2021-2023 Audi Q5/SQ5 Front Power Window Noise TSB

Owners of 2021-2023 Audi Q5 and SQ5 vehicles may notice an Audi Q5 window noise when operating their front power windows. This issue, described as "The front power windows make noises when they are opened or closed," is addressed by Audi Technical Service Bulletin (TSB) 64 23 90 2064585/2.

This TSB, which supersedes the earlier TSB Group 64 number 22-82 dated January 8, 2022, provides a detailed procedure for technicians to diagnose and resolve the noise. The primary cause is often environmental factors leading to increased friction within the window system.

Symptoms

Owners will typically experience an audible Audi Q5 window noise or squeaking sound when the front power windows are either opened or closed. This noise indicates increased friction within the window's operating mechanism.

Technical Background

Audi has determined that the front power window noises are primarily due to contamination and dirt. These foreign particles can accumulate on the window and its associated seals and regulator components, leading to increased friction. This friction then results in the unpleasant sounds reported by vehicle owners.

Important Warnings

Audi has issued specific instructions to technicians regarding this issue:

• "Do not lubricate the guide rails or the sliding elements!" Improper lubrication can worsen the problem or cause other issues.
• "Parts replacement does not solve this issue. Claims for replaced parts will be subject to review." This highlights that the problem is not a defective part but rather an accumulation of contaminants, and replacing components without proper cleaning will not resolve the Audi Q5 window noise.

Repair Procedure Summary

The repair procedure outlined in TSB 64 23 90 2064585/2 focuses on cleaning and, if necessary, further inspection and lubrication:

1. Begin by cleaning the affected window and its slot seals using lukewarm water and a gentle cleanser.
2. If the noise persists after cleaning and drying the seals, check the window for any visible marks that might indicate interference with the electric window regulator components.
3. If interference is suspected, remove the inner door trim panel and window slot seal to check for contact between the window, the window regulator, and the door wiring harness.
4. Verify that the window guide seal is correctly installed and adjust it if needed.
5. If noises are still present, examine the mechanical parts of the electric window regulator for issues.
6. Clean the sliding surfaces of the window regulator guide rails and the sliding elements. Use a microfiber cloth or brush with an all-purpose cleaner. Operate the window regulator up and down to ensure all sliding elements are cleaned.
7. Finally, lightly grease only the cable pulleys and cable drums of the window regulator, ideally using a brush for application.
