2012 DAF Trucks 45 Heavy oil · DX12 APK

The defining mechanical characteristic of this 2012 DAF TRUCKS 45 is an inability to sustain a clean pass through the MOT testing station without repeat attempts. The vehicle passed on 10 September 2025, but this followed two consecutive failures just weeks earlier, on 13 August and 29 July 2025, both with no advisories or defects recorded against the test. Such back-to-back failures strongly suggest intermittent or borderline faults that do not always present on demand, typically electrical or sensor-related issues, ABS or EBS system warnings, brake imbalance readings, or emissions irregularities that may only flag under specific operating conditions such as warm-up state or load. The contrast with the prior two clean passes at June 2023 and July 2024 indicates the vehicle has entered a deteriorating compliance phase despite its established history of roadworthiness. The mileage accumulation of 241,293 miles over approximately fourteen years equates to an annual usage of around 17,235 miles, which is high for a commercial vehicle of this age. While this figure is consistent with genuine fleet or distribution work, it places significant cumulative wear on core mechanical systems including the braking components, drivetrain, suspension, and chassis hardware. The absence of any recorded annual test gaps suggests the vehicle has been in continuous commercial operation throughout its life, leaving little opportunity for prolonged component recovery or sympathetic low-mileage running. For a prospective buyer, this level of sustained use means that even unflagged wear items such as brake pads, discs, bushes, dampers, and steering linkages will likely be approaching the end of their natural service life, regardless of whether they were formally recorded. Given that the recorded defects list is empty across all tests, the primary buyer concern must centre on identifying the underlying fault that triggered the two August and July 2025 failures before the September pass. On a test drive, listen carefully for any warning lights that fail to extinguish promptly on ignition or that reappear after warm-up, particularly the ABS, EBS, or brake system warning indicators, which are common intermittent failure points on DAF LF and 45-series chassis. Request that the vendor demonstrate a live cold start and observe the dashboard cycle for any delayed warning lamp behaviour, as this is consistent with the pattern observed in the MOT history. Insist on seeing any rectification invoices for the post-July repairs, as this will reveal whether the corrective work addressed a sensor, wiring loom, or brake hydraulic component. Additionally, a vehicle at this mileage with continuous service history should be physically inspected with attention to the chassis and structural integrity, including any visible corrosion around suspension mounting points, brake pipe runs, and the rear axle area, which are typical MOT failure zones for commercial vehicles of this vintage even when not formally recorded. On road, evaluate for any pulling under braking, uneven pedal feel, or delayed response from the service brake system, as these are indicative of binding calipers or brake imbalance that can produce intermittent test failures. Listen for clonks or knocks from the front suspension over uneven surfaces, which would point to worn anti-roll bar bushes, track rod ends, or steering dampers that may be due for replacement. Given the high annual mileage and the recent failure cluster, a pre-purchase inspection by a commercial vehicle specialist with diagnostic access to the DAF electronic systems is strongly recommended to verify that the September pass represents a stable repair rather than another transient pass.
