2016 Mercedes-Benz AMG GT Check Engine Light Codes

At Mercedes-Benz of Lynnfield in Lynnfield, MA, we see a handful of recurring codes on the 2016 Mercedes-Benz AMG GT that represent the majority of diagnostic visits. Common trouble codes include oxygen sensor faults (P0130–P0167 family), misfire codes (P0300–P0312), turbocharger boost/sensor faults (P0234, P0299) and catalytic converter efficiency codes (P0420). Left unaddressed, oxygen sensor and catalytic issues elevate emissions and drop fuel efficiency, costing owners more at the pump; misfires can rapidly damage pistons, catalytic converters and cause erratic performance; turbo sensor faults can reduce boost and throttle response, risking expensive turbo repairs. At our Mercedes-Benz dealership we combine OEM diagnostic tools, genuine Mercedes parts, and factory-trained technicians to identify whether a sensor, wiring, or mechanical cause exists and to provide cost-effective repairs that protect resale value. We also highlight immediate and long-term savings: accurate diagnostics prevent unnecessary part swaps and extend component life, often making dealer service a smarter financial choice. To arrange an inspection, schedule service or check current service specials before your visit.

Check Engine Light Flashing

A flashing check engine light in a 2016 Mercedes-Benz AMG GT signals a potentially severe and active misfire or other urgent fault. When flashing, engine misfires can send unburned fuel into the exhaust stream, quickly overheating and destroying catalytic converters — an expensive outcome that escalates repair costs. Immediate dealership inspection limits damage: our technicians perform live-data captures, compression and ignition checks, and targeted repairs backed by Mercedes-Benz warranties when applicable. Mercedes-Benz of Lynnfield offers convenience features such as express service lanes, OEM parts availability, and transparent estimates so you can understand required repairs and costs up front. We proactively discuss ways to save — like timely repairs that prevent secondary failures — and we provide service financing to help you proceed without delay. Check our service specials for seasonal offers and loyalty discounts, and to protect your AMG GT, schedule service immediately when a light is flashing.

2016 Mercedes-Benz AMG GT Check Engine Light Reset

Resetting the check engine light on a 2016 Mercedes-Benz AMG GT is straightforward, but it’s only a temporary step unless the underlying fault is corrected. A reset clears stored codes but does not fix failed sensors, misfires, or emissions problems. At Mercedes-Benz of Lynnfield we recommend a full diagnostic before a reset so that the true cause is addressed and you avoid recurring failures or warranty complications. Our technicians use OEM procedures to verify repairs, perform resets, and then confirm that the system returns to normal under road and load conditions. Dealer service also ensures genuine parts and software calibrations that preserve performance and longevity. We prioritize transparency, offering clear estimates and discussing immediate and long-term savings from correct repairs. If you’re ready to resolve a persistent light or simply need a proper reset with verification, schedule appointment online and ask about our service specials to reduce cost.
