Cycle through the MBUX infotainment screen and steering wheel controls to ensure the haptic feedback is responsive and the displays aren't flickering or lagging, as these electronic systems can occasionally show glitches.
While driving at low speeds, gently apply the brakes and listen for any squeaks or clicking; the W247 brake systems can occasionally develop minor resonance issues that are worth checking early on.
Accelerate smoothly from a stop to check for any hesitation in the 8-speed DCT gearbox; ensure the shifts feel seamless, as dual-clutch transmissions benefit from smooth, predictable engagement.
Before turning the engine on, inspect the coolant expansion tank for any signs of staining or crusting, as the cooling system seals are best monitored regularly in these M260 units.
Time to consider a transmission fluid flush to keep the DCT shifting crisply.
Often the interval for spark plug replacement to maintain engine efficiency.
A good point to have the water pump and accessory belt inspected by a specialist.
Consider a full diagnostic scan of the electronic control modules to ensure all sensors are communicating correctly.
Keep up with the strict European-spec engine oil change intervals (every 10,000-15,000km).
Ensure the panoramic sunroof tracks, if fitted, are kept clean and lubricated to avoid binding.
Regularly check the tyre tread depth, as the weight distribution in the B-Class can lead to specific wear patterns.
Ensure the 12V auxiliary battery is checked, as MBUX systems can behave erratically if the voltage is low.
Always use genuine or OEM-equivalent brake pads to maintain the factory-feel of the braking system.
Estimated repair costs if issues arise
While the transmission is robust, regular fluid changes are key to longevity. If the car reaches a higher mileage and the shifting feels less crisp, you might eventually need to budget for a professional service to replace the fluid and filter.
In cars of this age, it's common to consider the cooling system as a wear item. If the water pump shows signs of weeping or wear in the future, it is wise to replace it along with the belt to keep everything running cool.
Depending on the road conditions the car has faced, the front control arm bushings may eventually require replacement to maintain that signature Mercedes ride quality. This involves swapping out the rubber components in the suspension arms.
