Frequently Asked Questions

What is the most common reason for check engine light on a 2024 Volkswagen Taos?

• Loose or faulty gas cap is the simplest and most common cause; it can trigger an emissions-related fault.
• Oxygen sensor or mass airflow sensor issues often follow; left unchecked they raise fuel consumption and emissions.
• Evaporative emission (EVAP) leaks, ignition misfires, and catalytic converter efficiency faults are other frequent causes.
• Ignoring these codes can lead to larger repairs; certified-dealership diagnostics identify the root cause and prevent repeat work.
• Repairs covered by warranty must be completed at a certified dealership to maintain coverage and long-term savings.

What does it mean when the check engine light comes on in a 2024 Volkswagen Taos?

• The light indicates the vehicle’s onboard diagnostics detected an emissions or engine-system fault via OBD-II.
• It may range from a minor issue to something that affects drivability or emissions compliance.
• A scan tool will retrieve one or more trouble codes that direct trained technicians to the source of the problem.
• Bringing your Taos to Nalley Volkswagen of Alpharetta ensures factory-trained techs use OEM tools and software for accurate results.
• Warranty repairs must be done at a certified dealership to protect coverage and deliver immediate and long-term savings.

What is the first thing to check when the check engine light comes on?

• Check the gas cap for tightness and visible damage; a loose cap often clears the code after a few drives.
• Note any changes in power, noise, or fuel economy—these details help our technicians diagnose faster.
• Look for accompanying lights (ABS, traction) and take a photo of the dash for reference when you arrive.
• If the vehicle runs poorly or the light is flashing, stop driving and have it evaluated to prevent catalytic converter damage.
