- 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

- 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.
