Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2019 Mercedes-Benz AMG GT?

• Check for a loose or faulty gas cap—it's a common, simple cause that can trigger the light and is quick to resolve.
• Confirm the fuel you used is premium unleaded, as recommended; incorrect fuel can lead to drivability codes and performance loss.
• Look for obvious signs: unusual noises, loss of power, smoke, or strong odors—these require immediate attention at our dealership.
• If the vehicle is under warranty, any covered repairs must be completed at a certified dealership to preserve coverage and long-term savings.
• When in doubt, schedule a factory diagnostic with our trained technicians via Schedule Service.

How long does a check engine light service take?

• Basic diagnostics usually take 30–90 minutes to read codes and identify straightforward issues like sensor faults or a loose fuel cap.
• Complex repairs—such as turbo, fuel, or emissions system work—can take several hours to a full day depending on parts and required labor.
• We provide clear time estimates before work begins; factory-trained technicians and OEM tools streamline diagnosis and repair for faster, accurate results.
• Choosing our dealership often results in immediate and long-term savings: fewer repeat visits, genuine parts, and warranty protection that independents can’t offer.
