Everything You Need to Know About Alternators

What They are

They are important parts of the charging systems in Volkswagen models. Without a working alternator, your car, wagon, or SUV wouldn't run at all.

What They Do

They transform mechanical energy into electrical energy. They help charge the car battery and power the lights on the dashboard. They also power your windows and locks, the steering system, windshield wipers, and even infotainment systems.

How One Works

The process starts with the engine. It moves serpentine and drive belts, turns a pulley, spins a rotor shaft, and rotates magnetic coils. This movement generates a magnetic field, whose energy a rectifier on the alternator captures as alternating current (AC) power and turns into direct current (DC) power.

Why They Fail

Their parts are broken, their belts have become too tight, the wrong accessories have been installed, or a bad jump-start.

The Signs One's Failing

• Warning lights on the dash
• Problems with lighting
• Electronics behaving erratically
• Engine squeaking
• A dead car battery
• A burning smell around the battery or alternator
• Alternator fluid leaks

Noticing any of these issues? You will want to run an alternator inspection ASAP, along with a charging system test.

When to Replace One

Every 80,000 - 150,000 miles or once every 7 years, whichever comes first. Be sure to check your owner's manual's maintenance schedule for additional information. If it's time to order a new one, make sure it's genuine.

Why Buy a Genuine Volkswagen Alternator

Volkswagen will have it manufactured to fit the model you drive. That's a guarantee the aftermarket can't provide.
