H4M E-Tech (HR16 + 2 electric motors)
"Renault's 1.6 E-Tech hybrid: the naturally aspirated Nissan-designed 1.6 four-cylinder (H4M/HR16) with two electric motors and a clutchless multimode dog-clutch gearbox, in the Clio V, Captur II, Arkana, Megane, Symbioz, Dacia Jogger and Duster and Mitsubishi ASX, as full hybrid (140-145 hp) or plug-in (158-160 hp). The petrol engine itself has a good record. The weak point is the hybrid gearbox: a seal on the e-motor shaft can leak oil, and Renault has run campaigns on about 157,000 cars built 2019-2024, up to a new gearbox. Ask for proof that all campaigns were done."
K4J
"1.4-litre 16-valve petrol of the K family, found in the Clio II and III, Megane, Scenic and Modus. A durable, simple engine whose main risk is the timing belt: it is an interference engine, so a failed tensioner, idler or water pump that lets the belt slip bends the valves - change the full kit on time. Otherwise expect cheap electrical faults: ignition coils, the crankshaft sensor and a dirty throttle body."
