Engine Weaknesses 2
!! Intake valve carbon build-up from direct injection
As a direct injection engine, the QR25DD does not wash the intake valves with fuel. Crankcase ventilation vapours deposit as oil carbon on the intake valves. Regular cleaning around 80,000–100,000 km is necessary.
Symptoms: Power loss, rough idle, increased fuel consumption, cold start stumble

!! Direct injectors become blocked
The direct injectors of the QR25DD can become blocked through poor fuel quality or extended use. A known issue particularly on early DIG engines. Injector cleaning or replacement required.
Symptoms: Lumpy idle, misfires, poor throttle response, increased consumption
