Check if your Audi has a Recall

 


Issue:

The rotor and the shaft of the integrated brake system may not have been welded to specifications. During a hard braking maneuver, the ABS hydraulic control unit rotor and shaft could separate, which could lead to a reduction in braking assistance (brake boost) as well as a loss of Antilock Brake System (ABS) functionality and Electronic Stability Control (ESC). Full mechanical braking is still available. During a hard braking maneuver, a reduction in brake assistance (brake boost) could lead to an extended stopping distance. In combination with a loss of ABS and ESC functionalities, this could increase the risk of a crash.

 

Precautions

A failure of the brake booster will be indicated by a warning message in the vehicle’s instrument cluster. Should this occur, customers are advised to contact their authorized AudieBay logo dealer without delay and make arrangements to have the vehicle serviced.
