Loose or damaged gas cap is the most frequent and simplest cause—an easy fix that often clears the light quickly.

Addressing these issues at Nalley Volkswagen of Alpharetta often costs less than independent shops while delivering factory-trained technicians and OEM parts. Repairs covered under warranty must be performed at a certified dealership to preserve coverage and ensure long-term savings.
