2015 Mercedes-Benz GLA 2.1L Diesel · FH65 PCZ

The latest MOT test on 2026-02-05 resulted in a passing outcome, though it revealed persistent tyre wear advisories on both the nearside and offside front tyres, each approaching the legal limit with edge wear indicative of uneven or excessive lateral forces. While this is not a failing condition, the recurrence of these advisories over the past three years suggests a pattern that warrants attention. The two prior failures in 2024-06-11 and 2025-06-17, both marked by coil spring fractures on the rear offside and nearside respectively, highlight a critical structural wear issue that has not been resolved. The vehicle’s maintenance history does not show a clear improvement, with advisories on brake discs and rear brake pads persisting, alongside recurring tyre sidewall damage. These findings imply either underlying suspension or alignment problems contributing to the tyre wear, or potentially neglected maintenance of the braking system. The recorded mileage of 81,297 miles for a vehicle aged approximately 11 years represents a moderate annual usage rate of around 7,391 miles, which is within the expected range for this class of car. However, the gaps between MOT tests—particularly the two-year interval between 2023 and 2025—suggest periods of either underutilisation or prolonged static storage, which can accelerate wear in components like brakes, tyres, and suspension. Standing vehicles are particularly susceptible to corrosion in brake systems, particularly the rear brake pipes, which the 2021 MOT noted as corroded and greased. Additionally, the absence of service records or a service book beyond the MOT history may indicate that consumable items like brake fluid, coolant, and transmission fluid have not been replaced at recommended intervals, risking degradation over time. The high mileage has likely contributed to wear on the drivetrain, suspension, and internal engine components, though the specific failures recorded have been limited to the rear coil springs and tyres. To proceed with a thorough inspection, the prospective buyer should prioritise checking the suspension and alignment for signs of persistent uneven tyre wear, which may indicate misaligned wheels, warped suspension bushes, or binding calipers. Listen for clunks or rattles during cornering, particularly on the rear, as these could signal coil spring or mounting failure progression. Inspect the front and rear brake systems for binding calipers, warped discs, or excessive brake fluid contamination, which could exacerbate the noted disc wear. The corroded rear brake pipes should be thoroughly cleaned and inspected for structural integrity, with any grease or debris removed to prevent further corrosion. On the test drive, monitor for brake shudder, uneven stopping distances, or a spongy pedal feel, which may indicate warped discs or failing brake pads. Additionally, verify the steering wheel for excessive play, which could relate to worn suspension linkages or steering rack issues. For practical checks beyond the MOT, the buyer should examine the tyres for sidewall cracking or perishing, which can occur even at moderate mileage due to age-related degradation. Check the tyre tread depth for consistent wear patterns and ensure no sidewall damage has progressed beyond the advisory limits noted in the MOT history. Inspect the battery terminals for corrosion or loose connections, and test the 12V battery’s charge capacity, as prolonged static periods can lead to battery failure. Fluid levels should be checked, with coolant, brake fluid, and transmission fluid replaced at the manufacturer’s recommended intervals, even if the vehicle has been driven regularly. Finally, verify that the service book or maintenance records have been updated, as the absence of such documentation suggests potential neglect of time-based maintenance tasks, which are critical for the long-term reliability of the vehicle.
