2.2L (OM651) Turbo Diesel - Premium
Diesel
Check the transmission shift quality | Description: While driving, pay close attention to the 7-speed automatic transmission. In cars of this age, it is common to consider that harsh gear changes, especially at lower speeds, may indicate the need for a software update or a transmission fluid flush.
Listen for turbocharger performance | Description: Check this by accelerating firmly on an open road; if you notice a lack of 'punch' or a persistent whine, it's possible the OM651 turbo system could be showing signs of wear due to its high-pressure nature.
Test the steering response | Description: When maneuvering at low speeds, observe the steering feedback. Some Q50 models feature Direct Adaptive Steering (steer-by-wire); it is worth ensuring there are no warning lights, as system sensors can occasionally trigger service requirements as they age.
Inspect the infotainment system responsiveness | Description: Check this by cycling through the dual-screen interface; these early systems can sometimes experience minor 'lag'. Ensure both screens respond promptly to touch, as intermittent connectivity can be a known trait in early V37 production runs.
Consider a full cooling system refresh and inspection of the DPF (Diesel Particulate Filter) health.
A common point to evaluate the condition of suspension bushings and engine mounts for any signs of perishing.
Ideally, have the timing chain assembly and ancillaries inspected by a specialist to ensure long-term reliability.
Prioritize oil changes every 10,000km using high-quality synthetic oil specifically rated for the OM651 engine.
Regularly clean the DPF by taking the car on longer highway drives to prevent soot buildup.
Check the condition of the battery regularly, as these cars are sensitive to voltage drops which can affect electronic sensors.
Keep the cabin air filter fresh to protect the interior electronics and ensure good climate control performance.
Inspect brake rotors and pads every service, as the Q50 is a heavier vehicle that uses its stoppers quite effectively.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is reflective of professional cleaning or a full unit replacement depending on the level of blockage.
Depending on the car's history, you might eventually need to budget for the replacement of control arm bushings or shocks to restore that smooth Infiniti ride quality.
If the touch-sensitive layers on the dual screens begin to fail, it is helpful to set aside funds for potential replacement modules or specialized electrical repair.
