Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2026 Volkswagen Atlas?

• Check the gas cap: a loose or damaged cap is the most common, easy-to-fix cause and can trigger the light.
• Confirm fuel level and recent refueling — contaminated or incorrect fuel can create codes.
• Quickly inspect for obvious leaks, burning smells, or smoke; stop driving if you notice any of these.
• Look for dashboard indicators that accompany the light (e.g., battery, oil, temperature).
• If the light remains on after these checks, schedule a diagnostic with Nalley Volkswagen of Alpharetta for accurate code reading and repair.
