1.5 dCi K9K

The most-produced small diesel in Europe, shared across Renault, Nissan and Dacia. It's absurdly economical and cheap to fix, and injector wear is the fault that defines it, with a leaking injector able to wash a bore.

Overview

The 1.5 dCi is the K9K diesel version of the Nissan Qashqai crossover (J10), sold 2007–2013 with 106 PS and manual_6. Demands diligence at level 3. Injector wear is the fault that defines this engine, and a leaking injector can wash a bore. 4 failure modes are recorded against its engine, gearbox, chassis and shared components. Prices on this page are illustrative placeholders rather than a sourced market sample. See the methodology for how the bands are derived.

Known issues, ranked by expected cost

Faults recorded against this engine, its components and its chassis, ranked by likelihood × repair cost. Costs are indicative ranges with a stated labour basis.

Warning light, limp mode, oil level rising above the maximum mark from fuel dilution. The filter needs sustained hot running to regenerate. A car used for short urban trips never completes a regeneration cycle.
Check: Read the DPF soot load and the distance since the last regeneration on a scan tool, and check the engine oil level and smell it for diesel. Ask what the car was used for. A short-trip city diesel is the wrong car regardless of mileage.
EmissionscommonPartly detectableevidence: documented120250k km
Injector wear and bore washingK9K 1.5 dCi€400–€1,200
A rough idle, smoke on start-up, uneven running and in the worst case low compression on one cylinder. The injectors wear and can leak, letting combustion gases and fuel past the seat. Left alone, fuel washes the oil film off the bore and damages it, which turns an injector job into an engine one.
Check: Read the injector correction values on a diagnostic and look for one cylinder out of line with the rest. Ask what injector work has been done, because most high-mileage examples have had some.
FuelcommonPartly detectableevidence: documented130230k km
Rear suspension and tailgate wearJ10 body€200–€600
Knocking from the rear over bumps, uneven rear tyre wear, and a tailgate that no longer holds itself up. These carried families and luggage for their whole lives, so the rear bushes and the tailgate struts wear. Ordinary use rather than a design fault, but it turns up on almost every high-mileage example.
Check: On a ramp, lever the rear bushes for play and check the tailgate holds itself open. Look at the inside edges of the rear tyres.
SuspensioncommonPartly detectableevidence: documented110200k km
EGR cooler leakEGR cooler€400–€1,000
Coolant loss with no visible external leak, white smoke, sweet smell. The EGR cooler cracks internally and leaks coolant into the intake. BMW recalled affected diesels over a fire risk from glycol deposits igniting.
Check: Check coolant level and look for unexplained top-ups in the service history. Verify the recall was carried out. It's free and searchable by VIN.

What that meansNo US band exists to compare. Any car you find there's a private import, parts and specialist knowledge are thinner, and the price says more about import cost than about the market.

US figures are the EU band converted at a stated rate. No US market differential is modelled: we hold no sourced US asking prices, and inventing one would be worse than saying so. What the comparison does show for real is availability. Most of this range was never sold in the US.

Buyer notes

Our judgement, kept separate from the records it's built on.

Our read, not a record
The 1.5 dCi is the most common small diesel in Europe, which means parts are cheap and every independent knows it. Economy is remarkable and the engine is simple. What defines it is injector wear, because a leaking injector lets combustion gases past and can wash the bore, which turns a moderate repair into an engine one. So have the correction values read before you buy, ask what injector work has been done, and check the filter history because these do a lot of short trips.

Everything above this line comes from the issue and specification records. This paragraph is our judgement on top of them. See how we reach it.
