Frequently Asked Questions

How long does a check engine light service take?

• Initial diagnostic scan: typically 30–60 minutes using dealer-grade OBD-II tools to read codes and live data.
• Further testing or road checks: may add 1–3 hours depending on symptoms and whether intermittent faults appear.
• Repairs vary: simple fixes (sensor, hose) can be same-day; complex repairs (turbo, catalytic converter) may require parts and longer service time.
• We prioritize efficiency — same-day turnaround is common, and our factory-trained team often resolves issues faster and at lower total cost than independent shops.
• Schedule online to reserve a diagnostic slot and reduce wait times.

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

• Scan for stored codes immediately to identify the circuit or system at fault.
• Check fuel cap seating — a simple EVAP fault can trigger the light and is an easy fix.
• Inspect for obvious issues: wiring, vacuum hoses, visible fluid leaks, or misfire symptoms.
• If driving shows loss of power or a flashing light, stop driving and have the vehicle checked at the dealership to prevent damage.
• Remember: warranty-covered repairs must be completed at a certified dealership to preserve coverage.

What does it mean when the check engine light comes on in a 2016 Mercedes-Benz AMG GT?

• Any illuminated check engine light means the powertrain control module has detected a fault — codes narrow down the cause.
• Causes range from minor (EVAP leak, loose fuel cap) to critical (misfire, turbo underboost, catalytic damage).
• Even if the car seems to run fine, ignoring codes can accelerate component failure and increase future repair costs.
• Bring the vehicle to our certified team — we use manufacturer tools to diagnose and advise on immediate vs. scheduled repairs.
• Using the dealer for warranty repairs often results in lower long-term costs and keeps factory coverage intact.

How much does a check engine light diagnostic cost for a 2016 Mercedes-Benz AMG GT?

• Diagnostic fees vary by inspection depth; typical dealer diagnostics start competitively and may be lower than independent shops when you factor in accurate testing and the right parts.
• Simple code reads may be complimentary with service appointments; full diagnostics that include road testing and advanced lab time are priced accordingly.
• Immediate savings: accurate dealer diagnostics reduce unnecessary parts and repeat labor, lowering total cost of repair over time.
• Warranty-related repairs must be performed at a certified dealership to be covered.
• Contact our service team or schedule online for a clear estimate before work begins.

What is the most common reason for check engine light on a 2016 Mercedes-Benz AMG GT?

• Common triggers include misfires (ignition coil or spark plug), oxygen sensor faults, and EVAP leaks (loose cap or hose).
• Forced-induction engines can also show codes for turbo underboost or boost leaks, which should be addressed promptly.
• Left unchecked, these issues can harm the catalytic converter or engine and increase repair costs.
• Our factory-trained technicians diagnose quickly and recommend the most cost-effective repair path, often saving more than independent shops in the long run.
• We document repairs to preserve resale value and warranty history.
