93 24 89 2074706/1. Once confirmed, the software update from campaign 93N1 can be applied. This update is designed to resolve the inaccurate and frequent notifications.

Important Warnings for Owners and Technicians

Audi has provided specific guidance to ensure the correct application of this service bulletin:

• "Try to reproduce the customer complaint (based on the description/cause of the issue), so that it can be clearly assigned to this TSB. The following repair must only be carried out if all the criteria (model/type, chassis number, engine/motor and gearbox code, PR number(s), part number, software version, code etc.) apply exactly. Otherwise, this solution will not eliminate the problem, and repeat repairs may be necessary. In such a case, we may reject the warranty claim and redebate the parts."
• "Please always process all open campaigns before you apply any other TSBs."

These warnings emphasize the importance of proper diagnosis and adherence to the specified conditions before performing the software update. Incorrect application may lead to unresolved issues or warranty claim rejections.
