Check the timing chain tensioner by listening for a rattle on cold start. | Description: Listen carefully for a brief metallic clatter when the engine first fires up. In these 1.8L engines, the timing chain components can experience wear over time, so it's a good idea to ensure it sounds smooth.
Check this by inspecting the wiring loom near the engine block. | Description: Take a look at the wiring for the camshaft magnets. Sometimes oil can wick into the wiring harness, so checking for any residue or leaks here is a smart move before you commit.
While driving, monitor the gear changes between first and second. | Description: Ensure the automatic transmission transitions are fluid. These units are generally reliable, but checking for any hesitation or 'shudder' is just a standard part of assessing an older Mercedes gearbox.
Check this by turning the steering wheel full lock to full lock while stationary. | Description: Listen for any groans from the power steering pump. It's common for these components to require a bit of attention on older luxury vehicles, so verify the steering feels smooth and quiet.

Estimated repair costs if issues arise
If you notice oil seeping near the front of the engine, it's often these seals starting to tire. It is a manageable fix, but something to keep in mind for your future budget planning.
Over New Zealand's varied roads, bushings and control arms eventually settle. If you notice a knock over bumps, you might eventually need to budget for a suspension refresh to restore that smooth ride.
The Kompressor unit is robust, but if you hear a whine that gets louder with engine speed, it's worth planning for a professional assessment or rebuild to keep the engine performing at its best.
