While idling in Park, listen for any light rattling from the front of the engine, which can sometimes indicate the timing chain tensioner is beginning to show its age in high-mileage examples.
Turning the steering wheel fully from lock to lock while stationary; listen for any whining or groaning noises, as the power steering pumps on these can occasionally require inspection as they age.
Pay attention to the gear shifts, particularly from 1st to 2nd; if they feel hesitant, it's often worth checking if the transmission fluid service history is up to date, as these 7G-Tronic gearboxes appreciate regular attention.
Using the infotainment screen to cycle through all menus and test the electric seat adjustments; electronic gremlins in the SAM (Signal Acquisition Module) units are rare but worth verifying before purchase.
Usually marks the point where suspension bushings may show signs of wear from NZ road surfaces.
The key interval for checking the integrity of cooling system hoses and potential accessory belt replacement.
Often recommended for a comprehensive transmission fluid and filter service to ensure smooth long-term operation.
Ensure you have a complete record of oil changes, ideally every 10,000 to 15,000km, using the manufacturer-approved synthetic specification.
Keep an eye on the coolant levels; keeping the cooling system topped up and healthy is the best way to look after the turbocharger assembly.
Regularly clean the drain holes under the windscreen scuttle to prevent water ingress, which keeps the cabin electronics happy.
Check the tyre pressures regularly, as these cars are quite sensitive to alignment and balance, which helps preserve the suspension components.
Treat the leather and interior plastics with a quality conditioner to keep the cabin looking fresh despite our strong NZ sun.
Estimated repair costs if issues arise
While not a guaranteed failure, it's common to consider this as part of future budget planning for M271/M274 engines. If the cold-start rattle persists, you might eventually need to budget for a preventative replacement to ensure peace of mind.
Some E-Class models come with air struts; if you notice the car sagging after sitting for a few days, it's a sign that the system may need attention. It is wise to set aside funds for air bag or compressor maintenance.
If the previous owner hasn't documented a transmission service, you may want to budget for this soon after purchase. It involves a filter change and fluid flush to keep those shifts silky smooth.
