2023-2026 Audi Ceramic Brake Disc Cracks TSB

Audi has released Technical Service Bulletin (TSB) 2077435/1 to address customer inquiries regarding the appearance of cracks on the friction ring surface of ceramic brake discs. This bulletin clarifies that these cracks are an expected characteristic of the new generation ceramic brake discs found in various 2023-2026 Audi models, including the 2023 Audi e-tron.

Symptoms

Owners of affected Audi vehicles may observe what appears to be "Significant cracks on surface of the friction ring" on their ceramic brake discs. These visual characteristics are the primary concern addressed by this bulletin.

Technical Background

According to Audi, the new generation of ceramic brake discs (CCB+) exhibits more significant cracks on the surface of the friction ring. These cracks are a result of the production process itself. During manufacturing, as the material cools, the friction ring surface contracts more rapidly or differently than the base material. This differential contraction leads to the formation of these visible cracks.

Important Information for Owners

This TSB provides crucial information for owners concerned about the appearance of their ceramic brake discs. Audi explicitly states that "No measures required" are necessary for these cracks. The functionality of the brake system is not impacted by this condition, meaning your vehicle's braking performance and safety remain unaffected. Therefore, there is "no reason to replace parts" simply due to the presence of these cracks.

It is important to understand that this TSB (2077435/1) is for informational purposes only and is not applicable to any Audi Warranty claims related to these cracks. If you notice what you believe to be 2023 Audi e-tron ceramic brake disc cracks, rest assured that, according to Audi, this is a normal characteristic.
