2.7L V6 HDi (DT17TED4)
Diesel
Drive until the engine is fully warm, then perform stop-start maneuvers and listen for shifts from 2nd to 3rd gear. | Note: The Aisin AM6 transmission valve bodies are known to fail when hot, causing 'shift shock' or gear flaring, which is an expensive internal repair.
Inspect the 'V' of the engine block with a torch and look for pink or crusty residue. | Note: The plastic thermostat and coolant outlet housings are notorious for cracking; a leak here can lead to rapid overheating and engine failure.
Execute full-lock turns at low speed and drive over speed bumps. | Note: The 2.7L V6 is heavy; front lower swivel joints and wishbone bushings wear prematurely, leading to knocking sounds and uneven tire wear.
Monitor the dashboard for 'Depollution System Faulty' errors during a period of sustained high-gear cruising. | Note: EGR valves and the DPF (Diesel Particulate Filter) frequently clog on cars used primarily for short NZ urban commutes.
Full synthetic oil change (C3 grade) and inspection of the secondary drive belt for signs of fraying.
Replacement of the diesel fuel filter and a partial drain/refill of the automatic transmission fluid to preserve the valve body.
Critical replacement window for the timing belt, tensioners, and water pump; typically recommended every 10 years or 150k km, but earlier in NZ conditions.
Verify Eolys DPF additive fluid levels and refill if necessary.
Inspect the vacuum lines for the twin-turbocharger actuators for perishing.
Check the battery health (CCA) as low voltage causes 'ghost' electrical faults in the BSI module.
Clean the Mass Air Flow (MAF) sensors to prevent sluggish throttle response.
Pressure test the cooling system specifically for the plastic bypass pipe integrity.
Estimated repair costs if issues arise
Preventative maintenance is mandatory to avoid engine destruction; labor is high due to engine bay congestion.
The V6 uses two valves; failure usually results in limp mode and high labor costs for access.
Required if the transmission shifts become harsh; requires specialized diagnostic software to reset adaptions.
