The third-generation Renault Mégane was produced from 2008 through 2016, undergoing two facelifts during its nine-year production run. The most common body styles are the estate (station wagon) and 5-door hatchback, though coupe and sedan variants (sold under the Renault Fluence nameplate) were also produced.
This guide details the locations, relay and fuse assignments, and circuit diagrams for the Renault Mégane 3 (chassis codes B95, D95, K95, E95; C platform).
