2004 Scania 164 15.6L Diesel · XHZ 144

The vehicle presents a clean and stable MOT history, with the most recent test conducted on 2 April 2026 returning a pass with no defects or advisories recorded. This clean result is consistent with the four prior annual tests dating back to February 2022, all of which were likewise passed without any noted advisories, advisories, or failure points. The absence of recurring defect patterns across five consecutive MOT examinations suggests that the vehicle has been subject to diligent maintenance or that it has not been exposed to conditions that typically generate advisories, such as prolonged standing, heavy commercial use, or neglect of consumable items. For a prospective buyer, this consistent pass history is a positive indicator of overall roadworthiness, although it is important to recognise that the MOT test is a non-invasive annual check rather than a comprehensive mechanical inspection, and does not cover engine internals, gearbox condition, or turbocharger health. Regarding recorded mileage, the vehicle shows 331,731 miles over approximately 22 years of service, which equates to an annual accumulation of around 15,079 miles. For a heavy commercial vehicle of this age and type, this represents very high utilisation and is consistent with a working truck that has been in continuous service rather than one that has stood idle for extended periods. There are no significant gaps in the mileage progression across the recorded MOT tests, indicating the vehicle has remained in regular use throughout the documented period. Such high annual mileage has direct mechanical implications, with the engine, drivetrain, braking system, suspension, and tyres all subject to accelerated wear relative to a lower-mileage equivalent. Components such as clutch assemblies, turbochargers, injectors, and major drivetrain bearings will have endured considerable stress, and any prospective buyer should account for the likelihood of significant upcoming maintenance expenditure. Given the absence of any recorded advisories or defects in the MOT history, there is no specific component flagged for imminent attention. However, the combination of high mileage and the vehicle's age necessitates a thorough physical inspection prior to purchase. Particular attention should be paid to the condition of the braking system, including disc wear and any signs of binding calipers that may not yet have manifested as an MOT failure. The suspension should be examined for worn bushes, perished shock absorbers, and any signs of cracked or sagging coil springs, all of which are common on high-mileage commercial vehicles. On a test drive, listen for any clonks or rattles from the suspension over uneven surfaces, and observe whether the vehicle pulls to one side under braking, which may indicate warped discs or uneven pad wear. Exhaust smoke, excessive play in steering components, and any unusual transmission behaviour under load should also be carefully assessed. In addition to mechanical wear considerations, age-related degradation should form part of any inspection. Tyre sidewalls should be checked for perishing or cracking, as rubber compounds deteriorate with calendar age regardless of tread depth, and the condition of the braking hydraulic system and fuel lines should be examined for any signs of corrosion or leakage. The 12-volt battery should be tested for its state of charge and cranking performance, particularly given the demands placed upon it by commercial vehicle electrical systems. Coolant, brake fluid, power steering fluid, and engine oil should all be inspected for age and condition, with reference to the service history to confirm that time-based fluid changes have been carried out in accordance with manufacturer schedules. Finally, given the working nature of the vehicle, a compression test and a thorough inspection of the engine, gearbox, and rear axle for oil leaks would be prudent, alongside verification of the service book stamps and any available maintenance records to substantiate the mileage and confirm that major service intervals have been observed throughout the vehicle's life.
