2021 Scania S500 12.7L Diesel · SS04 MCB

The Scania S500 presents a remarkably clean MOT record, with the most recent test conducted on 14 May 2026 at 601,981 miles resulting in a pass and zero defects. This outcome, combined with four consecutive clean passes dating back to May 2022, indicates a stable and well-maintained vehicle. No recurring faults, advisories, or failures appear across the entire recorded history, which is exceptional for a heavy goods vehicle of this age and mileage. The mileage accumulation tells a clear story of intensive commercial use. From 119,252 miles at the first recorded test on 10 May 2022 to 601,981 miles by May 2026, this truck has covered approximately 482,729 miles in four years, averaging over 120,000 miles annually. The intervals between tests show consistent high utilisation: roughly 118,000 miles between May 2022 and May 2023, about 118,000 between 2023 and 2024, and approximately 111,000 between 2024 and 2025. The final interval from April 2025 to May 2026 accounts for around 136,000 miles, suggesting the vehicle may have been worked harder in its most recent period or that the 2025 test occurred earlier in the year than the typical May cycle. Despite the defect-free paperwork, a buyer should not treat the clean MOT history as a substitute for physical inspection. At over 600,000 miles, critical drivetrain components including the clutch, gearbox, and drivetrain mounts will have endured enormous cyclic loading. The chassis rails, cross-members, and suspension mounting points deserve close scrutiny for fatigue cracking or corrosion, particularly around the fifth-wheel area and rear suspension hangers. Brake actuators, air lines, and the compressor should be examined for wear consistent with heavy commercial operation. Tyre condition and wheel bearing play are worth verifying firsthand, as these consumables can deteriorate rapidly between tests on a vehicle covering this sort of annual distance. The clean record suggests attentive ownership, but the sheer volume of work this truck has done means a thorough in-person assessment remains essential.
