Diesel
Check the air suspension system | Action: Listen carefully while parked. Ensure the vehicle rises and lowers smoothly without the compressor running excessively or sounding overly loud, which could indicate a leak in the struts.
Monitor transmission shifting behavior | Action: During low-speed acceleration, feel for any hesitation or clunky shifts. The 9G-Tronic transmission is generally robust, but it appreciates a fluid change to keep those gear changes crisp.
Verify the operation of the panoramic sunroof | Action: Open and close the blind and the glass roof fully. Any stuttering or unusual noises suggest the tracks may need cleaning or that the motor is working harder than it should.
Inspect for oil seepages | Action: Before and after your drive, have a peek underneath. While minor 'weeping' is common for a vehicle of this age, significant oil presence on the engine block might warrant a closer inspection by a specialist.
Consider a major service including transmission fluid and filter change, even if not explicitly mandated by the service booklet.
Keep an eye on suspension components like control arm bushings, which often start to show signs of wear around this stage on New Zealand roads.
This is a good time to evaluate the cooling system hoses and thermostat to ensure optimal engine efficiency and temperature management.
Prioritize regular oil and filter changes using high-quality synthetic oil to look after the complex turbo systems.
Keep the AdBlue tank topped up to avoid the vehicle entering a 'limp mode' or refusing to start.
Clean and lubricate the panoramic sunroof tracks during your annual service to prevent binding.
Keep your digital service history updated; it makes a huge difference to the vehicle's resale value in the Kiwi market.
Check your brake pad and rotor wear regularly, as the GLE 350d is a heavy vehicle that can be quite demanding on braking components.
Estimated repair costs if issues arise
If the vehicle sits unevenly after sitting for a few days, it is wise to budget for the potential replacement of air struts or the compressor unit.
The Selective Catalytic Reduction system is essential for diesel emissions. Future budget planning should account for potential sensor or pump replacements if warnings appear.
Performing a proper transmission flush ensures longevity. It is a vital piece of maintenance to keep the 9G-Tronic smooth for the long haul.
