HR12DDT / HR12DDV (Renault H5F 6xx)
"The new three-cylinder 1.2 turbo petrol of the Renault Austral, Espace, Rafale, Clio VI and Captur and the Dacia Duster III (2022 on): 48V mild hybrid (130 hp), LPG Eco-G, and the E-Tech full hybrid and plug-in hybrid (200-300 hp system power). Not related to the old four-cylinder 1.2 TCe. The full-hybrid Austral and Espace built 2022-2024 have had a string of campaigns: a crankcase breather hose that lets fuel dilute the oil (risk of engine seizure), spark plugs replaced for misfires, and cooling-system parts. Mild-hybrid versions have no known engine faults so far. Check that every Renault campaign has been done."
E7J
"Simple 1.4-litre 8-valve petrol of the Clio I and II, Megane I, Scenic I, Kangoo and the Dacia SupeRNova/Solenza. Owners report 225,000-310,000 km on original engines. Its weak points are cheap: a cracking distributor cap, plugs and leads, and temperature sensors that upset starting and idle. It has a timing belt to change on schedule and no hydraulic lifters, so the valve clearances need periodic adjustment."
