Renault Clio 1.5 dCi reliability and the Captur dCi
Renault Clio 1.5 dCi reliability and Captur 1.5 dCi faults: injectors, bearings, EGR and DPF, with checks for small-car stock.
· 7 min read
Renault Clio 1.5 dCi reliability is good on the Clio IV (2012–2019) and Clio V (2019 onwards), and the Captur dCi shares the same engine and verdict. The K9K diesel is frugal and long-lived when serviced, with injectors, EGR, DPF and the timing belt as the main items. Older Clio II and III dCi engines carry bearing risk. Diesel superminis now sell mainly in specific markets, so buy them with a clear exit in mind.
Clio and Captur generations with the 1.5 dCi
The 1.5 dCi has powered every Clio since 2001 and both Captur generations. The generation tells you more about risk than the engine name.
| Model | Years | 1.5 dCi outputs | Notes |
|---|---|---|---|
| Clio II | 2001–2005 (diesel in this period) | 65–100 PS | Early K9K, bearing risk |
| Clio III | 2005–2012 | 70–105 PS | Early cars still in the bearing-risk period |
| Clio IV | 2012–2019 | 75, 90, 110 PS | Mature K9K; most common used dCi Clio |
| Clio V | 2019 to about 2022 for diesel | Blue dCi 85, 100 | AdBlue; diesel dropped as hybrids arrived |
| Captur I | 2013–2019 | 90, 110 PS | Same platform and engine as Clio IV |
| Captur II | 2019 to about 2022 for diesel | Blue dCi 95, 115 | AdBlue |
Is the Clio 1.5 dCi a reliable engine?
Yes. In the Clio IV and V, the 1.5 dCi is a reliable engine that commonly exceeds 200,000 km with correct servicing. It is cheap to run, light on fuel and simple to repair, which is why so many Clios were sold to fleets, driving schools and high-mileage private drivers.
The known weak points of the K9K in a Clio:
- Injectors, especially at high mileage or after poor-quality fuel;
- EGR valve, sticking on cars used in town;
- DPF, clogging on cars that rarely see the motorway or used the wrong oil;
- Turbo, usually failing only after oil neglect;
- Timing belt and water pump, due at the scheduled interval;
- Clutch and dual-mass flywheel at high mileage.
On Clio II and III cars built between about 2003 and 2006, crankshaft bearing failures were a known problem. Those cars are now cheap end-of-life stock and should be priced as such. For the full engine background, see our guide to Renault 1.5 dCi engine reliability.

Request accessWhat faults does the Captur 1.5 dCi have?
The Captur 1.5 dCi has the same engine faults as the Clio, plus a few that come from its role as a family crossover. It is heavier, more often used for short trips and more often has the EDC automatic.
- EDC dual-clutch automatic: judder when pulling away, jerky shifts in traffic and gearbox warnings; test from cold.
- DPF and EGR issues from short-trip family use.
- Blue dCi engines (Captur II): AdBlue system faults, and on Renault engines built between September 2018 and October 2021 an oil consumption issue that, according to L'argus, Renault fixes with an engine software update on request.
- Interior wear: removable seat covers and soft trim on Captur I show wear quickly.
- Infotainment: R-Link freezes and slow screens.
What should I check on a high-mileage Clio dCi?
On a high-mileage Clio dCi, focus on the timing belt, the emissions system and the clutch, which together decide whether the car is profitable. Use this sequence:
- Service history: oil changes at the correct interval with the specified oil for DPF engines; timing belt and water pump invoices.
- Cold start: knocking, rattles and smoke; on pre-2007 engines listen especially for bearing knock.
- Oil check: level and smell of diesel, which suggests failed DPF regenerations or leaking injectors.
- Diagnostics: EGR, turbo boost, injector corrections, DPF soot load and AdBlue faults on Clio V.
- Test drive: power under load, clutch slip, flywheel judder and gearbox noise.
- Body and interior: driving school or fleet use shows as heavy wear on the driver's seat and pedals.
| Finding | Typical action | Effect on bid |
|---|---|---|
| Belt record missing, mileage past interval | Belt and water pump | Deduct the job |
| Stored EGR or DPF faults | Clean or replace | Deduct; check for oil dilution |
| Clutch slip or flywheel rattle | Clutch kit and flywheel | Deduct; large share of value on cheap cars |
| AdBlue warning (Clio V) | Diagnose pump, heater, sensor | Deduct; car cannot be retailed until fixed |
Are diesel superminis still in demand?
Diesel superminis are still in demand in some markets, but far less than a decade ago. Private buyers in Western Europe have largely moved to petrol and hybrid small cars, while diesel Clios and Capturs still sell well in Italy and to high-mileage drivers and export buyers.
Our data shows this clearly. According to listings tracked by MyCarDealer in eleven European countries in October 2026:
| Model and fuel | Years | Listings | Median price | Median mileage |
|---|---|---|---|---|
| Clio IV diesel | 2014–2018 | 521 | €6,169 | 159,000 km |
| Clio IV petrol | 2014–2018 | 1,229 | €6,950 | 121,000 km |
| Clio V diesel | 2019–2021 | 192 | €9,999 | 105,700 km |
| Captur I diesel | 2015–2019 | 378 | €9,200 | 130,000 km |
Petrol Clio IVs outnumbered diesels by more than two to one and asked about €800 more with lower mileage. Around six in ten diesel Clio IV listings and most Clio V and Captur diesel listings were in Italy. In the Netherlands, diesel Clio IVs asked a median of only €3,950 against €6,900 in Italy. That is an opportunity for cross-border buying if the transport and registration costs work; our article on used diesel demand explains the trend by country.
Low emission zones also matter. In cities that restrict older diesels, a Euro 5 Clio dCi is harder to sell than a Euro 6 car; see our guide on diesel car values and low emission zones.
Pricing diesel Clios and Capturs for stock
Price a diesel Clio or Captur on three factors: generation, mileage and where you will sell it. A car that is hard to sell at home may be easy to sell in a market with stronger diesel demand.
- Clio IV dCi, full history, under 180,000 km: solid budget retail stock in diesel-friendly markets.
- Clio IV dCi, very high mileage: trade or export stock; buy cheaply.
- Clio V Blue dCi: young and economical; check AdBlue and the oil consumption update.
- Captur dCi manual: good family stock; EDC versions only with gearbox evidence.

Frequently asked questions
Is the Clio 1.5 dCi a reliable engine?
Yes, on the Clio IV and V the 1.5 dCi is reliable and often exceeds 200,000 km with correct servicing. Injectors, EGR, DPF, the timing belt and the clutch are the main items to check.
What faults does the Captur 1.5 dCi have?
The Captur shares the Clio's engine faults and adds EDC gearbox issues, DPF problems from short trips, AdBlue faults on Blue dCi models and interior wear. Some 2018–2021 Blue dCi engines also need an oil consumption software update.
Which Clio to avoid?
Be careful with Clio II and III dCi cars built around 2003–2006, which carry crankshaft bearing risk, and with any EDC automatic without gearbox records. Early petrol Clios with the 1.2 TCe 120 also had oil consumption problems.
Are diesel superminis still in demand?
Less than before. In our October 2026 data petrol Clio IVs outnumbered diesels by more than two to one, and most diesel Clio V and Captur listings were in Italy, where demand remains stronger.
What should I check on a high-mileage Clio dCi?
Check the timing belt history, read EGR, DPF and injector data, test the clutch and flywheel and look for diesel in the oil. Price any missing belt record as a job to be done.
