2.7L (XDi) - RX270 XDi Diesel
Diesel
Observe the gear shifts when cold; ensure they are smooth, as the Mercedes-sourced 5-speed automatic can experience solenoid issues if the transmission fluid hasn't been serviced regularly.
Engage the 4WD selector on a loose surface to ensure the transfer case shifts cleanly and the electronic engagement doesn't stick or throw an error light on the dash.
Listen for any excessive rattling or clatter from the engine bay at idle, as these 2.7L diesel engines can occasionally show early signs of timing chain tensioner wear.
Navigate over a series of speed bumps and listen for any clunking or knocking from the front suspension, noting that the ball joints and lower control arm bushes are common areas for wear given the vehicle's heavy kerb weight.
Consider a full cooling system flush and inspection of all hoses, as the ageing plastic components can become brittle.
Inspect the condition of the turbocharger and intercooler hoses for signs of oil weeping or reduced boost efficiency.
Review the history for a timing chain service and check the fuel injectors for consistent spray patterns to maintain engine longevity.
Prioritize regular engine oil and genuine filter changes every 10,000km to protect the turbocharger.
Keep a close eye on the transmission fluid colour and smell; it is often neglected but critical for the health of the RX270's gearbox.
Check the underside regularly for any surface rust, especially if the vehicle has been used for towing or beach access.
Ensure the cooling system is topped up with the correct specification coolant to avoid internal corrosion.
Regularly lubricate the chassis grease points if you are using the Rexton for off-road duties to keep the suspension components happy.
Estimated repair costs if issues arise
If the gearbox starts feeling 'lazy' or hesitant, a fluid flush and potential solenoid pack replacement is a wise move for long-term health. Future Budget Planning: It is prudent to set aside funds in case a transmission specialist is needed to sort out shifting irregularities.
Given the Rexton's weight, the front suspension bushings and ball joints are considered wear-and-tear items. Future Budget Planning: Should you notice uneven tyre wear or handling vagueness, prepare for a refresh of the front-end components.
As these diesels age, the rubber boost hoses can develop microscopic cracks. Future Budget Planning: Should you experience a sudden loss of power or increased smoke under load, these hoses are the first things to check.
