Test Drive Task: Listen for DCT gearbox hesitation. | Note: During low-speed city driving or slow-speed manoeuvres, observe if the 8-speed dual-clutch transmission shifts smoothly. It is common for these systems to feel slightly hesitant or 'clunky' when cold; ensure you feel comfortable with its operation.
Test Drive Task: Cycle through the MBUX infotainment features. | Note: Spend a few minutes ensuring the dual-screen setup and MBUX system respond promptly. In cars of this generation, occasional software glitches can occur, so checking that all touch-pads and voice commands function correctly is a wise step.
Test Drive Task: Inspect the panoramic sunroof seals. | Note: While parked, check the perimeter of the sunroof for any signs of water staining or dampness in the headliner. It is good practice to ensure the mechanism operates silently through its full range of motion.
Test Drive Task: Verify the electronic parking brake operation. | Note: Engage and disengage the brake several times while stationary. Confirm there are no warning messages on the instrument cluster, as this system relies on precise electronic sensors.
Time to consider a transmission fluid flush and initial brake pad inspection.
The major service point usually involving spark plug replacement and a thorough inspection of the all-wheel-drive system.
A common interval to check suspension bushings and potential coolant system pressure tests.
Verify the service history specifically highlights the use of Mercedes-Benz approved engine oil.
Regularly inspect tyre tread depth, as the AMG performance tune can lead to faster wear than standard GLB models.
Keep the MBUX software updated by checking with a local specialist or dealer during routine visits.
Ensure the cabin air filter is replaced annually to keep the climate control system operating efficiently.
Check the coolant levels regularly to ensure there are no signs of leaks in the high-pressure turbo cooling lines.
Estimated repair costs if issues arise
As an AMG variant, the braking system is designed for high performance. Depending on your driving style, you might eventually need to budget for a full set of pads and rotors.
To maintain the sharp handling characteristic of the GLB 35, you might eventually need to budget for control arm bushings or damper checks as the vehicle clocks up higher mileage.
If this component needs attention in the future, performing a comprehensive fluid and filter service is a great way to ensure longevity. It is worth setting aside funds for this every 60,000km.
