- Battery or charging warning light remains on
- Low or unstable charging voltage
- Battery repeatedly loses charge after testing good

- Noise from the alternator pulley or internal bearings
These symptoms can also be caused by the battery, drive belt, tensioner, wiring, grounds, fuses, or charging-control circuit. Test the complete charging system before replacing the alternator.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.
