1.2 TCe Excessive Oil Consumption and Timing Chain Wear
SeriousEngineThe 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.
Pronounced metallic rattling or ticking noise from the timing cover during cold start and idle, Rapid drop in engine oil level between scheduled services, requiring regular litre top-ups, Check Engine or Stop Engine warning light with camshaft and crankshaft correlation trouble codes, Loss of engine performance, rough idling, or misfiring under moderate acceleration
- Withdraw the dipstick immediately upon arrival to verify the oil level is at the maximum mark and not pitch black
- Ask the vendor for documented oil top-up history and inspect garage invoices for timing chain or tensioner repairs
- Listen closely to the engine bay during a stone-cold start for any metallic chatter that lasts more than 2 seconds
