The wire coil profile used in the radiator tank seal may be deformed due to the very variable temperatures within the engine compartment.
Over time, and under unfavorable conditions, this could lead to the radiator seal coming loose. A loose radiator seal could come into contact with hot components in the engine compartment as a result of vibrations during driving. This could lead to the seal and, potentially, neighboring components starting to smolder, increasing the risk of fire.
The Audi A8 models affected by this recall were manufactured between June 2010 and July 2018.
