Product Information

Alternator

If your car is running out of power (literally) it's likely due to a worn or failing alternator. Your vehicles car battery is responsible for storing enough energy to start the car while the alternator powers all the vehicles systems with the engine running while maintaining a battery charge. If your car dies while driving and the battery has little to no charge it's most likely due to a failed or failing alternator. Before condemning an alternator you can perform a simple test with a DVOM (digital volt meter). Also make sure the belt which drives the alternator is properly tensioned as well.

Alternator Failure Symptoms
  • Battery drains while car is running
  • Low voltage generated while car is running
  • Dim or flickering headlights
  • Dim or flickering interior lights
  • Electrical systems such as the radio, power windows, sunroof do not function

BSD Bus?
My car, 2011 N55 335i xdrive doesnt see this alternator and cannot control it. Claims the alternator is missing, bsd bus is fine. Is the internal regulator truly compatible. Very disappointed again. Alternator without bsd line is fixed at 50 amps and throws codes. Wont regulate properly.

Question Posted by Ryan
Does this regulator fully support the BSD LIN? My car could see the old alternator but not the new one. If not I cannot use
Answer (Posted by FCP Euro Products Team)
Do not know which unit you installed, or what software you are using, but yes this should register when installed. I have not seen one that would not.
