Observe the CVT transmission during acceleration. In cars of this age, it is worth noting if you feel any 'shuddering' or hesitation when pulling away from a standstill, as the Autotronic transmission can exhibit these traits as internal components wear.
Turn the steering wheel from lock to lock while idling. Listen for any whining sounds, as the power steering pump and lines can occasionally show signs of fatigue in the W245 platform.
Operate every single electrical window and the sunroof switch. It is common for the window regulator clips or motors to become temperamental over time due to the frequent use cycles in daily commutes.
Pay close attention to the dashboard for any warning lights, specifically the Check Engine light. The intake manifold air flap motor is a known area that can trigger a light if the plastic linkage has worn.
Consider a full transmission service (fluid and filter) if it hasn't been documented, as fresh fluid helps maintain the longevity of the CVT belt.
Keep an eye on cooling system components; aging plastic connectors and the radiator may start to show signs of brittle wear.
Expect the suspension bushings and ball joints to be nearing the end of their service life, which can affect the smooth handling characteristic of the B-Class.
Ensure the oil has been changed using a high-quality synthetic 5W-30 or 5W-40 that meets Mercedes-Benz approval standards.
Verify that the cabin air filter is clean to keep the climate control system efficient and smelling fresh.
Check the brake fluid condition; moisture buildup over time can impact braking performance in our damp NZ climate.
Look for any small oil dampness around the engine block, as valve cover gaskets are a routine maintenance item that keeps the engine bay tidy.
Confirm the air conditioning blows cold during your check; a quick re-gas or compressor health check can make a big difference on summer road trips.
Estimated repair costs if issues arise
If this component needs attention in the future, it is a specialized job. Budgeting for a professional flush or mechanical inspection now helps avoid larger repair bills later.
Depending on the car's history, you might eventually need to budget for new control arms or bushings if you start hearing knocking sounds over bumps.
If the check engine light appears due to the intake flap linkage, this is a common task for a specialist. It is worth keeping a buffer for this sensor or motor repair.
