2.6L V6 (M112) - E240 Elegance/Avantgarde
Petrol
Check this by turning the steering wheel from lock to lock while stationary, listening for any groaning or uneven resistance in the power steering pump, which is common as these aging systems accumulate wear.
While driving at a steady speed, gently rest your foot on the brake pedal to feel for any shimmy or vibration, as the W210 suspension bushings and lower ball joints can experience play after many years of use.
During your test drive, observe the transmission shifting behavior; ensure it moves between gears smoothly without hesitation, as these older 'sealed-for-life' transmissions can benefit from fluid changes if they haven't been performed previously.
Check this by toggling all interior climate control settings; ensure the heater core and air conditioning system engage properly, as the vacuum-operated flaps and HVAC modules can occasionally become sluggish in older Mercedes models.
Usually the time to evaluate the health of the engine mounts and transmission mount, as these rubber components can perish over time, leading to increased cabin vibration.
A common point to review the ignition system, specifically the spark plugs and coil packs, as the M112 V6 engine has dual-spark ignition that requires consistent maintenance for optimal fuel efficiency.
Consider inspecting the cooling system components, including the radiator and water pump, to ensure the plastic housings remain resilient for future motoring.
Verify that a record of transmission fluid services exists, as fresh fluid helps maintain the long-term longevity of the 5-speed automatic gearbox.
Inspect the undercarriage for any signs of surface rust, particularly around the jacking points and wheel arches, which is a consideration for vehicles of this era in NZ conditions.
Confirm the secondary air injection system is functioning, as this helps the engine meet emissions standards during cold starts.
Ensure all digital pixels on the dashboard instrument cluster are clear, as the ribbon cables in the W210 clusters can occasionally fail or fade over time.
Check the condition of the serpentine belt and the tensioner pulley to ensure the accessory drive system is operating quietly and efficiently.
Estimated repair costs if issues arise
As these vehicles age, the rubber components in the suspension may eventually show signs of fatigue, impacting the ride comfort. Depending on the car's history, you might eventually need to budget for a refresh of the front control arms or ball joints to restore that classic 'Benz' ride quality.
If you notice a slight burnt oil smell or minor seepage around the engine bay, it is common to consider replacing the valve cover gaskets. This is a standard maintenance task for the M112 V6 as seals harden with age.
If this component needs attention in the future, it is wise to address the radiator, water pump, and thermostat housing together to ensure reliability. It is a prudent bit of future budget planning for any high-mileage German vehicle.
