Audi Alternator - Bosch AL0891N

Brand new 140 amp Bosch alternator

The alternator is your Audi's primary power source. The battery provides the power to start the car while the alternator provides the power to the vehicle as its running. More time than not, a failing alternator will not provide the power required by the vehicle and instead the battery will get drained as a back up source.

When the engine is running the alternator should provide a constant 13V-14V power supply. If your Audi is running below that it could be due to a faulty voltage regulator (usually part of the alternator and not exchangeable retrospectively) or a bad ground. If the alternator is the cause of the electrical system faults it will need to be replaced.
