What is the white, crusty substance accumulating on my A6 Quattro’s battery post?

If you notice white, crusty stuff around the battery terminals of your A6 Quattro, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your A6 Quattro’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded A6 Quattro battery terminal?

Regularly inspecting and cleaning your battery terminals will help keep your A6 Quattro’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables.
