2021-2022 Audi Models Instrument Cluster Noise TSB

Owners of certain 2021-2022 Audi models may notice an Audi instrument cluster noise, specifically rattling or vibrating sounds coming from the dashboard area around the instrument cluster. This issue is detailed in Technical Service Bulletin (TSB) 90 21 98 2059335/2, which supersedes an earlier bulletin, 20-45, dated April 24, 2020.

Symptoms

The primary symptom reported by owners is a persistent Audi instrument cluster noise. These noises are typically described as rattles or vibrations emanating from the area where the instrument cluster is installed. The sounds are often more noticeable when there are relative movements between parts directly applied to the instrument cluster.

Technical Background

According to Audi, parts of the dash panel can resonate due to vibrations from the engine or the road surface. Components such as air ducts/vents, the control module holder, MMI screen, trims, covers, wiring harnesses, cable guides, or the dash panel itself can be the source of this Audi instrument cluster noise. When these parts experience relative movement, they can create audible noises.

Diagnosis and Repair Procedure

To address the Audi instrument cluster noise, technicians will follow a specific diagnostic and repair process:

1. Instrument Cluster Inspection: The technician will first remove the instrument cluster. It will then be shaken in all directions to determine if the noise originates from the cluster itself. If no unusual noise is heard from the instrument cluster when removed, it should not be replaced.
2. Dash Panel Area Check: The dash panel area will be thoroughly inspected for any loose bolts, brackets, cables, or other components that may be vibrating. Common culprits include air ducts, vents, and wiring harnesses.
3. Securing Loose Parts: Any identified loose parts will be secured, fastened, or treated with felt tape to dampen vibrations. If necessary, certain vibrating components may be replaced.

Audi has implemented improved noise dampening in production to mitigate these issues in newer vehicles.
