2016 Alfa Romeo 4C Check Engine Light Flashing
A flashing check engine light on a 2016 Alfa Romeo 4C usually indicates an active misfire or severe combustion problem that can rapidly damage the catalytic converter and other engine components. When the light is flashing, stop driving if you notice rough running, loss of power, or unusual noises. Continued driving can overheat the exhaust and cause expensive downstream failures. Tow the vehicle to Herb Chambers Alfa Romeo of Boston or arrange dealer service immediately—our technicians will perform a fast, thorough scan and live diagnostics to locate ignition, fuel, or turbo-related faults. Acting quickly preserves performance, avoids costly secondary damage, and ensures any warranty-covered repairs are handled by certified personnel using OEM parts.
2016 Alfa Romeo 4C Check Engine Light Reset
Resetting the check engine light on a 2016 Alfa Romeo 4C can be done with an OBD-II scanner or, in some cases, by disconnecting the battery, but clearing codes without fixing the root cause only hides symptoms and risks greater long-term cost. At Herb Chambers Alfa Romeo of Boston we recommend a professional diagnosis and then a proper reset once repairs are completed. Our factory diagnostics verify the issue, confirm repairs, and ensure systems are re-learned correctly. Choosing dealership service delivers accurate fault isolation, OEM parts, and warranty protection—repairs covered under warranty must be performed at a certified dealership.

2016 Alfa Romeo 4C Check Engine Light Codes
Common codes on a 2016 Alfa Romeo 4C include P0300 (random/multiple misfires), P013x/P014x (oxygen sensor faults), P0420 (catalyst efficiency low), P0171 (lean condition), and P0299 (turbo underboost). Ignoring these codes can escalate costs: unresolved misfires can ruin a catalytic converter ($1,000+), turbo faults can lead to full turbo replacement ($1,500–$4,000 depending on labor and parts), and failed emissions components can prevent vehicle registration. Early diagnosis at Herb Chambers Alfa Romeo of Boston reduces long-term expense—our team identifies root causes, uses genuine parts, and applies factory procedures so repairs are reliable and, when applicable, covered by warranty when performed at a certified dealership.
