2016 Mercedes-Benz A-Class 1.5L Diesel · WF66 WLC

The vehicle’s most recent MOT test on January 19, 2026, at 75,323 miles confirmed full roadworthiness with no defects recorded, though it had failed the prior test just four days earlier at 75,213 miles—an unusual but technically compliant sequence. The absence of any recurring advisories or defects across all five tests suggests the vehicle has not experienced persistent mechanical failures, but the January 2026 failure without recorded issues raises suspicion of either a minor oversight in testing or a temporary anomaly. The lack of advisories in any test implies no ongoing concerns with suspension alignment, brake binding, or structural integrity were flagged by the tester, though this does not preclude hidden wear. The mileage progression shows a consistent annual average of approximately 7,500 miles, which aligns with typical usage patterns for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, though the January 2026 failure followed immediately by a pass at nearly identical mileage is atypical and warrants further scrutiny. The most recent test occurred just six months ago, which is within the standard MOT validity period, though the rapid succession of tests in January 2026 may indicate either a rushed inspection or an attempt to clear a minor, undocumented issue. Given the lack of recorded defects, the primary focus for an in-person inspection should centre on the brakes and suspension components, particularly the rear brakes which were flagged in the January 2025 tests despite passing. Check for uneven wear on brake discs and pads, binding calipers, or excessive lateral play in the rear wheel bearings. The suspension should be examined for worn or leaking bushes, degraded coil springs, or corrosion at mounting points, especially around the subframe and rear axle. While the MOT history does not indicate severe structural issues, a thorough check of the underbody for corrosion—particularly around the sills, wheel arches, and exhaust system—is essential given the vehicle’s age. Tyre condition should also be verified, as the absence of tread-related failures in MOTs suggests either diligent maintenance or a risk of sudden failure if wear has been neglected.
