The internal type of a Volkswagen Passat alternator regulator is located within the alternator and in some cases is replaceable. To replace the Volkswagen Passat regulator you must remove the power form the battery. The preferred way is to just remove the ground or negative battery cable prior to servicing the Volkswagen Passat alternator or regulator. If the regulator is internal and is not removable, then the entire Volkswagen Passat alternator assembly will need to be replaced.
