2023-2025 Audi Models: Sunroof Glass Panel Broken TSB

Owners of various 2023-2025 Audi models, including the 2023 Audi e-tron, may experience an issue with a broken sunroof glass panel. Audi has released Technical Service Bulletin (TSB) 2078648/1 to address billing procedures for dealers when replacing cracked or damaged sunroof glass panels.

Symptoms

The primary symptom of this issue is a cracked or broken sunroof glass panel. This can affect either the panorama sliding sunroof or the standard sliding/tilting sunroof. Owners may notice visible cracks or shattered glass.

Technical Background and Causes

Audi's TSB 2078648/1 explains that sunroof glass panels are manufactured with a specific 'inherent stress' level. This stress is crucial for the glass's strength and durability. If a glass panel has insufficient inherent stress, or if the stress is too high, it can become prone to breaking easily and quickly.

Even minor impacts, such as driving over a manhole cover, hitting a curb, or simply slamming a car door, can cause a faulty glass panel to crack or shatter. The TSB notes that these panels are regularly checked for quality, but a faulty panel can still break from the first shock.

Dealer Service and Warranty Information

This Technical Service Bulletin is primarily informational, guiding dealerships on the billing process for replacing a broken sunroof glass panel. It applies to vehicles still within their new model launch repair authorization period. For these vehicles, workshops must create a case with the Technical Assistance Center (TAC), referencing TSB 2078648/1.

If a glass panel breaks within 3 months of vehicle delivery or within the first 1,684 miles, it is considered a potential defect. In such cases, the panel should be replaced and sent in for analysis. However, if the breakage occurs after this period or mileage, it is generally attributed to an external impact (e.g., stone chipping) and may be charged back to the customer.

It is important to note that this TSB itself is not applicable to any Audi Warranty. Dealers are advised to check with their Parts Department and ETKA for the latest information and to consult the Repair Manual for fastener replacement guidelines.

Owner Action

If you notice a broken sunroof glass panel on your Audi, especially if it's a 2023 Audi e-tron or another affected model, it is recommended to contact your authorized Audi dealership. Provide them with details of when the breakage occurred, particularly if it was within the initial 3 months or 1,684 miles of vehicle delivery, as this may qualify for a specific repair authorization process. The dealer will assess the damage and determine the appropriate billing procedure based on the TSB guidelines.
