          Frequently Asked Questions

          What does the Bosch AL25M Alternator do?

          The alternator is a critical component of your vehicle's electrical system. It converts mechanical energy from the engine into electrical energy, charging the battery and powering the vehicle's electrical systems while the engine is running. A functioning alternator is essential for maintaining a reliable power supply to your vehicle's electrical components.

          How do I know if my Alternator needs replacement?

          Key symptoms of a failing alternator include dim or flickering headlights, battery warning light illuminated on the dashboard, difficulty starting the vehicle, electrical accessories malfunctioning, and a noticeable decrease in engine performance. If you experience any of these issues, it may be time to replace your alternator.

          Can I install the Bosch AL25M myself?

          Yes, the Bosch AL25M can be installed by a DIY enthusiast with basic automotive knowledge. Proper precautions should be taken to ensure safety and to follow the manufacturer's installation guidelines.

          What are the symptoms of a faulty Alternator?

          Common symptoms of a failing alternator include dimming headlights, electrical failures, battery warning lights, and engine performance issues. If you see DTCs such as P0562 (System Voltage Low) or P0620 (Generator Control Circuit Malfunction), it may indicate a failing alternator.
