2.2L HDi (DW12CTED4)
Diesel
Perform repeated manual upshifts and downshifts using paddle shifters once the car is hot, focusing on the 2-3 and 3-2 transitions. | Note: The heavy torque (450Nm) of the GT's 2.2L engine accelerates valve body wear in the Aisin AM6 automatic transmission, leading to aggressive thumping shifts.
Drive over speed bumps and sharp road imperfections while listening for knocking or creaking from the front axle. | Note: The 2.2L GT model features a unique and highly expensive double-wishbone front suspension setup (drop links, hub carriers) which costs far more to repair than standard models.
Accelerate hard on a motorway on-ramp and look for an immediate 'Anti-Pollution System Faulty' message on the center screen. | Note: The DW12 engine is highly susceptible to EGR valve soot blockage and DPF clogging if the vehicle was primarily driven on short NZ school runs or city trips.
Test all functions of the RT6 infotainment system, including the retractable HUD (Head-Up Display) screen on top of the dash. | Note: The HUD mechanism can jam or stripped gears can cause it to stutter. The head unit itself suffers from internal flash memory failure over time.
Standard synthetic oil change (5W30 C2/C3 Low SAPS spec) and multi-point safety inspection, focusing on heavy front brake wear.
Major service including replacement of the main diesel fuel filter (critical for common-rail high-pressure pump longevity) and brake fluid flush.
Critical timing belt, tensioner, and water pump replacement. Though factory intervals state longer, NZ specialists recommend 100k to prevent failure.
Verify Eolys DPF additive fluid level; a low warning generally triggers between 100,000km and 120,000km on these GT models.
Check for visible oil leaks around the turbocharger oil return pipes and the main plastic cam/valve cover gasket.
Inspect the condition of the serpentine accessory belt and the dampened crankshaft harmonic balancer pulley for rubber separation.
Confirm the cooling fan slow-speed resistor is fully operational; failure causes the car to run dangerously hot in city traffic.
Ensure the electronic parking brake (EPB) cables and actuator release smoothly without binding or screaming under strain.
Estimated repair costs if issues arise
Strict preventative maintenance requirement to avoid catastrophic piston-to-valve damage upon belt snap.
The standard fix when the Aisin AM6 gearbox begins shifting violently when hot; requires specialist transmission rebuilding.
Unique suspension components exclusive to the 2.2L GT variant; parts must often be sourced directly from Europe.
Required if the diesel particulate filter is heavily loaded with ash beyond the capabilities of a forced diagnostic regeneration.
