Frequently Asked Questions

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

• Look for obvious issues first: a loose or missing gas cap can trigger the light and is a quick fix.
• Check basic indicators — low oil, coolant temperature, and dashboard warnings — before driving long distances.
• If the light is steady, note recent driving conditions and performance changes to share with service staff.
• For the 2014 Volkswagen GTI, many issues start with sensor faults (MAF, O2) or ignition misfires; documenting symptoms speeds diagnosis.
• When warranty coverage or long-term reliability matters, have a certified dealership inspect the vehicle; warranty repairs must be completed at a certified dealer.
