What is the white, crusty stuff around my Passat’s battery post?

The white, crusty stuff that can accumulate around Passat car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

Regularly inspecting and cleaning your battery terminals will help keep your Passat’s electrical system running smoothly.
