2021 Scania R450 12.7L Diesel · PJ71 NFN

The vehicle remains roadworthy, though the maintenance trend shows early signs of degradation after several years of clean records. The most recent test on 10 December 2025 at 562,837 miles introduced the first advisories in the history. The tester flagged a spray suppression system beginning to clog and identified an oil leak from the sump. While these did not result in a failure at the time, they indicate that the vehicle is entering a phase where component wear requires proactive attention given the high operational intensity. The mileage pattern reflects a consistent and heavy-duty commercial application, averaging over 112,000 miles per year. Between December 2022 and December 2023, the truck covered 140,465 miles, followed by another 108,055 miles in the subsequent year. This rapid accumulation of mileage suggests the vehicle has been used for long-distance haulage rather than local distribution, which places significant stress on the drivetrain, suspension, and braking systems compared to a typical five-year-old vehicle with lower mileage. A buyer must conduct a thorough physical inspection of the engine sump area to determine the severity of the oil leak noted in the 2025 test. Given the high mileage, checking for weeping around the engine seals and turbocharger is essential to prevent catastrophic failure. The focus should also shift to the suspension bushings and air system components, as the high annual mileage accelerates the fatigue of rubber and metal. The spray suppression system should be monitored or cleaned soon to ensure it does not lead to a failure in the next MOT cycle.
