Test drive task: Start the engine from cold and listen for a rattling noise from the front of the engine. | Detail: It is worth investigating the timing chain and tensioner, as in high-mileage W211 examples, these can show signs of wear over time.
Check this by: Pressing every button on the dashboard and center console during your stationary inspection. | Detail: Electronic gremlins can occasionally appear in the SAM (Signal Acquisition Module) units, so ensuring all features function as expected is a smart move.
While driving: Pay close attention to how the transmission shifts between first and second gear. | Detail: The 5-speed automatic gearbox is generally robust, but checking for smooth transitions helps confirm that the valve body and electronics are performing consistently.
Check this by: Inspecting the footwell carpets and the boot area for any signs of dampness. | Detail: It is worth being mindful of potential drainage blockages, which can cause water ingress in cars of this age if the sunroof or cowl drains haven't been cleared.
