2004 Land Rover Discovery 2.5L Diesel · OF04 OAD

The most recent DVSA examination on 11 June 2022 resulted in a pass with no advisories or defects recorded, which is the strongest outcome in the available history and confirms the vehicle met all statutory roadworthiness requirements at that time. Looking at the broader trajectory, the vehicle has passed every annual test consecutively since at least 2015, with no failures recorded, and the 2022 clean result follows a 2021 pass that was similarly free of recorded observations. While advisory items did appear intermittently in earlier tests, none have escalated into categorised failures, indicating that remedial work has been carried out as required and the overall maintenance trend can be regarded as stable and conscientiously managed rather than worsening. With a recorded odometer reading of 90,831 miles spread across approximately 22 years of service, this Discovery has averaged only around 4,129 miles annually, which is well below the typical mileage expected for a vehicle of this vintage. Such low annual usage strongly suggests periods of standing or only light, irregular use, and while it preserves the engine, transmission and drivetrain from high wear, it brings specific concerns associated with inactivity. Corrosion can develop on brake discs due to surface rust accumulation, particularly on the rear axle of a Land Rover, and flexible components such as hoses, gaiters, seals and suspension bushes are prone to perishing and cracking when not regularly exercised. The growing mileage gap between the 2022 test and the current date of September 2026 means there is also a four-year period without recorded MOT history, during which the statutory annual test would have been required and should be verified directly with the seller. Given the clean MOT history and the very low annual mileage, physical inspection becomes especially important. The buyer should scrutinise all four tyres for sidewall perishing and cracking typical of age rather than wear, as tyres older than six years from their DOT date stamp should be replaced regardless of remaining tread depth. The 12V battery is highly likely to require replacement or thorough load testing, given that prolonged standing periods severely degrade battery capacity and Land Rover electrical systems are particularly sensitive to voltage drop. Brake discs, especially on the rear, should be inspected for advanced surface corrosion, and the caliper slides and handbrake mechanism should be checked for binding, seizing or uneven pad wear that commonly develops on vehicles that have stood idle. Brake fluid should be considered due for replacement on calendar age alone, as the fluid degrades hygroscopically over time regardless of mileage, and the same applies to coolant, which on a 2004 Discovery should have been renewed multiple times. Coolant hoses, the radiator, the heater matrix and the cylinder head gasket area should be visually inspected for any signs of leakage or staining, as the TD5 and later V8 engines in this generation are known for age-related sealing issues. A thorough underside inspection on a ramp is strongly recommended to confirm the structural condition of the chassis and outriggers, as corrosion in these areas is a known concern for the Discovery 3 platform. On the road, particular attention should be paid to the suspension, as the 2020 MOT recorded deteriorated ball joint dust covers on both front lower arms, and while these were classed as minor at the time, perished gaiters permit water and grit ingress that accelerates joint wear. Any clonks, knocks or imprecise steering response over uneven surfaces would warrant immediate investigation. The 2017 advisory concerning a slight play in the offside front track rod end ball joint indicates the steering linkage has been subject to wear, and uneven or feathered tyre wear on the front wheels would suggest this has progressed. Additionally, the 2017 advisory noting corrosion on the rear brake pipes should prompt a close examination of the underbody brake lines and unions for advanced rust, as brake pipe failure is a categorised failure item and an obvious safety concern. A careful test drive should be conducted to listen for any drivetrain shunt, transmission hesitation or transfer box vibration, given that low-mileage Land Rover vehicles can develop sealed-component issues if not regularly exercised, and a thorough warm-up period is essential to confirm stable idle and coolant temperature behaviour before any purchase commitment.
