While cruising on a flat road, check for any 'wobble' or vibration in the steering wheel, as the W210 is known for sensitive front-end bushings and ball joints that may show signs of wear over time.
Check this by shifting the transmission manually through the gears while parked (with foot on brake); look for smooth engagement without any noticeable 'clunk' or hesitation, as the 722.6 transmission relies on a clean electronic valve body.
While the car is idling, observe the dashboard for any flickering pixels in the instrument cluster or information display, as these ribbon cables can become fragile with age.
Check this by turning the steering wheel from lock to lock while stationary; listen for any whining sounds from the power steering pump, which might indicate a need for fluid maintenance or pump attention in the coming years.
Usually the time to evaluate the condition of the engine mounts and transmission mount to ensure vibration-free cruising.
A common point to verify that the spark plugs (12 per engine on the M112 V6) have been serviced correctly.
Consider having a specialist inspect the cooling system components, such as the radiator and hoses, to ensure long-term reliability.
Keep a close eye on the engine oil level and ensure you are using a high-quality synthetic oil to keep the V6 running smoothly.
Periodically check the drain holes around the battery and cowl area for debris to ensure proper water drainage and prevent corrosion.
Ensure the transmission fluid has been serviced or inspected for clarity, as clean fluid is vital for the longevity of the 5-speed automatic.
Regularly inspect the vacuum lines under the bonnet, as they can become brittle and might need replacement to maintain smooth idle quality.
Keep the cabin air filters fresh to ensure the climate control system operates efficiently and keeps the interior comfortable.
Estimated repair costs if issues arise
If the ride feels a bit 'loose' or clunky over bumps, these components may need replacement eventually. It involves replacing the rubber bushings or the entire arm assembly to restore the classic Mercedes ride quality.
If you notice minor shifting irregularities, it is common to check the transmission electrical connector for leaks. Budgeting for a service kit or a minor electronic adjustment can help keep the gearbox shifting seamlessly.
Given the age of these vehicles, the rubber gaskets can sometimes weep oil onto the engine block. It is a very common maintenance task that helps keep your engine bay clean and tidy.
