1.2 TCe chain, EDC gearbox and campaigns on the Mégane IVKnown weak points
- Engine / equipment
- Renault Mégane IV (petrol, diesel and E-Tech)
- Period mentioned
- 2016–2023
- Symptoms
- Chain noise on start-up on the 1.2 TCe (H5F); an EDC gearbox that overheats or jerks when pulling away (especially GT TCe 205); drop links; at the roadworthiness test, suspension and lights.
- Possible cause described
- The guide rates the 1.3 TCe as reliable. Recalls: GT clutch (1/11/2015–23/1/2017), particles in the oil-pressure valve of the R.S. M5P (1/12/2017–6/5/2019), R9N fuel line (8/11/2018–20/6/2019), curtain airbags and child lock (2016).
- Check for the garage
- Check the campaigns by VIN; change the EDC oil every 50,000–60,000 km; listen to the 1.2 TCe chain.

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.

- Period mentioned

- Symptoms
- “Stop” warning with the message “electrical fault, danger”, loss of drive and the car stranded.
- Possible cause described
- The “Onduflex” washer linking the main electric motor to the dog-clutch gearbox (which has no clutch) can break. Renault preventively reprogrammed over 150,000 cars in France built between 29/4/2020 and 13/4/2023.
- Check for the garage
- Ask Renault by VIN whether the reprogramming was done; with the warning, stop somewhere safe.
- Cost cited in the source
- Free reprogramming.A rough figure from the original database, not an up-to-date quote.

- 1.5 dCi (K9K) with particulate filter
- Period mentioned
- 2010 onwards
- Symptoms
- Particulate-filter or emissions warning, limp mode with loss of power and frequent regenerations.
- Possible cause described
- The filter clogs, especially on cars that mostly make short town trips and never complete a regeneration.
- Check for the garage
- Read the soot load with a diagnostic tool, run a forced regeneration at the garage and check the differential-pressure sensors and EGR. Make long road trips now and then.
- Cost cited in the source
- No verified estimate; from a regeneration to replacing the filter.A rough figure from the original database, not an up-to-date quote.
