Listen during gear shifts while accelerating at low speeds. | Note: The 9G-TRONIC transmission is generally robust, but some users have noted occasional hesitation. In cars of this age, it is worth ensuring the shifts feel smooth rather than jerky.
Check for signs of air suspension 'sag' after the car has been parked. | Note: Check this by observing if one corner sits lower than the others. Air struts can naturally wear over time, so verify that the system raises the vehicle level without excessive compressor noise.
Inspect the front footwell carpets for any dampness. | Note: Ensure the sunroof or windscreen seals are keeping the cabin dry, as dampness can sometimes indicate blocked drain tubes which are a common maintenance area for W166 models.
Turn the steering wheel fully to the left and right while stationary. | Note: Listen for any whining from the power steering pump or knocking from the suspension bushings, as these components may show wear depending on the vehicle's history.

Ask the seller for records confirming that the brake fluid has been flushed every two years.
Ensure the AdBlue system has been serviced or topped up appropriately to prevent any startup warnings.
Regularly clean out the sunroof drain holes to prevent internal moisture build-up.
Keep a close eye on your coolant levels, as checking this periodically helps identify small leaks before they become larger issues.
Estimated repair costs if issues arise
If the vehicle is equipped with AIRMATIC, it is common to consider that these struts may eventually need replacement due to rubber fatigue. Future budget planning of around this amount per corner is wise.
The 9G-TRONIC gearbox benefits from fresh fluid to maintain smooth gear changes. Depending on the car's history, you might eventually need to budget for a full fluid and filter service.
As a diesel engine, the DPF can accumulate soot over high mileage. If the car has primarily been used for short city trips, it is common to consider a professional DPF clean or replacement as a future maintenance item.
