Surface Cracks In Cooling Duct Crosspieces
WARNING: This page is about a different car, the 2022 Audi SQ7, 2022 Audi S7, and 2022 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.
The cracks -arrow- on the surface of the cooling channels were produced during the manufacturing process.
NOTE:
The surface cracks in the cooling duct crosspieces do not mean the ceramic brake rotor is faulty.
