While parking brakes are no longer utilized as much as they once were, they are still a vital component. When parked on a hill, this brake keeps your vehicle locked into place and if your brakes decide to suddenly stop operating, this will bring you to an abrupt stop.
This motor ensures that your parking brake continues to operate and if it begins to fail, you will notice a lack of response when you engage the brake itself, or it might stick on. Chances are, you will receive a fault code on the dash to warn you of its failure. This is a common issue on most B6 Passats and is easily to replace.
