2025 Mercedes-Benz AMG GT Check Engine Light Reset

Resetting the check engine light on a 2025 Mercedes-Benz AMG GT may seem simple, but a reset without correcting the underlying issue only hides a symptom and risks long-term damage. Our technicians at Mercedes-Benz of Tampa begin with an OEM-level scan to retrieve and interpret fault codes, assess freeze-frame data, and verify live sensor readings. If a software update or module recalibration is needed, we apply Mercedes-Benz-approved procedures so the fix is durable. Choosing our dealership over an independent shop means you receive full transparency on diagnostics, OEM parts when replacement is necessary, and factory-trained technicians familiar with AMG-specific calibrations and turbocharger systems. We document all work, explain the repair options, and outline warranty coverage—repairs covered by warranty must be performed at a certified dealer to remain valid. You’ll also find cost-saving opportunities through our service specials, and flexible payment via service financing. To protect performance and avoid repeat visits, schedule service with Mercedes-Benz of Tampa—our team delivers a transparent, factory-backed reset and repair process that keeps your AMG GT operating at peak performance.

2025 Mercedes-Benz AMG GT Check Engine Light Codes

In Tampa, drivers of the 2025 Mercedes-Benz AMG GT commonly encounter a few recurring diagnostic trouble codes: misfire codes (P0300–P0304) from ignition coil or spark plug issues, P0171/P0174 indicating a lean condition due to vacuum leaks or fuel delivery problems, and P0420 showing catalytic converter efficiency concerns often tied to faulty oxygen sensors or exhaust leaks. Turbo-related sensors and boost control faults also appear on high-performance models. Ignoring these codes can escalate costs: a misfire left untreated can damage pistons or the catalytic converter, turning a modest ignition repair into a major engine rebuild; a failing oxygen sensor or exhaust leak reduces fuel efficiency and can lead to premature catalytic converter failure, which is significantly more expensive. At Mercedes-Benz of Tampa, we identify codes precisely, estimate repair costs with full transparency, and highlight immediate and long-term savings from addressing issues early. Our technicians perform diagnostic checks, road tests, and system-level inspections using OEM tools so repairs are accurate and lasting. Take advantage of our documented inspections, certified repairs, and available service specials. To protect your vehicle and avoid further expense, schedule service today.

Check Engine Light Flashing

A flashing check engine light on a 2025 Mercedes-Benz AMG GT signals a severe condition—typically an active misfire that can allow raw fuel into the exhaust and damage the catalytic converter, or an ignition/engine fault that threatens immediate harm.

Our service team treats flashing lights as a high priority: we perform expedited OEM diagnostics, inspect ignition coils, spark plugs, fuel delivery, and turbo systems, and take necessary steps to minimize further damage. We frequently run targeted inspections and offer corrective repairs with OEM parts and Mercedes-trained technicians to restore performance reliably. Mercedes-Benz of Tampa also provides service financing to get critical repairs done immediately, and we advertise rotating service specials to make repairs more affordable.
