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

• Start with simple items: a loose or damaged gas cap is often the cause and can be tightened or replaced quickly at our service center.
• If the cap isn’t the issue, we perform an OBD-II scan to read codes and identify the subsystem involved (engine, emissions, fuel, sensors).
• Our factory-trained technicians inspect the most common components first to limit costs and downtime — an approach that often costs less than repeated independent shop visits.
• For warranty-covered faults, remember repairs must be completed at a certified dealership to maintain coverage; we’ll guide you through the process and recommended next steps.

What is the most common reason for check engine light on a 2013 Mercedes-Benz S-Class S550?

• Emissions-related issues and sensor failures are frequent causes, including oxygen sensors, mass airflow sensors, and catalytic converter monitoring.
• For turbocharged engines like this S-Class, intercooler or boost-related sensor faults can also trigger the light.
• Our factory-trained technicians use OEM diagnostic tools to pinpoint the exact fault, which reduces repeat labor and long-term expense compared with iterative independent repairs.

How long does a check engine light service take?

• Initial diagnostic scans typically take 30–60 minutes, depending on vehicle condition and queue; our process provides a clear estimate before any work begins.
• Once codes are identified, repair time varies: simple fixes (gas cap, sensor replacement) may be same-day; complex repairs can require parts ordering and additional time.
• Choosing our dealership often yields faster, more reliable results and lower total cost over time due to correct-first-time repairs by factory-trained technicians.
• If a repair is warranty-covered, it must be performed here to preserve coverage — we’ll advise on expected timelines and coordinate parts and labor efficiently.
