Alternator for BMW - Genuine, OE, OEM & Aftermarket Parts

Your alternator is what charges your car's battery and provides all the electricity your car uses including the headlights and starter (the largest energy consumers). If your headlights are dim, or your car is difficult to start, you need to troubleshoot your charging system including the battery and alternator for possible replacement.

FAQ

How do I know if my BMW alternator is bad? Signs your BMW alternator may be failing include a dead battery, slow or malfunctioning accessories, dashboard warning lights, performance issues, trouble starting or frequent stalling, growling or whining noises, the smell of burning rubber or wires, and other electrical issues. If you notice any of these symptoms, it's important to check your alternator and charging system.

How long do BMW alternators last? Most BMW alternators last between 80,000 and 150,000 miles, or about seven years. However, this can vary based on driving habits, the condition of related components like the serpentine belt, and the alternator's quality. Regular vehicle maintenance is key to extending the life of your alternator.

Can you drive a BMW with a bad alternator? While it's possible to drive a BMW for a short distance with a failing alternator, doing so is not advisable. A malfunctioning alternator will not charge the battery, leading to a loss of electrical power and the potential for the vehicle to stop running. If you suspect your alternator is failing, it's best to address the issue promptly by replacing it with a new alternator.

What should I do if my BMW alternator needs replacement? If your BMW requires a new alternator, FCP Euro offers a wide range of high-quality alternators to fit your specific model. Choose from Genuine, OE, OEM, and Aftermarket options to match your vehicle's needs and budget. Additionally, consider replacing the serpentine belt and checking the battery and cables to ensure your BMW's charging system operates flawlessly.

By providing detailed information and a selection of high-quality BMW alternators, FCP Euro helps you make informed decisions about maintaining your vehicle's charging system, ensuring reliability and performance for years to come. FCP Euro has been providing OEM & Genuine replacement parts for European cars since it was established in 1986.
