OEM BMW Alternators

How Do I Know if My Alternator Is Refurbished?

Distinguishing a refurbished alternator from a new one can be tricky without a trained eye, but there are a few key signs to watch for. If you drive a BMW X3, keeping your alternator in good condition ensures your battery stays charged and all electrical systems run smoothly.

Expert Tips in Checking and Maintaining Your BMW Alternator

1. Inspect for Aftermarket Labels or Paint

Refurbished alternators often have non-OEM stickers or fresh paint to hide wear, which can be a clue it's not brand new.

2. Check Voltage Output with a Multimeter

A healthy alternator typically shows between 13.8 to 14.4 volts while running; anything lower could mean it's underperforming.

3. Listen for Unusual Whining or Grinding Noises

Noises during engine operation may indicate worn bearings, which are common in older or refurbished alternators.

4. Look at the Housing for Signs of Wear

Scratches, mismatched hardware, or worn mounting holes can reveal that the alternator has been previously used and reassembled.

5. Replace Your Starter for Complete Reliability

Pairing a dependable alternator with a new starter ensures smooth startups and full power delivery in your BMW X3.
