BMW Alternators

Refine Results
Batteries help BMW cars and SAVs start; reliable factory BMW alternators keep them running. Whether your vehicle has a remanufactured alternator or a new alternator, there's no difference in how they work. They're both original BMW alternators, and they both reliably pass power among many electrical systems. However, even OEM alternators, for all their proven BMW quality, can fail with age, even before an alternator warning lights up your dash. Signs of alternator failure are wide-ranging. Your headlights may flicker. Your car entertainment system could malfunction. Your engine might squeak. Your battery could go dead. You could even smell burning under the hood near both the battery and alternator. Worse yet, you could involuntarily make an alternator go bad without symptoms. Incompatible accessory installs are one cause. A bad jump-start is another. If your BMW electrical systems fail, inspect it and test its charging system to be sure of the problem. Otherwise, it's a good idea to change an alternator every 80,000 to 150,000 miles. That's every 7 years or so. A genuine BMW alternator is the best replacement. It'll be compatible with your model right off the shelf. Check another maintenance project off your list -- order your alternator online today!
