2019-2026 Audi Sliding Sunroof Noises TSB

Owners of 2019-2026 Audi vehicles may encounter undesirable Audi sliding sunroof noises and vibrations originating from the panorama sliding sunroof system. This issue is addressed by Technical Service Bulletin (TSB) 2078652/1, released on August 1, 2025, which provides guidance for technicians on how to diagnose and remedy these common complaints.

Symptoms

Owners typically notice various noises and vibrations emanating from the sliding sunroof assembly. These can include creaking, rattling, or grinding sounds, particularly when the sunroof is opened, closed, or as the vehicle travels over uneven surfaces. The primary complaint identified in the TSB is "noises from sliding sunroof."

Technical Background

The TSB explains that the sliding sunroof system, like many mechanical components, is subject to normal aging processes and environmental factors. Over time, the seals around the sunroof can dry out and lose their lubricating properties. Additionally, dust, dirt, and other debris can accumulate on the guide rail and other moving parts of the sunroof system, causing them to become gritty. These conditions lead to increased friction and wear, which manifest as the audible Audi sliding sunroof noises and vibrations reported by owners.

Repair Procedure Summary

Audi's recommended service procedure for addressing these noises focuses on proper cleaning and lubrication rather than immediate component replacement. Technicians are advised to clean and re-grease the sunroof seals and all friction surfaces within the sliding sunroof system. For seals, a specific grease, "Cryptostata G 052 111 A2," should be used. The TSB clarifies that cleaning and re-greasing have been shown to effectively remedy the noise issues. For more complex cases involving technical deviations, a separate, specific TSB with detailed instructions and illustrations will be available.

Required Parts

To perform the recommended lubrication, technicians will need the specified grease:

• Cryptostata G 052 111 A2 (for seals)

Additional grease types for friction surfaces should be identified using the ETKA parts catalog, specifically on the page dedicated to the sunroof system. The TSB also references PR numbers 3FE, 3FU, and 3FB, which correspond to different sunroof configurations.

Important Warnings

Owners should be aware of specific warranty limitations related to this issue:

• "Replacement sliding sunroof frames and mechanisms due to noise are not covered by the warranty."
• "This TSB is informational only and not applicable to any Audi Warranty."

This means that if the noise can be resolved by cleaning and re-greasing, the cost of this service may not be covered under standard Audi warranty terms, as it is considered a maintenance item rather than a defect requiring component replacement.

Owner Action

If your 2019-2026 Audi is experiencing Audi sliding sunroof noises or vibrations, it is recommended to schedule an appointment with an authorized Audi service center. Describe the symptoms clearly to the service advisor. The technician will likely perform the cleaning and re-greasing procedure outlined in TSB 2078652/1. Be prepared to discuss potential costs, as the TSB indicates that this service may not be covered under warranty.
