Dacia Duster
Blue dCi variant of the K9K with AdBlue injection (SCR) for Euro 6 — still a very robust engine. In addition to the regular service schedule, top up AdBlue and keep an eye on the SCR catalyst. Injectors and high-pressure pump remain the typical wear points at high mileages.
Solid diesel engine
The 1.5 dCi with 95 hp is a proven diesel. Economical, strong on torque and long-lived.
Engine Weaknesses 5
Delphi injection system (pre-2006) is particularly troublesome — injectors worn out by 60,000 km. Siemens system (from 2006) is significantly better.
Symptoms: Delphi injection system (pre-2006) particularly problematic — injectors worn out by 60,000 km
Turbocharger can develop play from 60,000 km, especially with short-trip use and no warm-up. Whistling and smoke as symptoms.
Symptoms: Turbocharger can develop play from 60,000 km
Neglected oil changes can cause connecting rod bearing failure — catastrophic engine damage. Regular oil changes every 15,000 km are non-negotiable.
Symptoms: Neglected oil changes can cause connecting rod bearing failure — catastrophic engine damage
DPF clogs when the car is used mostly for short trips. Regeneration fails, engine power is reduced. Regular motorway runs help.
Symptoms: DPF clogs with predominantly short-trip use
EGR valve gets coked up with soot, especially in city traffic. Power loss and increased emissions. Cleaning every 60,000 km recommended.
Symptoms: EGR valve sooted up, especially in city traffic
Vehicle Weaknesses 6
The Duster II also shows axle components with a five-fold above-average defect rate at the very first MOT. Tie rod ends and steering joints are among the most common weak points.
The Duster II brake lines tend to corrode after four years of operation.
A recall was issued for vehicles produced June to July 2023 due to possible cable connector defects that could affect the airbag and drivetrain.
As with its predecessor, the Duster II headlights and tail lights show above-average defect rates at MOT.
Four-wheel drive vehicles develop oil leaks in the transfer case area more frequently after a few years of operation.
The front seats in the Duster II provide little lateral support. Rear seat passengers can slide out of position in corners on the barely contoured bench.
Reports & Tests
At 6–7 years old, nearly one in four has significant defects (23.5% vs. 13.6% average). Main issues: steering joints, lighting, and brakes.
3.7 to 8.4 breakdowns per 1,000 registrations (model years 2017–2020) — green rating. Breakdown frequency acceptable for a budget SUV.
