2004 Volvo FM12 12.1L Diesel · DX04 DNU

The vehicle maintains a roadworthy status, though the maintenance trend shows a shift toward developing fluid leaks and mechanical wear. The most recent test in May 2026 at 54,869 miles identified a damp power steering box and a hydraulic oil leak near the nearside. These issues represent a regression from the clean record seen in March 2024, suggesting that the vehicle's seals and auxiliary steering components are beginning to fail due to age despite the low operational hours. The mileage profile is highly irregular for a 22-year-old vehicle, averaging approximately 2,500 miles per year. There is a significant discrepancy in the recorded data between November 2021 and December 2022, where the mileage jumped from 622,738 to over 1,012,000 miles. This million-mile entry suggests either a clerical error or an odometer replacement rather than actual usage. Since that jump, the vehicle has covered less than 60,000 miles, indicating intermittent use or long periods of standing which often leads to the degradation of rubber components and the stagnation of fluids. A physical inspection must focus on the recurring hydraulic and steering issues flagged in the recent tests. The damp power steering box and nearside oil leak require a pressure test to ensure they are not precursors to catastrophic failure. Furthermore, the slight movement in the axle 3 king pins noted in March 2025 necessitates a thorough check of the rear suspension assembly to ensure the bushings or pins are not excessively worn. Given the low mileage and age, the buyer should also inspect for dry rot in the tyres and perished brake lines, which frequently affect vehicles that remain stationary for extended periods.
