2004 Land Rover Discovery 2.5L Diesel · BF04 BXM

The 2004 Land Rover Discovery has a consistent pattern of recurring oil leaks and corrosion-related issues, with no significant improvements in recent MOTs. The most recent 2023 MOT noted front and rear suspension components corroded, alongside oil leaks from the engine and gearbox, which were also recorded in earlier tests. These issues suggest ongoing problems with seals, gaskets, or undersealing, which may indicate poor maintenance or exposure to harsh conditions. Corrosion on suspension parts and underbody components has been documented since at least 2019, with undersealing and plating applied in 2022 and 2023. While these treatments may have mitigated some rust, the persistence of corrosion and oil leaks implies that the vehicle’s underbody remains vulnerable to further degradation. Brake disc wear has also been a recurring concern, with pitting and scoring noted in multiple tests, though not to a critical extent. The condition trend appears stable rather than worsening, as no new or more severe defects have emerged in the latest MOT. However, the lack of improvement in oil leaks and corrosion over seven years raises concerns about long-term reliability. The vehicle’s mileage of 180,012 miles (roughly 8,182 miles per year) is typical for its age, suggesting average usage rather than heavy wear or prolonged inactivity. This mileage does not strongly indicate excessive stress on components, but it also does not rule out gradual deterioration.
