2004 Land Rover Discovery 2.5L Diesel · AF04 XWN

The most recent MOT test on the 2004 Land Rover Discovery occurred on 2025-11-07 and resulted in a pass, though it included two persistent advisories: slight play in the rear anti-roll bar linkage ball joint and minor but noticeable oil leaks from the front and central sumps. While the 2020 test showed a major failure for excessive play in the near-side drag link end ball joint, this was not repeated in subsequent years, suggesting that the vehicle’s suspension components have either been addressed or that the issue resolved itself through routine maintenance or natural wear progression. The earlier 2020 advisory regarding offside front inner vehicle structure corrosion—despite not compromising structural rigidity—indicates ongoing exposure to moisture or poor storage conditions, which may have contributed to the 2020 failure. Overall, the maintenance trend appears stable, with no repeated major defects beyond the one isolated incident in 2020, though the recurring advisories on ball joints and oil leaks warrant continued vigilance. The vehicle’s recorded mileage of 140,669 miles over approximately 22 years represents a moderate annual usage rate of around 6,394 miles per annum, which is within the expected range for a vehicle of this age and class. This usage profile suggests a mix of operational and potentially stationary periods, which could explain the lower-than-expected mileage compared to some peers. The suspension and drivetrain components, particularly ball joints and linkages, are subjected to wear from both dynamic loading and static stress when the vehicle stands idle, especially in harsh environments or poor conditions. The presence of oil leaks—particularly from the front and central sumps—may indicate worn seals or gaskets, which can accelerate wear on adjacent components like the transmission or engine mounts if left unaddressed. Additionally, the corrosion advisories on the vehicle structure, especially noted in 2020, suggest prolonged exposure to damp conditions, which could exacerbate long-term issues if not mitigated. For a prospective buyer, the most critical areas to inspect are the suspension and drivetrain components, given the recurring advisories on ball joints and oil leaks. During a test drive, listen for unusual noises such as clunks or rattles from the rear anti-roll bar linkage or drag link, which may indicate further play or component failure. Check for uneven tyre wear patterns, which could signal misalignment or suspension issues, and inspect the tyres for signs of excessive dry rot or sidewall cracking, particularly given the vehicle’s age. The oil leaks should be visually confirmed by looking for dark streaks or dampness around the sumps, and the leaks themselves should be traced to their source—potential candidates include the front suspension mounts, transmission fluid reservoir, or engine oil pan. If the leaks are confirmed as minor, they may not immediately pose a roadworthiness risk but should be monitored closely, as they could escalate into more serious mechanical failures. In addition to the mechanical checks, the buyer should conduct a thorough inspection of the vehicle’s structural integrity, focusing on the offside front wing area where corrosion was previously noted. Look for signs of rust penetration, particularly around riveted or bolted joints, and check for any soft spots or bulges that could indicate underlying structural compromise. The battery should be tested for charge capacity and terminal corrosion, especially given the vehicle’s age and potential for prolonged periods of disuse. Fluid levels should be checked—particularly the engine oil, brake fluid, and coolant—and their condition assessed for degradation or contamination. If the vehicle has been stored for extended periods, the brake discs should be inspected for corrosion or binding, which can occur when the wheels are stationary for long durations. Finally, verify the service history for any missing or outdated maintenance records, such as suspension component replacements or fluid servicing, to ensure the vehicle has been properly maintained despite the advisories.
