2017-2025 Audi Sunroof Glass Panel Breakage TSB 2078648/1

Audi has issued Technical Service Bulletin (TSB) 2078648/1, released on July 18, 2025, to provide service information regarding the billing procedures for a broken sunroof glass panel. This TSB applies to a wide range of Audi models from 2017 through 2025, including the Audi e-tron broken sunroof glass issue, and clarifies the conditions under which a replacement might be covered or charged back.

Symptoms

The primary symptom addressed by this TSB is straightforward: "The glass part of the sunroof is broken." This can manifest as a cracked or damaged panorama sliding sunroof glass panel or a sliding/tilting sunroof glass panel.

Technical Background

Sunroof glass panels are manufactured with a specific level of "inherent stress" that contributes to their strength. If this inherent stress is either too low or too high, the glass panel can become susceptible to breaking easily and quickly. While Audi regularly checks sunroof panels for quality and safety, a faulty glass panel installed in a vehicle can still break from a minor shock.

Common triggers for a broken sunroof glass panel include driving over a manhole cover or a curb. In some instances, even slamming a car door can generate enough force to cause the glass to break.

Important Warranty Information

This TSB provides critical guidance on the billing and warranty considerations for a broken sunroof glass panel. It is essential for owners to understand these conditions, especially concerning the 2017-2025 Audi models, including the Audi e-tron broken sunroof glass.

For vehicles still within their new model launch repair authorization period, workshops are instructed to create a case with the Technical Assistance Center (TAC) and reference TSB 2078648/1 in the first line of the TAC case.

Audi has defined specific criteria for determining if a broken glass panel may be considered a defect. If a sunroof glass panel breaks within 3 months of vehicle delivery or within the first 1,684 miles of operation, it is typically eligible for replacement and sent in for analysis. This implies that breakage within these parameters may be covered.

However, if a glass panel breaks after this initial period (i.e., beyond 3 months or 1,684 miles), it is generally considered to be due to an external impact, such as stone chipping. In such cases, any damaged parts submitted with mileage exceeding 1,684 miles or after 3 months of delivery will be charged back to the workshop or customer. This TSB is informational and does not directly apply to any Audi Warranty, but it outlines the conditions for billing related to sunroof glass damage.

Sunroof Option Codes

The TSB references specific PR numbers, which are Audi option codes related to different sunroof configurations. These codes help identify the type of sunroof installed in a vehicle:

• ?:or?:with 3FB
• ?:with 3FP
• ?:with 3FE
• ?:with 3FU

These codes are important for technicians to correctly identify the specific sunroof system when addressing a broken sunroof glass panel.

What Owners Should Know

If you experience a broken sunroof glass panel on your 2017-2025 Audi, particularly if it's a 2021 Audi e-tron broken sunroof glass, it's crucial to be aware of the warranty guidelines outlined in TSB 2078648/1. Contact your authorized Audi dealership to have the issue diagnosed. Be prepared to provide details about when the breakage occurred relative to your vehicle's delivery date and mileage. This information will help the dealership determine the appropriate billing and repair procedure according to Audi's guidelines.
