Diesel
Pay close attention to the gear shifts; if you notice any harshness or hesitation, it is worth having a specialist check the 9G-TRONIC transmission fluid condition, as smooth shifting is a hallmark of this model.
Find a quiet road and listen for any knocking or clunking sounds over small bumps, as this can be a sign that the Airmatic suspension components or bushings may be nearing the end of their optimal performance life.
Operate all the infotainment and COMAND system features while parked; occasional software glitches or screen flickering can be common in these systems as they age, so verify everything feels responsive.
Inspect the engine bay for any signs of oil seepage around the V-bank area, as the seals on the intake manifold and turbo area can occasionally show signs of wear in higher-mileage examples.
Consider a proactive transmission fluid and filter service to ensure the 9G-TRONIC continues to shift seamlessly.
A common point to check the condition of the auxiliary belt and pulleys, as well as giving the Airmatic air suspension compressor a quick health check.
Typically the time to inspect the cooling system hoses and radiator integrity to prevent future overheating risks.
Ensure the engine oil and filter are changed every 10,000 to 15,000km using high-quality synthetic oil to keep that V6 running smoothly.
Keep a close eye on the service history to confirm that the AdBlue system has been maintained, as this is vital for your emissions compliance.
Periodically check the tire pressures and tread wear, as the GLE is quite heavy and can be hard on tires if the alignment isn't kept in check.
Every two years, consider a brake fluid flush to maintain crisp braking performance and protect the ABS components.
Don't ignore small electrical warnings; a healthy battery is the heart of the GLE's complex electronic architecture.
Estimated repair costs if issues arise
If the vehicle sits unevenly after being parked for a few days, it may indicate a slow leak in the air struts. It is good practice to keep a reserve for potential repairs as these units age.
These sensors are essential for modern diesel emissions. Depending on the car's history and driving patterns, you might eventually need to budget for sensor replacement if the check engine light appears.
While the 9G-TRONIC is robust, regular maintenance is key to its longevity. If this component hasn't been serviced recently, it is wise to set aside funds to have it refreshed to ensure peace of mind.
