2.7L (XDi270) - Premium Diesel Turbo
Diesel
While accelerating from a standstill, monitor the gear changes. It is common for the 5-speed Mercedes-derived transmission to experience shift flare or harsh engagement if the transmission fluid has not been serviced periodically.
Cycling through all 4WD modes while stopped in neutral. You should hear the transfer case engage promptly; hesitation or warning lights on the dash might suggest the vacuum-operated front hub locking system needs inspection.
Listen closely for any rhythmic knocking or clunking from the front end over bumps. The lower ball joints and control arm bushes often show signs of wear on these heavy SUVs after significant road use.
Observe the cold start sequence. If there is significant white or blue smoke upon ignition, it is worth considering a professional pre-purchase inspection to rule out injector seal degradation or worn turbo seals.
Usually the time to evaluate the condition of the water pump and serpentine belt tensioner.
A common interval to check the timing chain tension and ensure the diesel particulate filter system (if equipped) or exhaust components are clear.
Often the point where original suspension struts may require replacement to maintain a comfortable ride quality.
Regularly replace the fuel filter every 10,000km to protect the sensitive common-rail injection system from New Zealand's varied diesel quality.
Keep an eye on the coolant level and ensure the cooling system is flushed with the correct specification fluid to prevent internal corrosion.
Apply a light silicone spray to the rubber seals around the door frames and sunroof to keep them supple and prevent annoying rattles.
Ensure the transmission fluid is changed every 60,000km, even if the manual suggests a longer interval, to keep the gear changes smooth.
Check the condition of the vacuum lines under the bonnet, as they can become brittle with age and heat exposure.
Estimated repair costs if issues arise
In cars of this age, the vacuum lines operating the turbocharger can perish. If the car feels sluggish or goes into limp mode, you might eventually need to budget for a vacuum system overhaul.
The 2.7L engine is quite robust, but injector seals can wear over time. If you notice a 'chuffing' sound or smell diesel fumes in the cabin, it is a good idea to set aside funds for professional injector servicing.
Given the vehicle's weight and potential use for towing, the front suspension bushes and ball joints will eventually need attention to maintain WOF standards and handling precision.
