2022-2026 Audi Sunroof Noises TSB 2078652/1

Experiencing annoying noises or vibrations from your sliding sunroof in your 2022-2026 Audi? You're not alone. Audi has issued Technical Service Bulletin (TSB) 2078652/1 to address customer complaints regarding "sliding sunroof noises" and "sunroof vibrations" in various models. This TSB provides guidance to technicians on diagnosing and resolving these issues, emphasizing maintenance over costly replacements.

Symptoms

Owners typically report the following issues related to their sliding sunroof:

• Noises from sliding sunroof: This can include creaking, rattling, or squeaking sounds.
• Vibrations: A noticeable shaking or trembling sensation associated with the sunroof.

These symptoms are often linked to the "roof systems, special equipment -> panorama sliding sunroof" or "sliding/tilting sunroof" components. If you hear an Audi e-tron sunroof noise, it's likely due to the conditions described in this TSB.

Diagnosis and Trigger Conditions

According to Audi, sliding sunroof systems are subject to normal wear and tear. Over time, the seals can dry out and become dusty. Additionally, the guide rails and other moving parts of the sunroof mechanism can accumulate dirt and debris. These conditions are the primary cause of the "sliding sunroof noises" and vibrations reported by owners.

Repair Procedure Summary

The TSB highlights that while some dealers have opted to replace entire sliding sunroof frames due to noise complaints, analyses show that cleaning and re-greasing the existing components would often resolve the issue. The recommended service procedure involves:

1. Lubricating dry seals: Any dry seals within the sunroof system should be lubricated using a specified grease.
2. Re-greasing friction surfaces: All friction surfaces must be re-greased with the appropriate type of lubricant. Specific grease types for these surfaces can be found in the Electronic Technical Information System (ETKA).
3. Addressing technical deviations: For any technical deviations that might contribute to noise, a specific TSB with detailed instructions, including diagrams, will provide guidance on where and how to re-grease.

It's important to note that the replacement of sliding sunroof frames and mechanisms due to noise, when caused by these preventable conditions, is typically not covered under warranty.

Required Tools or Parts

To properly address the sliding sunroof noises, technicians will need specific lubricants:

• Cryptopaste G 052 141 A2: This specific grease should be used for lubricating the seals.
• Other specified greases: For friction surfaces, the required grease types are detailed within the ETKA system. Your Audi service center will have access to this information.

Owner Action

If you are experiencing Audi e-tron sunroof noise or similar issues with your 2022-2026 Audi's sliding sunroof, it is recommended to:

• Schedule an appointment with an authorized Audi service center.
• Describe the specific noises or vibrations you are hearing.
• Mention Technical Service Bulletin (TSB) 2078652/1, as it directly addresses these symptoms.
• Understand that this type of maintenance (cleaning and re-greasing) is generally not covered under Audi's warranty, as it's considered a normal wear and tear item. The TSB itself is informational and not applicable for warranty claims.
