2022-2026 Audi Black Trim Paint Peeling TSB 2074058/3

Audi has released Technical Service Bulletin (TSB) 2074058/3 to address customer and workshop findings of paint peeling and coating flaws on black exterior trims and trim strips across several 2022-2026 models. This bulletin provides crucial information regarding the cause of this cosmetic issue, which is often observed as Audi black trim peeling.

Revision History

This Technical Service Bulletin has undergone several revisions to include updated information and additional models:

• Revision 3 (Current): Revised header to include new models.
• Revision 2 (March 4, 2025): Revised the title, header, condition, technical background, service, warranty, and additional information sections.
• Revision 1 (May 28, 2024): Initial publication of the bulletin.

Symptoms of Black Trim Damage

Owners may notice various forms of damage on their vehicle's black exterior trims. The primary symptom reported is that the "clear coat has peeled off from trim strips." Other observed issues include:

• Paint color deviation on components like the rear lid spoiler.
• Material detaching from window channel seals.
• Damaged components related to power window regulators and side windows.
• Paintwork bubbles on door trim molding strips.
• Corrosion or rust on door seals.
• Flawed coating on door window trim molding and roof trim molding.
• Spots of additional coating and a fine spray pattern, often caused by cleaning agents.
• Marks forming on neighboring rubber components due to applied liquids.
• Swelling of the coating, visible under magnification.

These symptoms can affect various body attachments and installations, including wheel housings, outer door panels, and door body seals, leading to the noticeable Audi black trim peeling.

Root Cause of the Damage

Laboratory analyses conducted by Audi have concluded that the primary cause of this trim damage is the use of aggressive cleaning solutions. These solutions, especially when applied with pressure from a high-pressure cleaner, can cause irreversible damage to the trim's coating.

Specific types of cleaning solutions identified as problematic include:

• Industrial dirt removers
• Insect removers
• Various commercially available wheel cleaners

Analysis of damaged surfaces revealed traces of phosphorus (P) and fluorine (F). These elements are not naturally present in the conventional anodizing and additional coating layers used by Audi, confirming that external cleaning agents are responsible for the damage. The duration and method of application of these cleaning solutions significantly impact the severity of the damage, leading to the Audi black trim peeling observed.

Important Warnings for Owners

Audi Technical Service Bulletin 2074058/3 explicitly states that this issue does not constitute a fault covered by warranty. This means that any repairs or replacements needed due to paint peeling or coating damage on black exterior trims, caused by aggressive cleaning solutions, will likely be at the owner's expense.

Owner Action

If you are experiencing Audi black trim peeling or other related damage, it is recommended to:

1. Avoid aggressive cleaning solutions: Refrain from using harsh chemicals, industrial dirt removers, insect removers, or certain wheel cleaners on your vehicle's black exterior trims.
2. Use appropriate cleaning methods: When cleaning your vehicle, use mild, pH-neutral car wash soaps and soft cloths or sponges. Avoid high-pressure washing directly on the trim components.
3. Consult your dealer: If your vehicle's black trims are already damaged, contact an authorized Audi service center. While the issue is not covered under warranty, they can provide options for replacement parts.

This TSB serves as an informational guide for technicians and owners, highlighting the importance of proper vehicle care to prevent such cosmetic damage.
