4.5L (1VD-FTV) V8 Twin-Turbo Diesel - Luxury/Limited trim
Diesel
Check the transmission shift quality by gently accelerating from a stop. | Description: While driving, pay attention to the 6-speed automatic gearbox; it's common for these high-torque V8s to exhibit some hesitation or 'flare' if the transmission fluid hasn't been serviced, so ensure the changes feel smooth rather than jerky.
Check the suspension responsiveness by toggling through the AHC (Active Height Control) settings. | Description: While stationary, raise and lower the vehicle; in cars of this age, it's worth noting that the hydraulic spheres can eventually lose pressure, so listen for any unusual wheezing or sluggishness in the system.
Check the underside and engine bay for any oil residue around the 'valley' area. | Description: It is worth inspecting the engine valley for signs of oil or coolant pooling, as the twin-turbo setup creates significant heat, which can occasionally lead to brittle seals over many years of operation.
Check the infotainment and dashboard electronics by operating every button and screen function. | Description: In cars of this generation, the complexity of the onboard systems means that individual modules might occasionally fail; ensure everything from the seat ventilation to the Mark Levinson audio responds promptly.
Usually a key point for a comprehensive transmission fluid flush and an inspection of the turbo intake hoses.
A common interval for checking the AHC hydraulic fluid levels and inspecting the condition of the brake rotors and heavy-duty suspension bushes.
A good time to review the cooling system, including replacing the water pump and thermostat to ensure the 1VD-FTV engine maintains optimal thermal efficiency.
Prioritize engine oil and filter changes every 10,000km to protect the twin-turbo bearings.
Regularly clear out the cabin air filter to keep the luxury interior environment fresh.
Have the AHC system checked for fluid leaks during every major service interval.
Monitor the wheel alignment closely, as the heavy weight of the vehicle can wear tyres unevenly if left unchecked.
Keep a consistent log of your fuel filter changes, as the common rail injection system performs best with clean diesel supply.
Estimated repair costs if issues arise
Future Budget Planning: These components act as the 'springs' for your hydraulic suspension. Depending on the car's history, you might eventually need to budget for a replacement if the ride quality becomes noticeably firm or bouncy.
Future Budget Planning: The 1VD-FTV is a robust engine, but the twin-turbo setup is sophisticated. If you notice a loss of power or excessive smoke in the future, the cost to overhaul or replace the turbochargers is significant.
Future Budget Planning: Given the size of the LX, the braking system works hard. If this component needs attention, you'll be looking at larger premium rotors and pads which are essential for safety.
