Alternators

Refine Results

Your vehicle's alternator is something that helps to convert mechanical energy to electrical energy that is necessary for a variety of systems in your BMW to operate properly. While your vehicle does have a battery, this doesn't generate enough power for everything within your vehicle to work properly. The battery would die if you didn't have an alternator in place to help keep it charged and to send recycled power to other areas. If your alternator starts wearing out, you want to make sure that you don't ignore the signs and get an OEM replacement right away, otherwise, your vehicle will begin to struggle to create power. You'll notice your lights dimming, your power steering failing, and eventually, your entire will BMW will stop running if you fail to get your alternator replaced when you need to.
