2012 Alexander Dennis Unknown 4.5L Diesel · D6 LTS

The most recent MOT test on 2026-02-05 confirms this Alexander Dennis vehicle remains roadworthy at 548,777 miles, with no defects recorded. The passing trend over the last two tests—both in February 2025 and February 2026—suggests no recurring mechanical failures, though the absence of advisories or defects does not preclude underlying wear. The 548,777-mile mark is unusually high for a 14-year-old vehicle, particularly given the 8,602 miles accumulated between tests, which is consistent with heavy usage. Without any advisories or defects in either test, there is no evidence of deferred maintenance or recurring issues, though the lack of inspection history beyond these two points leaves critical components unassessed. The recorded mileage of 548,777 miles over approximately 14 years equates to an average of 39,198 miles annually, which is significantly higher than typical usage patterns for commercial or passenger vehicles of this age. The most recent test in February 2026, just five months ago, means the vehicle has not yet reached its next MOT due date. This suggests either regular compliance with testing intervals or a deliberate delay in scheduling. The gap between tests—540,175 to 548,777 miles—indicates steady usage without extended periods of inactivity, which could imply consistent operation rather than neglect. Given the lack of recorded defects or advisories, a buyer should prioritise an independent inspection of high-wear components such as suspension bushes, coil springs, and brake calipers, as these are often the first to fail under heavy mileage. The absence of MOT advisories does not rule out corrosion in wheel arches, subframes, or body panels, particularly in exposed areas where salt or moisture could accelerate deterioration. Additionally, the braking system—though not flagged—should be thoroughly checked for uneven wear on discs or pads, as binding calipers or warped rotors are common in high-mileage vehicles. The drivetrain and exhaust system, while not mentioned in the MOT, warrant scrutiny for leaks, unusual noises, or excessive emissions, especially given the vehicle’s age and mileage.
