BMW 530i Alternators
The alternator of your BMW 530i is responsible for producing the electrical energy that is consumed by the vehicle's various electric systems. It is driven by a serpentine belt and charges the battery while the car is running. Almost all internal combustion engines have this crucial component, and without a properly functioning alternator, the battery will run out of the "juice" or energy that is required to keep the car moving. Alternator problems are not unheard of, and when drivers notice that their headlights have suddenly dimmed, or the CHARGE sign has started to appear while they are driving, it would do them good to have their alternator checked. An original BMW 530i alternator is almost completely maintenance-free and is able last a good decade or so. You can find the original manufacturer sourced BMW alternators below.
