Affordable BMW Alternator Replacements | Genuine, OE & OEM BMW Alternators

Many BMW mechanics will agree that the alternator is one of the more complex auto parts in your BMW engine. The BMW alternator is a source of electricity for the other electrical BMW parts in your engine bay. The internal spinning magnets in your BMW alternator create an electrical current that is then converted into a direct current to charge and recharge components like your BMW's battery. Bosch alternators are offered in the aftermarket as Remanufactured units. Bosch REMAN is considered OEM on many BMW, Mercedes, and Volkswagen applications. Make sure when you place your order for your BMW alternator to keep an eye out for your "core tag." This will allow you to get a core credit when you send the core on your worn-out BMW alternator back to us. These core credits are usually processed within 5 business days and will credit back to your original payment source. If you use Affirm and decide to finance your BMW parts purchase, the balance owed on your Affirm transaction will be reduced by the amount of your core credit.
