2015 Mercedes-Benz A-Class 2.1L Diesel · LL65 LHA

The most recent MOT test on 2026-05-01 resulted in a failure due to a critical tyre defect—specifically, the near-side rear tyre exhibiting a cut reaching the ply or cords and exceeding the legal limit, alongside severe wear at the inner edge. This failure follows a pattern of recurring advisories and minor issues over the past three years, indicating a maintenance trend that has not stabilised. While earlier MOTs in 2025 and 2024 recorded only advisories related to brake pad and disc wear, the 2026 failure underscores a deterioration in tyre integrity, which is a non-negotiable roadworthiness requirement. The presence of the same offside rear coil spring corrosion and near-side front anti-roll bar linkage ball joint deterioration from 2026-05-01 suggests underlying mechanical wear that may have progressed despite prior advisories being addressed. This suggests either inadequate past maintenance or gradual component failure, warranting immediate attention to prevent further degradation. The vehicle’s recorded mileage of 97,585 miles at the time of the latest failure represents a typical annual usage rate of approximately 8,871 miles, which is consistent with a moderately driven car over its 11-year lifespan. There is no evidence of extreme mileage accumulation or unusual wear patterns that would suggest high-stress operating conditions, such as heavy towing or aggressive driving. However, the steady mileage accumulation over the years implies consistent usage, which accelerates wear on consumables like brakes, tyres, and suspension components. The absence of significant mileage gaps—particularly in the past three years—may also mean the vehicle has been in regular use, potentially contributing to the observed tyre failure and recurring advisories on brake systems and suspension elements. Given the critical tyre failure and recurring advisories, the prospective buyer must prioritise an immediate inspection of the tyre condition, particularly the near-side rear tyre, which is now legally non-compliant. Look for signs of further ply or cord exposure, uneven wear patterns, or evidence of recent cuts or bulges. During a test drive, monitor for excessive road noise or vibration from the rear wheels, which could indicate misalignment or suspension misalignment contributing to uneven tyre wear. The offside rear coil spring corrosion and near-side front anti-roll bar linkage ball joint deterioration require further investigation, including visual checks for fluid leaks from the ball joint and listening for clunking noises from the suspension during cornering or over bumps. If the coil spring is severely corroded, it may need replacement, and the anti-roll bar linkage should be serviced or replaced to prevent further deterioration of the suspension system. For the brake system, which has shown recurring thin pad wear and pitted discs, the buyer should verify the condition of all brake pads, discs, and calipers. Listen for abnormal brake pedal feel—such as sponginess, softness, or binding—during a test drive, as these can signal caliper binding or warped discs. Check for uneven brake disc wear or scoring, which may indicate misalignment or hydraulic issues. Given the age of the vehicle, it is prudent to inspect the brake fluid for contamination or moisture, as this can lead to brake failure. Additionally, the buyer should consider a comprehensive fluid check, including power steering, differential, and transmission fluids, as these degrade over time and can exacerbate mechanical issues. Finally, while the mileage is moderate, the vehicle’s age means it is susceptible to issues like tyre sidewall perishing, which should be checked for cracks or dry rot, especially if the tyres have been stored for extended periods. A thorough inspection of the 12V battery and starter motor is also recommended, as standing vehicles can suffer from corrosion and reduced electrical efficiency.
