3.0L I6 Diesel - TD6
Diesel
Turn the steering wheel fully from lock to lock while idling. Listen for groans or clunks from the steering rack, as these components often show their age on L322 models.
Cycle through every air suspension height setting while parked. Ensure the compressor operates quietly and the vehicle levels itself within a reasonable timeframe without dashboard warnings.
Accelerate firmly on an open road to check for smooth gear shifts. If you notice any flaring or hesitation, it is worth considering that the GM-sourced transmission in the TD6 can sometimes show signs of wear as it hits higher mileage.
Check the infotainment and electric seat functions while stationary. It is common for these older electronic modules to act up, so ensure everything from the memory seats to the climate control responds correctly.
Typical interval where air suspension bellows and compressor health should be professionally inspected.
Consideration window for potential timing chain checks and transmission fluid refreshes to maintain longevity.
Major service point where cooling system hoses and thermostat housings are often assessed for fatigue.
Check the service history for regular engine oil changes, as this is critical for the longevity of the TD6 turbocharger.
Inspect the underside for any signs of fluid leaks, specifically around the transfer case and differential seals.
Verify that the battery is in prime condition, as these vehicles are very sensitive to low voltage which can trigger phantom electrical gremlins.
Look for consistent receipts indicating the use of high-quality lubricants and genuine filters.
Ensure the electronic parking brake engages and releases smoothly every single time during your checks.
Estimated repair costs if issues arise
If the vehicle begins to sag overnight or the compressor struggles, it is wise to budget for new air springs or a compressor rebuild to maintain the legendary Range Rover ride quality.
While these transmissions are robust, depending on the car's history, you might eventually need to budget for a torque converter replacement or a full transmission refresh if shifts become sluggish.
In cars of this age, it is common to consider replacing the radiator, water pump, and plastic coolant hoses to prevent overheating and ensure your engine stays reliable on long trips.
