While driving at low speeds, gently apply the brakes to check for any vibrations or 'clicking' noises, as early W246 models may show signs of premature front suspension bushing wear.
Before turning the engine over, shift through all gears while stationary and then perform a slow-speed crawl to ensure the 7G-DCT transmission shifts smoothly without hesitation or shuddering.
While parked, toggle through all infotainment menus and climate control settings; ensure the central display is clear and that the dash buttons aren't feeling sticky, as these units can occasionally experience minor electronic glitches.
Open the bonnet while the engine is running and listen closely for any high-pitched rattling from the top end, as the M270 engine timing chain tensioner is something to be aware of if maintenance records are thin.
Usually marks the point where the 7G-DCT transmission fluid is due for a service to ensure long-term longevity.
Often the time to inspect cooling system components, specifically the water pump and thermostat housing, which can start to weep at this stage.
A common window to look at refreshing the suspension components and checking the auxiliary drive belt and pulleys.
Verify that the service history shows regular oil changes using high-quality synthetic oil, as these turbo engines prefer fresh lubrication to keep the internal components happy.
Ensure the air conditioning system is blowing cold; checking the pollen filter cleanliness is a quick win for cabin comfort.
Take a peek at the tyre wear patterns to ensure the alignment is true, as even-wearing tyres are a good sign of a well-cared-for vehicle.
Confirm the brake fluid has been replaced every two years, as this is vital for keeping the braking system responsive and safe on our twisty Kiwi roads.
Check for any signs of dampness in the footwells, just to make sure the sunroof drains (if equipped) are clear and doing their job.
Estimated repair costs if issues arise
In cars of this age, it's common to consider the plastic cooling system components. If this component needs attention in the future, it involves replacing the housing to prevent potential coolant leaks.
Depending on the car's history, you might eventually need to budget for a transmission service to keep those gear changes crisp and responsive.
New Zealand roads can be tough on suspension. If you notice a knock or a loose feeling in the steering, you may need to budget for fresh bushings and a wheel alignment.
