2018 Infiniti Q30 2.1L Diesel · BO55 MBH

A persistent tyre degradation trend paired with front suspension component failures defines the mechanical history of this Infiniti, which most recently secured an unconditional pass on 2026-04-17 at 54,842 miles. The vehicle has accumulated a total of eight recorded MOT tests over its lifespan, featuring a notable failure in April 2025 due to split dust covers on both front anti-roll bar linkage ball joints, alongside recurring compound perishing noted on the rear tyres across multiple consecutive annual examinations. While the most recent inspection shows no current defects, the historical record highlights specific mechanical vulnerabilities that require close physical verification during an inspection. Accumulating 54,842 miles over roughly eight years yields an average of approximately 6,855 miles annually, aligning closely with typical UK driving patterns and indicating steady, consistent deployment without extended periods of inactivity. This moderate usage rate suggests that mechanical wear across the drivetrain, steering, and braking systems has progressed at an expected pace for a vehicle of this age, avoiding both the accelerated component fatigue associated with high-mileage commercial use and the potential rubber seal deterioration or battery degradation sometimes triggered by prolonged storage. During the pre-purchase inspection and test drive, specific attention must be paid to the front anti-roll bar drop links that previously failed due to perished dust covers, listening closely for any metallic knocking, clunking, or rattling noises when negotiating speed bumps, sharp turns, or uneven road surfaces. Any suspension play or looseness felt through the steering wheel during cornering will indicate that these drop links or associated anti-roll bar bushes require replacement. Furthermore, the recurring advisories regarding perishing and cracking on both the nearside and offside rear tyres across the 2023, 2024, and 2025 tests necessitate a thorough visual check of the tyre sidewalls and tread blocks for structural integrity and rubber degradation, regardless of the clear status on the latest certificate. Prospective buyers should also inspect the braking system components and underbody shielding to ensure that no secondary wear has been overlooked during previous test cycles.
