2021 Audi Instrument Cluster Noise TSB

Audi has issued Technical Service Bulletin (TSB) 2059335/1 to address customer complaints regarding noise originating from the instrument cluster area in various 2021 models. This bulletin provides diagnostic and repair procedures for technicians to resolve these irritating noises.

The TSB explains that vibrations from the engine or road surface can cause parts within the dash panel, such as air ducts, wiring harnesses, or the dash panel itself, to resonate. These vibrations can lead to audible noises, often perceived as coming from the instrument cluster, particularly when there are relative movements between directly applied parts.

Symptoms

Owners of affected 2021 Audi vehicles may experience the following symptom:

• Noises from the installation area of the instrument cluster. This can manifest as rattles, squeaks, or other unwanted sounds that seem to emanate from behind or around the instrument panel.

Fault codes / DTCs

This Technical Service Bulletin does not list any specific Diagnostic Trouble Codes (DTCs) associated with the Noise from the area around the instrument cluster. The issue is mechanical in nature, related to vibrations rather than electronic malfunctions that would trigger a fault code.

What the service bulletin says

TSB 2059335/1 outlines a specific procedure for technicians to diagnose and resolve the instrument cluster noise. The primary goal is to determine if the noise originates from the instrument cluster itself or from surrounding dash panel components.

1. Instrument Cluster Inspection: Technicians are instructed to remove the instrument cluster and shake it in all directions. If no unusual noise is heard from the cluster itself, it should not be replaced.
2. Dash Panel Area Inspection: The dash panel area must then be thoroughly checked for any loose bolts, brackets, cables, or other parts that could be vibrating. Any identified loose components should be secured, fastened, felt-taped, or replaced as necessary.

Audi has also implemented improved noise dampening in production as a solution for this issue. Warranty claims related to this repair will be processed using specific labor operations, including 9025 19XX for removal/installation, 9025 0199 for checking the instrument cluster, and 7018 0199 for checking the dash panel. The damage code for this issue is 0020, and diagnostic time 0150 0000 may be claimed.
