2016 Mercedes-Benz A-Class 1.5L Diesel · GA55 LAN

The most recent MOT test on 2026-01-09 resulted in a passing grade, but it was accompanied by two significant advisories regarding the nearside and offside front tyres, each showing wear approaching the legal limit and exhibiting edge wear patterns indicative of uneven loading or directional imbalance. This follows a pattern of recurring advisories on tyre condition from previous MOTs in 2019 and 2023, suggesting a persistent issue with tyre performance that has not been fully resolved despite passing tests. The vehicle also failed in 2024-12-11 with major defects related to the anti-roll bar ball joint dust covers, which are critical for preventing dirt ingress and maintaining suspension integrity, alongside a critical airbag inoperability that must be addressed immediately. While the 2023 and earlier MOTs were clean, the presence of these recurring issues—particularly the airbag failure—demonstrates a concerning maintenance trend where critical components have either been neglected or have failed to meet safety standards. The recorded mileage of 251,314 miles for a vehicle aged approximately ten years represents an annual usage rate of around 25,131 miles, which is exceptionally high for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and fluid systems, as well as on structural elements like the anti-roll bars and tyres. The rapid mileage suggests either heavy, frequent use or a lack of adequate maintenance intervals, both of which can lead to premature failure of high-wear items. The absence of significant mileage gaps between MOTs implies consistent driving, which may have contributed to the observed tyre wear patterns and the deterioration of suspension components like the anti-roll bar ball joints. This level of usage also increases the likelihood of hidden issues such as internal tyre damage, brake pad or rotor wear beyond the visible surface, and potential fluid degradation from prolonged operation without servicing. Given the vehicle’s high mileage and the recurring MOT advisories, the prospective buyer should conduct a thorough inspection of the suspension system, focusing on the front anti-roll bars and ball joints. During a test drive, listen for unusual clunking or rattling noises from the front suspension, particularly when driving over bumps or at low speeds, as these could indicate failing ball joints or worn suspension bushes. Inspect the tyres closely for signs of uneven wear beyond the advisories—such as cupping, feathering, or internal damage—and measure their depth to ensure they remain above the legal minimum. Check for any fluid leaks under the vehicle, particularly around the anti-roll bars, brakes, and exhaust system, as these could reveal issues with seals or gaskets that may have contributed to the MOT failures. Additionally, verify the condition of the brake system by examining the discs for corrosion, warping, or binding calipers, and test the brake pedal for firmness and responsiveness. For the airbag inoperability, the buyer must prioritise this issue above all others, as it is a critical safety failure that must be rectified immediately. Contact the dealer or a specialist to diagnose and repair the passenger-side airbag system, which may involve replacing the module or addressing wiring issues. The buyer should also arrange a full fluid service, including the brake fluid, coolant, and transmission fluid, as high mileage and prolonged operation without servicing can lead to degradation of these fluids, compromising the vehicle’s performance and safety. Beyond the MOT checks, inspect the tyres for signs of sidewall cracking or perishing, which can occur even with low mileage due to age-related degradation. Check the 12V battery for health, as standing vehicles can suffer from corrosion or weak terminals, and test the headlamps for proper aim and functionality, as the low aim advisories from the 2024 MOT indicate potential alignment or bulb issues. Finally, ensure the service book is up to date, as the vehicle’s age and mileage suggest it may be due for a major service, including the timing belt, if applicable, and a thorough inspection of the drivetrain and exhaust system.
