2021 Scania Unknown 12.7L Heavy oil · PN70 AAJ

The most recent DVSA MOT test dated 20 February 2026 resulted in a PASS with no defects or advisories recorded, indicating that the vehicle satisfied all statutory roadworthiness requirements at that examination. However, the immediate prior test on 31 January 2026 was a FAIL despite also showing no defects recorded, which likely reflects an administrative refusal or rejection of the initial presentation rather than a documented mechanical issue. Looking at the broader pattern, the 2024 test passed cleanly, but the 2025 cycle showed a major brake-related failure on 10 January followed by a pass later the same day, suggesting an on-the-spot rectification was made before retest. The overall trend is broadly stable with isolated brake concerns rather than a pattern of deteriorating mechanical condition, though any prospective buyer should not overlook the brake defect given its safety-critical nature. This 2021 SCANIA has accumulated 411,928 miles over approximately five years, equating to an average annual mileage of around 82,386 miles. This is an exceptionally high usage rate for a vehicle of its age and points to intensive commercial operation, most likely long-haul trunking or high-utilisation fleet duty. Such sustained high mileage places considerable cumulative wear on the drivetrain, turbocharger, clutch, suspension components, and braking system, as well as accelerating fatigue in items such as wheel bearings, propshaft universal joints, and steering linkages. There are no significant gaps in the recorded MOT history that would suggest prolonged periods of standing, which removes the typical concerns around seized calipers, brake disc corrosion, or perished coolant hoses, but conversely means every consumable on the vehicle has been worked hard throughout its life. Given the recorded brake roller test failure from January 2025, a thorough inspection of the braking system is essential prior to purchase. The defect relating to imbalanced braking effort between wheels on the same axle typically points to uneven brake actuation, which can stem from a seized or sticking caliper, a worn or seized brake mechanism, contaminated friction material, a faulty load-sensing valve, or air ingress in the pneumatic or hydraulic circuit. On a test drive, the buyer should listen for any chirping or grinding from the wheel area, feel for the vehicle pulling noticeably to one side under heavy braking, monitor for delayed brake response, and check for any warning indicators on the dashboard. A rolling brake tester measurement at an HGV specialist would be the most reliable way to confirm whether the imbalance has been fully resolved or whether residual issues remain. Beyond the brake system, the exceptionally high mileage warrants close scrutiny of several age-related and wear-sensitive items. Tyres should be examined not only for tread depth but for uneven shoulder wear indicative of alignment or suspension component wear, as well as any sidewall cracking or perishing given the vehicle's age. The exhaust system, including the diesel particulate filter, should be checked for warning lights or stored DTCs that might indicate DPF regeneration issues, and the AdBlue system verified for correct operation. Engine oil, coolant, transmission fluid, and any hydraulic fluid reservoirs should be inspected for condition and service intervals verified against the manufacturer's schedule, since calendar-based fluid degradation still occurs even on high-mileage vehicles. A compression test, injector balance check, and turbocharger boost verification would be prudent given the working environment, and a full underbody examination for corrosion, oil leaks from the rear main seal or sump, and structural integrity around suspension mounting points is strongly recommended before committing to purchase.
