2018 Mercedes-Benz A-Class 1.5L Diesel · LM68 AAE

The most recent DVSA MOT test for the 2018 Mercedes-Benz A-Class was conducted on 2026-09-01, which has not yet been recorded in the provided history, suggesting this assessment is based solely on the available past tests. The vehicle’s MOT history reveals a concerning pattern: it failed in 2021-10-26 due to a dangerous failure of the near-side front tyre, where ply or cords were exposed—a severe condition that compromises tyre integrity and road safety. This failure was not repeated in the subsequent MOTs, with the 2021-10-28 test passing and the 2022-10-31 test recording only an advisory for a near-side front tyre nail, indicating a likely response to the prior failure. While the vehicle has since passed subsequent tests, the exposed tyre cords from 2021 remain a critical red flag, implying either a lack of proper tyre maintenance or underlying wear issues that may have been overlooked. The absence of further failures suggests either corrective action was taken or the issue was resolved, but the history does not provide clarity on whether the tyre was replaced or if the vehicle was otherwise adjusted to mitigate further risk. The recorded mileage of 116,307 miles for an eight-year-old A-Class represents a high annual usage rate of approximately 14,538 miles per year, which is notably elevated for a vehicle of this age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluid degradation over time. The lack of significant mileage gaps—particularly if the vehicle was driven continuously without prolonged periods of inactivity—could exacerbate issues such as corrosion from standing fluids, binding suspension parts, or premature tyre wear patterns. For instance, standing in one position for long periods can lead to brake disc corrosion or caliper binding, while high mileage may accelerate suspension bush wear, resulting in clunking noises or uneven ride quality. Additionally, the high mileage suggests a greater likelihood of fluid degradation, such as brake fluid absorption of moisture or engine oil dilution in the automatic transmission fluid, both of which can compromise system performance and longevity. Given the vehicle’s MOT history, the buyer should prioritise a thorough inspection of the near-side front tyre, as the exposed cords from 2021 indicate a critical failure that must be addressed. On a test drive, listen for unusual noises from the front suspension, particularly clunking or rattling, which may signal worn or damaged suspension bushes, coil springs, or lower arm components. Inspect the front wheels for uneven tyre wear, which could point to misalignment, camber issues, or suspension misalignment. Additionally, check for any fluid leaks under the vehicle, particularly around the front wheels, as this may indicate brake system or wheel bearing problems. The exposed tyre cords suggest the vehicle should have had the tyre replaced immediately after the 2021 failure, so the buyer should verify whether this was done and confirm the tyre’s tread depth is legal and adequate for safe operation. If the tyre was not replaced, the risk of a repeat failure or sudden blowout remains high, making this a non-negotiable issue. Beyond the tyre, the buyer should also assess the vehicle’s brake system for signs of wear or corrosion, especially the near-side front discs and calipers, as prolonged standing or high-mileage usage can lead to rust buildup or binding. Inspect the brake discs for uneven wear, grooving, or corrosion, and listen for grinding noises when applying the brakes, which could indicate worn brake pads or metal-to-metal contact. The suspension should be checked for any play or binding in the front suspension components, as well as the alignment of the steering system, which can be affected by high mileage or previous repairs. Given the vehicle’s age and mileage, it is advisable to verify the service history for fluid changes, particularly the brake fluid, engine oil, and automatic transmission fluid, as these fluids degrade over time and should be replaced at specified intervals. Lastly, the buyer should conduct a visual inspection of the vehicle’s exterior for signs of rust or structural damage, particularly around the wheel arches and undercarriage, as high mileage can accelerate corrosion in these areas. If the vehicle has been driven at a high rate of miles per year, it is also prudent to check the 12V battery for signs of weakness or failure, as prolonged use can drain the system and lead to electrical issues.
