Excessive oil consumption on the 1.2 TCe (H5Ft)Engine

Engine / equipment: 1.2 TCe turbo petrol (H5Ft), 115–130 hp

Symptoms: Oil needs topping up often; the level can reach the minimum with no warning on the dashboard. In advanced cases, timing noise, loss of power or serious engine damage.
Possible cause described: Engines built between 2012 and mid-2015 burn too much oil. Renault applied a new calibration from June 2015 and reviews repair support case by case, depending on maintenance, age and mileage.
Check for the garage: Measure oil consumption with the dipstick over several thousand km, ask the dealer for a diagnosis and the calibration update, and keep every maintenance invoice to request support.
Cost cited in the source: Variable: from an ECU update to repairing or replacing the engine; Renault decides support case by case.A rough figure from the original database, not an up-to-date quote.

Stretched timing chain on the 0.9 and 1.2 TCeTiming system

Engine / equipment: 0.9 TCe (H4Bt) and 1.2 TCe (H5Ft) turbo petrol
Period mentioned: Approx. 2012–2020
Symptoms: Metallic chain rattle, especially when cold or at idle; engine light with a crankshaft–camshaft correlation code; in serious cases the chain jumps and damages the valves.
Possible cause described: The chain, meant to last the engine’s life, can stretch early; tensioners and plastic guides wear, and very long oil-change intervals speed up the wear.
Check for the garage: With any chain noise or a P0016 code, diagnose straight away: measure the stretch and check the tensioner and guides before the timing jumps. Shorten oil-change intervals.
Cost cited in the source: No verified estimate; ask the garage for a quote for the chain kit.A rough figure from the original database, not an up-to-date quote.
