0.9L Turbo Petrol - Brabus (80kW)
Petrol
Listen carefully for any jerky gear changes during acceleration; in cars of this age, it is common to consider the health of the twin-clutch transmission as the actuator can occasionally become sluggish.
Turn the steering wheel fully to both locks while stationary to feel for any clicking or binding, as the front suspension and steering components can wear under the city-driving conditions these cars often endure.
Accelerate firmly onto a motorway to verify the turbocharger is spooling smoothly without any whistling or hesitation, as the 0.9L units benefit from consistent maintenance to keep the small turbocharger housing clear.
Check the infotainment and electric windows operate without delay; minor electrical gremlins are occasionally seen in older Smart models, so ensuring all electronic buttons respond crisply is a smart move.
Usually marks the interval where spark plugs and cabin filters should be refreshed to maintain engine efficiency.
A common point where the engine coolant flush and transmission fluid service are recommended to keep the Brabus-tuned engine running reliably.
Often the time to inspect the serpentine belt and tensioner assembly for any signs of aging.
Ensure the oil levels are checked every few thousand kilometres, as the small turbocharged engines can be sensitive to oil volume.
Keep up with the annual service schedule specifically focused on European-spec lubricants to protect the turbo components.
Monitor the tyre condition closely; because these cars use staggered tyre sizes, they wear differently than standard hatchbacks.
Regularly clean out the drainage channels around the doors and roof to prevent moisture buildup in the cabin.
Stay on top of software updates for the transmission control unit if available, as these can significantly improve the quality of shifts over time.
Estimated repair costs if issues arise
If you notice the transmission becoming indecisive, you might eventually need to budget for a recalibration or an actuator refresh to restore that snappy Brabus feel.
Depending on the car's driving history, the wastegate actuator may eventually need adjustment or replacement to maintain consistent boost pressure, which is common for small turbocharged engines.
To keep the handling sharp and predictable as the car ages, it is common to consider replacing front control arm bushings to eliminate road noise and vibration.
