2017 Renault Scenic 1.5L Diesel · WG17 FHV

The 1.2-litre TCe petrol (H5Ft) on 2016–2018 Scenic models is prone to severe oil consumption due to piston ring design and high manifold vacuum. Unchecked oil loss starves the hydraulic timing chain tensioner, causing chain stretch, metallic rattle on cold starts, and potential valve contact. Fuel dilution also accelerates bottom-end bearing wear. Renault issued ECU updates to alter manifold pressures, but oil-starved engines often need timing chain kit replacement (£900–£1,400) or full engine replacement exceeding £3,500.

The 7-inch landscape or 8.7-inch portrait R-Link 2 touchscreen controls navigation, radio, vehicle settings, and climate controls. On 2016–2019 cars, the system can suffer blackouts, freeze on the startup logo, or become unresponsive to touch inputs. In addition, Bluetooth drops connections and the reversing camera feed may fail. Early software branches were notoriously buggy; while dealer firmware updates cure software glitches, corrupted flash memory requires complete replacement of the central infotainment processor unit.
