GLE 350 d 3.0L V6 Diesel
Diesel
Observe the transmission at low speeds; check if the 9G-TRONIC gear changes feel smooth, as occasionally these can exhibit slight hesitations which may benefit from a software update.
Navigate over uneven surfaces or speed bumps to listen for any knocking sounds from the suspension, as the air suspension (Airmatic) components can experience wear over higher-mileage cycles.
Ensure the infotainment and Command system functions are responsive, as older electronic modules can occasionally act up after years of use in NZ's temperature fluctuations.
Spend time parked with the engine running to check for any faint sweet smells or signs of coolant loss, as the cooling systems in V6 diesels can sometimes develop minor leaks at this stage in their lifecycle.
Consider a full transmission fluid service to maintain shift quality and prevent long-term wear.
The DPF (Diesel Particulate Filter) may begin to require more frequent active regeneration cycles; ensure the car is taken for regular highway runs.
Inspect suspension bushes and air bellows, as these parts often start showing signs of fatigue by this point.
Check the service log for proof of regular oil changes using the correct Mercedes-approved low-ash synthetic oil.
Verify that the AdBlue system is operating correctly and hasn't been bypassed or disabled.
Ensure the panoramic sunroof tracks are cleaned and lubricated to prevent sticking or noise.
Check the condition of the brake rotors and pads, as the GLE is a heavy vehicle and consumes these quite reliably.
Examine the engine bay for any oil seepage around the turbo intake seals, which is a common area to monitor.
Estimated repair costs if issues arise
If the vehicle sits unevenly after being parked for a few days, you might eventually need to budget for the replacement of one or more air struts. It's a standard wear-and-tear item for high-end SUVs as they age.
While the 9G-TRONIC is a robust unit, regular fluid flushes are key to its longevity. If this hasn't been done, it's worth keeping a buffer for a proper specialist flush.
Modern diesel engines rely on various sensors to manage emissions. Depending on the car's history of short vs. long trips, you might need to budget for sensor replacements or a professional DPF clean.
