2022-2026 Audi Trim Peeling: TSB 2074058/2 Info

Audi has released Technical Service Bulletin (TSB) 2074058/2 to provide information regarding paint peeling on black trims and trim strips across various 2022-2026 Audi models. This bulletin clarifies the cause of the Audi black trim peeling issue and its implications for owners.

The affected vehicles include the 2022-2025 Audi A3, S3, and RS 3, the 2022-2025 Audi Q4 e-tron and Q4 Sportback e-tron, and the 2022-2026 Audi e-tron GT, RS e-tron GT, and S e-tron GT models.

Symptoms of Trim Damage

Owners may observe several types of damage on their vehicle's black trims and trim strips. Common complaints include the clear coat peeling from trim strips, a general appearance of coating flawed, or material detaching from the surface. The TSB also notes instances of corrosion or rust forming on door seals.

Other visual indicators of damage include paint color deviation on components like the rear lid spoiler, and paintwork bubbles on door trim molding strips. The bulletin includes photographic examples (Figure 1 and 2) showing the clear coat peeled off from the trim. Additional coating spots (Figure 3) and marks on neighboring rubber components (Figure 4 and 5) caused by applied liquids are also documented. Microscopic views (Figure 6) reveal spots of swelling on the affected surfaces.

Root Cause of the Peeling

Laboratory analyses conducted by Audi have concluded that the primary cause of the Audi black trim peeling is the use of overly aggressive cleaning solutions. These solutions, often combined with high-pressure cleaning, can irreversibly damage the vehicle's coating.

Specifically, industrial dirt removers, insect removers, and wheel cleaners are identified as culprits. The TSB explains that the application method, duration, and subsequent high-pressure cleaning contribute to the damage. Molecular analysis of the damaged surfaces revealed traces of phosphorus (P) and fluorine (F), elements not found in conventional anodizing or coating layers but commonly present in commercial cleaning products.

Important Owner Information

Audi has explicitly stated that this issue does not constitute a fault which is covered by warranty. This means that any damage resulting from the use of aggressive cleaning solutions will not be repaired under the vehicle's warranty.

Owners should be aware that no production solution is applicable, as the damage is attributed to external factors rather than a manufacturing defect. This information is crucial for owners experiencing Audi black trim peeling as it directly impacts potential repair costs.

Preventing Black Trim Damage

To prevent damage to black trims and trim strips, owners should exercise caution when cleaning their vehicles. It is recommended to avoid aggressive cleaning solutions such as industrial dirt removers, insect removers, and certain wheel cleaners. Always use car care products specifically designed for automotive finishes and follow the manufacturer's instructions carefully.

When washing, avoid using high-pressure cleaners directly on trim components, or maintain a safe distance and pressure to prevent coating damage. Regular, gentle cleaning with appropriate products can help maintain the appearance and integrity of your Audi's black trim.
