While driving at low speeds, gently turn the steering wheel to both locks to listen for any clicking or grinding sounds from the CV joints, which can occasionally show signs of wear at this age.
Check the CVT transmission health by observing the rev counter during steady acceleration; if you notice any unusual 'hunting' or hesitation, it's worth noting as these units require consistent servicing.
Turn the air conditioning to its coldest setting and verify that the cabin cools down effectively, as the compressor and condenser units in this series can be sensitive to the passage of time.
Before starting the engine, look for any signs of uneven tyre wear, as the W169 suspension geometry can be sensitive to New Zealand road conditions if bushes have aged.
Usually a good time to ensure the transmission fluid has been addressed and that spark plugs have been refreshed.
Consider inspecting the alternator and starter motor for any signs of fatigue, as these are common wear items for vehicles reaching this stage.
Focus on the suspension integrity, including checking shock absorbers and control arm bushings for any perishing rubber components.
Keep a close eye on your engine oil levels between services to ensure the M266 engine remains happy and lubricated.
Ensure the engine coolant is flushed according to schedule, as this helps prevent any long-term issues with the radiator and cooling system.
Regularly clean the drain scuttles near the windscreen to prevent water buildup, which helps keep the cabin air filters and electrical modules dry.
Keep up with regular brake fluid changes, as this is often overlooked but essential for keeping the braking system feeling sharp.
Check your tyre pressures monthly; it's a simple, free way to ensure the car handles safely and saves on fuel costs.
Estimated repair costs if issues arise
If this hasn't been done recently, you might eventually need to budget for a specialized transmission fluid flush to keep the shift quality smooth and reliable.
Depending on the car's history, you might eventually need to budget for replacing worn control arm bushings or ball joints to restore that comfortable Mercedes ride quality.
If this component needs attention in the future, it is worth noting that accessing these parts can be a bit tight in the engine bay, so it's a good idea to set aside a little for potential labour costs.
