2021 Audi e-tron and e-tron Sportback – Reason for the Fault
An error in the process at the sub-vendors production, the wafers for the FlexRay transceiver (a component within the electromechanical brake booster), parts that have not undergone all cleaning steps. Therefore part does not conform to the conditions and exacting specifications of the brand and may corrode during the vehicle’s service life-cycle. This may further lead to functional issues with the brake servo causing functional impairment of braking equipment. This includes brake assist, ABS, electronic stability control and the speed indicator in the instrument cluster.
However, full mechanical braking without brake boost is still available. But customers may experience a hard brake pedal and an increase in the brake pedal effort. This will lead to an extended braking distance. In combination with the loss of other braking functionalities such as ABS and ESC, the fault may lead to a crash. But, it is important to note that no crashes or injuries have been recorded pertaining to this recall. The driver will also get an indication on the vehicle’s instrument cluster and should contact the Audi dealer without delay, should this occur.
