Frequently Asked Questions

What is the most common reason for check engine light on a 2024 Volkswagen Atlas Cross Sport?

• Loose or faulty gas cap causing EVAP system leak codes (easy to fix and often free of major repair).
• Sensors such as oxygen or mass airflow sensors—common wear items that affect fuel trim and emissions.
