Renault Clio Common Faults in the UK
Mk4 2012–2019, Mk5 2019+ — supermini hatchback. Updated 2026-05-11.
The Renault Clio is one of Ireland's most popular superminis. The Mk4 (2012–2019) is reliable but has a known timing belt replacement requirement on 1.5 dCi diesel engines and documented EGR valve fouling. The Mk5 (2019+) with the 1.0 TCe turbopetrol and optional mild hybrid is significantly more modern and reliable overall. Key concerns: EDC dual-clutch gearbox reliability on Mk4, clutch wear on manual diesels, and infotainment updates needed on early Mk5. Best buy: 2021+ Mk5 1.0 TCe manual. Worst: Mk4 with high-mileage diesel and EDC auto.

Best and worst years to buy
2021+ Mk5 benefits from resolved early-build software issues, a more mature 1.0 TCe engine, and optional E-Tech hybrid. These represent the most reliable Clios on the Irish used market.
Early Mk4 (2013–2015) Irish examples suffer from EDC dual-clutch gearbox judder, EGR fouling on diesel, and 1.5 dCi timing belt neglect. These are the most problematic Clios to buy used.
Known faults — Renault Clio Mk4 2012–2019, Mk5 2019+
Documented from HonestJohn, owner forum sentiment (PistonHeads, Reddit), DVSA recall portal, and Autoza dealer-feedback aggregation. Severity is colour-coded.
Timing belt — 1.5 dCi diesel (Mk4)
Critical — engine-out potential- Symptoms
- No warning — belt fails without symptoms; catastrophic engine damage results
- Years affected
- Mk4 2012–2019 (1.5 dCi diesel) — Replace every 60,000 km or 5 years
- Indicative repair (UK)
- £400–£650 preventative kit; £2,000–£4,000 engine if belt snaps
- What to check before buying
- Verify belt change in service history. The Renault 1.5 dCi is an interference engine. No record means budget for immediate replacement before buying.
EDC dual-clutch gearbox judder (Mk4)
Major — significant repair cost- Symptoms
- Shudder from standstill; hesitant 1st-to-2nd change; jerky slow-speed behaviour
- Years affected
- Mk4 2012–2019 (EDC automatic) — Often from 40,000 km on; worsens with age
- Indicative repair (UK)
- £300–£800 re-learn and fluid change; £1,500–£2,800 mechatronic or replacement
- What to check before buying
- Test at walking pace in traffic and from cold. The Mk4 EDC is the weakest part of the car. If buying automatic Mk4, only accept a price that reflects the gearbox risk. Mk4 manual is far more reliable.
EGR valve fouling (1.5 dCi diesel)
Moderate — service-level fix- Symptoms
- Engine Management Light; rough idle; black smoke under acceleration; loss of power
- Years affected
- Mk4 2012–2019 (diesel) — Above 80,000 km or heavy short-journey use
- Indicative repair (UK)
- £350–£700 EGR clean or replacement
- What to check before buying
- Check EML during test drive. Diesels with service history showing mostly city driving are highest risk. An Italian tune (hard motorway run) before the test can mask symptoms temporarily.
Infotainment software (Mk5 early build)
Minor — wear-and-tear- Symptoms
- MediaNav or Easy Link screen freezes; CarPlay drops out; slow wake from standby
- Years affected
- 2019–2021 Mk5
- Indicative repair (UK)
- £0 — dealer software update resolves most cases
- What to check before buying
- Test CarPlay and navigation responsiveness during test drive. Renault dealer OTA update is free. If freezing occurs, request update as a condition of sale.
Clutch wear (manual diesel Mk4)
Moderate — service-level fix- Symptoms
- Clutch slip under load; high biting point; difficulty engaging reverse
- Years affected
- Mk4 2012–2019 (manual diesel, urban-use cars) — Above 80,000 km in city-use cars
- Indicative repair (UK)
- £600–£950 clutch kit replacement
- What to check before buying
- Test on a moderate hill start — clutch slip (engine revs but car moves slowly) indicates wear. Check the biting point height — high biting point means the clutch is near end of life.
Handbrake cable stretch (Mk4)
Minor — wear-and-tear- Symptoms
- Handbrake requires excessive pulls to hold on a slope; rear drums not holding on hills
- Years affected
- Mk4 2012–2019, especially drum-brake variants
- Indicative repair (UK)
- £150–£280 cable and adjustment
- What to check before buying
- Test the handbrake on any slope. More than 8 clicks to hold firmly indicates cable stretch. Drum brakes on the rear are a common NCT failure point — inspect before buying.
Who this car suits — and who should look elsewhere
First-time buyers and young drivers seeking low running costs. City and suburban driving. Buyers who want proven reliability on a small budget. Mk5 E-Tech hybrid for fuel economy.
Buyers who need an automatic gearbox and want reliability — avoid the Mk4 EDC. Rural drivers who need more ground clearance. High-mileage diesel buyers doing short journeys.
