Symptoms

This technical service bulletin highlights several symptoms owners might observe. These include audible noises, warning messages on the instrument cluster, and functional failures.

Common symptoms reported are:

• "Noise from front door trim panel while driving"
• "Low coolant warning in cluster", even when the coolant level is correct

Fault Codes / DTCs

Several specific Diagnostic Trouble Codes (DTCs) are associated with the issues described in TSB 10247144. These codes help technicians pinpoint the source of the problem.

Diagnosis and Trigger Conditions

The TSB indicates that these faults can manifest under various driving conditions or during specific operations. For instance, a 'Low coolant warning in cluster' might appear despite correct coolant levels, suggesting a sensor or electrical issue rather than an actual fluid shortage. Similarly, issues like the "charge handle doesn't release" or "vehicle will not charge" point to problems within the charging system, which can be critical for electric models like the Audi e-tron. An Audi e-tron multiple faults situation often requires a comprehensive diagnostic approach to identify all underlying causes.

Repair Procedure Summary

While this communication identifies common issues, it serves as a general advisory for technicians rather than detailing specific repair steps. It is intended to inform service personnel about recurring problems that may not have straightforward solutions or require specific diagnostic attention. Addressing these concerns typically involves thorough inspection of the implicated components, such as the front door trim panel, cooling system sensors, fuel system, window regulators, air suspension system, charging port mechanism, belt tensioner damper, and wheel speed sensors. Proper diagnosis using manufacturer-specific tools is essential to resolve these various faults.

Owner Action

If you experience any of the symptoms or warning messages described, especially if your 2021-2024 Audi e-tron exhibits multiple faults, it is recommended to schedule an appointment with an authorized Audi service center. Provide them with a detailed description of the symptoms and any warning lights or messages you have observed. Technicians can then use this TSB and their diagnostic tools to accurately identify and resolve the issues affecting your vehicle.
