Renault Clio: 1.5 dCi injector and DPF/EGR problems
1.5 dCi injector and DPF/EGR problems is a common engine fault on the Renault Clio on the 2013–2019 cars, and we rate it major. Putting it right costs $700 to $2,500 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 15 documented faults on the Renault Clio.

What you are looking at
A common-rail diesel injector. Contamination damages the nozzle at the tip.
What goes wrong
The 1.5 dCi (K9K) diesel carries over its known injector weakness into the Clio IV, with worn injectors causing hard hot-starting, idle knock and black smoke. Cars used mainly for short town trips also suffer diesel-particulate-filter (DPF) blockage and EGR-valve clogging, showing as reduced power, a DPF warning light and limp mode. A good motorway run can clear a partly blocked DPF, but a fully blocked one or worn injectors are costly.
What you would notice
- Hard hot-starting and idle knock
- Black smoke and power loss
- DPF or engine warning light
- Limp mode after mostly short trips
How to check it
Where to look. Top of engine (injectors); exhaust line (DPF); intake side (EGR valve)
Ask how the car is used – a short-trip town car is more likely to have a clogged DPF.
On the drive check it pulls cleanly without smoke or limp mode, and confirm it starts promptly hot.
Look for a DPF or glow-plug light on the dash and ask for injector/DPF history.
What it costs to put right
$700 to $2,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Is this car mostly used for short town trips or longer runs?”
- “Have the injectors, EGR valve or DPF ever needed work?”

How much does it cost to fix on a Renault Clio?
$700 to $2,500 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Renault Clio years are affected?
Our research records this fault on the 2013–2019 Renault Clio. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
How do I check for it before I buy?
