1.8L (QG18DE) - Base trim
Petrol
While driving at low speeds, gently turn the steering wheel lock-to-lock to listen for clicking sounds, as CV joints on high-mileage W11s can sometimes show their age through worn boots.
Check this by shifting into reverse and then drive while stopped; a noticeable clunk or delayed engagement can occasionally indicate the transmission mounts might be getting soft with age.
Accelerate firmly on a clear stretch of road to observe the QG18DE engine's smoothness; if you feel a hesitation or stutter, it is worth considering that the ignition coils or mass airflow sensor might be due for a look.
While parked, observe the exhaust on start-up; a puff of blue smoke might suggest that the valve stem seals are beginning to harden, a common trait in older engines that is worth keeping an eye on.
Usually the time to check the engine mounts and ensure the transmission fluid has been refreshed if there is a service history gap.
A good time to inspect the cooling system, particularly the radiator hoses and thermostat, to maintain consistent operating temperatures.
Consider having the suspension bushings checked, as the rubber components can naturally deteriorate over two decades of New Zealand road conditions.
Check the engine oil level and color; the QG18DE engine appreciates fresh oil every 10,000km to keep the timing chain components happy.
Inspect the coolant reservoir for a bright green or blue color, ensuring there are no signs of oily residue.
Check the tire tread wear pattern to ensure the wheel alignment is holding steady, which helps extend the life of your tires.
Test all interior electrics, including the air conditioning, as the climate control systems in the W11 are robust but benefit from regular use.
Look underneath the vehicle for any signs of surface rust, particularly around the rear subframe, which is common for vehicles of this age in coastal areas.
Estimated repair costs if issues arise
In cars of this age, the timing chain tensioner can occasionally lose its firmness, which may lead to a light rattle at start-up. If this starts to become noticeable, it is wise to budget for a professional inspection.
If you notice the ride feeling a bit 'loose' or clunky over bumps, it is often due to the original rubber bushings reaching the end of their lifespan. This involves replacing the control arm bushings to restore that solid, stable handling.
If the history is unknown, it's a great piece of preventative maintenance to have the transmission fluid flushed and the filter cleaned. This helps ensure smooth shifting and protects the gearbox for the long term.
