2004 Land Rover Discovery 2.7L Diesel · CP54 AJX

The 2004 Land Rover Discovery presents a mixed roadworthiness picture marked by recurring suspension concerns, intermittent braking difficulties, and structural deterioration alongside occasional clean passes. The most recent test on 2025-03-07 resulted in a pass despite persistent advisory flags, yet the overall pattern reveals a vehicle that has experienced multiple failures across different systems rather than a single isolated issue. Between the two failed tests in late 2025 and early 2024, the car accumulated nearly 60,000 miles while maintaining a pace of approximately seven thousand miles per year, which aligns with expected depreciation but masks underlying reliability challenges. The latest successful assessment does not erase the earlier critical failures, and the continued presence of advisory items suggests the vehicle remains operating under conditions that could compromise safety if not addressed promptly. The mileage figure of 155,649 miles on a twenty-two-year-old chassis translates to roughly seven thousand seven hundred miles annually, a rate that appears typical for its age though the distribution of wear is uneven. Gaps between tests reveal periods where the vehicle sat idle or was driven minimally before subsequent failures emerged, notably the jump in reported issues beginning in late 2023 when the anti-roll bar bush wore excessively and rear sill panels developed noticeable corrosion. The 2023 failure included both structural damage to the rear subframe and hydraulic system problems, while earlier failures involved suspension articulation and braking performance. This usage profile indicates that while daily driving volume was moderate, the vehicle endured significant stress events—particularly around the suspension geometry and braking system—that manifested as multiple failed assessments within a six-month window. Buyers should treat the nearside front and rear lower suspension arm ball joints as primary red zones given their repeated appearance across all MOT records as either slightly played or worn. During a test drive, expect to hear knocks or clunks over bumps if the ball joints retain play, and watch for pulling to one side or hesitation at corners if the upper suspension arms exhibit worn pins or bushes. The nearside front service brake showing binding on the 2025-03-05 failure warrants particular attention; during operation you should note whether the brake pedal feels spongy, resistant, or if the vehicle pulls to one corner when applying the front service brake. Lighting failures are also widespread, so verify that all exterior position indicators function before purchase, and inspect the offside stop lamps and windscreen washer reservoir as they indicate separate electrical or pump-related deficiencies. Finally, the documented rear sill panel corrosion represents a structural concern that could affect rigidity and safety under load, and the oil leak noted on two occasions should be checked for source location and potential contamination of the cooling system or transmission fluid.
