Frequently Asked Questions

What is the most common reason for check engine light on a 2011 Volkswagen Tiguan?

• Common causes include faulty oxygen sensors, catalytic converter issues, vacuum or EVAP leaks, and ignition misfires. These issues trigger diagnostic trouble codes that guide repairs.
• Many causes start small—an O2 sensor or loose gas cap—but can escalate into expensive repairs like a failed catalytic converter if ignored.
• At Nalley Volkswagen of Alpharetta, our factory-trained technicians identify root causes with OEM diagnostic tools to avoid unnecessary part changes and save you money immediately and over time.
• Remember: repairs covered under warranty must be performed at a certified dealership to preserve coverage and ensure correct repair procedures.

How long does a check engine light service take?

• Most initial diagnostics take 30–90 minutes depending on the complexity and whether additional road testing is required.

• It can range from minor issues—like a loose gas cap or sensor drift—to more serious engine, transmission, or emissions problems that affect performance and fuel economy.
• Our dealership uses Volkswagen-specific scanning tools to read codes, perform live data checks, and recommend repairs that address root causes rather than symptoms.
• For warranty-covered concerns, repairs must be completed at a certified dealership to maintain coverage and ensure OEM parts and procedures are used.
