2.0L Turbo Diesel Inline-4 - GLB 220d 4MATIC
Diesel
During the test drive, turn the steering wheel to full lock in both directions | Observation: Listen for any clicking or grinding noises from the front suspension, as the 4MATIC system's axle components can occasionally show wear in high-mileage examples.
Test the MBUX infotainment system thoroughly | Observation: Ensure the dual-screen interface responds promptly to touch and voice commands, as software glitches or processor lag can sometimes occur in earlier X247 models.
Observe the gear shifts while accelerating moderately | Observation: The 8G-DCT dual-clutch transmission should be smooth; jerky shifts in stop-start traffic may suggest the transmission fluid is due for a change or the adaptive learning needs resetting.
Check the panoramic sunroof operation | Observation: Ensure it opens and closes without any stuttering, as the seals and tracks can accumulate debris which may cause strain on the motor over time.
Recommended transmission fluid and filter service to ensure the longevity of the dual-clutch gearbox.
Consider checking the condition of the diesel particulate filter (DPF) if the vehicle has primarily been used for short city trips.
Comprehensive inspection of the suspension bushings, engine mounts, and cooling system hoses.
Verify the service history specifically highlights genuine Mercedes-Benz oil and filters.
Check for a fresh warrant of fitness (WOF) to ensure no underlying structural or mechanical oversight.
Confirm that any outstanding manufacturer recalls have been addressed through an official Mercedes-Benz dealership.
Ensure the AdBlue reservoir is topped up regularly, as this is vital for the emissions system on the 2.0L diesel engine.
Inspect the tire tread depth evenly across all four corners, as uneven wear can indicate a need for a wheel alignment on the 4MATIC system.
Estimated repair costs if issues arise
If the vehicle is used for very short, low-speed commutes, the DPF may eventually require professional cleaning or replacement. Future budget planning ensures you aren't caught off guard if a dashboard warning light appears.
Regular maintenance of the dual-clutch system is essential. If you are approaching the 60,000km service interval, it is wise to set aside funds for a specialized transmission oil flush and filter kit.
While the GLB typically uses a standard setup, depending on the specific options fitted, adaptive dampers can be costly to replace. Keep a modest fund for suspension refreshes as the vehicle ages past 100,000km.
