While idling in park, listen for any rough shaking or misfires, as the ignition coils on these W168 models can occasionally show their age after many years on the road.
Turning the steering wheel slowly from lock to lock while stationary to feel for any binding or strange noises, which may indicate the steering rack or associated linkages are ready for a refresh.
Perform a few low-speed gear changes, paying close attention to whether the semi-automatic or manual transmission engages smoothly without any hesitation or unusual clunking sounds.
Inspecting the underside of the engine bay for any signs of oil seepage or coolant dampness, as older gaskets and hoses in these compact layouts can sometimes develop minor leaks over time.
Usually the time to ensure the auxiliary drive belt and tensioner have been inspected or replaced to prevent cooling system issues.
A common point where the suspension bushings and ball joints may start to show signs of wear, potentially affecting the car's handling feel.
Consider a thorough inspection of the cooling system components, including the radiator and thermostat, to ensure continued reliability.
Keep a consistent log of oil and filter changes every 10,000km to keep that M166 engine running as sweetly as possible.
Regularly check your coolant levels; keeping the system clean and topped up is a great way to avoid unnecessary stress on the engine components.
Ensure the cabin air filter is replaced annually to keep the ventilation system fresh and efficient for those damp New Zealand mornings.
Give the exterior rubber seals a quick wipe-down with a silicone-based treatment to prevent them from drying out and cracking in our harsh sun.
Monitor the brake fluid colour and condition; flushing the system every two years will keep your stopping power consistent and reliable.
Estimated repair costs if issues arise
If the car develops a persistent misfire, it is quite common to consider replacing the coil pack. It involves sourcing a high-quality unit to ensure smooth running for years to come.
Given the age of these vehicles, you might eventually need to budget for a suspension refresh to restore that 'solid' Mercedes ride feel if you notice any knocking over bumps.
Because the engine bay is quite compact, labor can be a factor. Should the alternator or the complex belt tensioner system require attention, it is wise to set aside some funds for the specialist time required.
