The check engine light reset might sound simple, but for a precision vehicle like the 2023 Mercedes-Benz AMG GT it’s critical to pair any reset with a correct diagnosis.

2023 Mercedes-Benz AMG GT Check Engine Light Codes

Common diagnostic trouble codes for a 2023 Mercedes-Benz AMG GT often involve oxygen sensors (P0130–P0167 range), ignition coil misfires (P0300–P0306), and emissions control alerts. Each code represents a different risk profile: an oxygen sensor fault can lower fuel economy and increase emissions, leading to higher long-term fuel costs and potential failed emissions tests; persistent misfires can damage the catalytic converter, turning a relatively modest repair into a much larger expense; and fuel system issues can create drivability problems and premature wear.
