2004 Land Rover Discovery 2.5L Diesel · LR03 CAM

The most recent MOT test on the 2004 Land Rover Discovery, conducted on 2025-11-17, resulted in a clean pass, indicating that the vehicle has met all current roadworthiness standards without any recorded defects. However, the advisory from the 2024-12-03 MOT—specifically noting corrosion and grease accumulation on the brake pipe from front to rear—suggests a recurring issue that has not been fully resolved. While the vehicle has passed subsequent MOTs without further defects, this advisory implies a potential long-term concern related to the brake system’s integrity. The absence of failures in the intervening years may reflect either effective remedial action or a situation where the corrosion has not yet progressed to a critical stage, but it warrants close monitoring. The overall maintenance trend appears stable, with no evidence of worsening conditions, but the brake pipe advisory should be treated as a caution rather than a passing concern. The recorded mileage of 122,844 miles for a vehicle of this age—approximately 5,584 miles per year—is unusually low, particularly given the Discovery’s robust but demanding nature. Such a low annual mileage often suggests periods of prolonged inactivity, which can exacerbate issues such as corrosion, particularly in the brake system, exhaust components, and undercarriage. Standing for extended durations can lead to brake fluid absorption of moisture, accelerating corrosion in the brake pipe and associated components, as evidenced by the 2024 advisory. Additionally, low mileage may mask wear on consumables like brake pads, suspension components, and drivetrain elements, which could have degraded over time without regular use. The vehicle’s age and the discrepancy between its mileage and typical wear patterns necessitate a thorough inspection to confirm the absence of hidden wear or corrosion, especially in areas prone to standing-related deterioration. Given the brake pipe advisory and the vehicle’s age and mileage, the prospective buyer should conduct a meticulous inspection of the brake system. Focus on the brake pipe for signs of further corrosion, particularly around joints and connections, and check for any leaks or unusual noises when braking. Listen for a grinding or squeaking sound during acceleration or deceleration, which could indicate worn brake pads or caliper binding. Inspect the brake discs for uneven wear, corrosion, or scoring, and verify that the calipers are not seized or binding. A test drive should include a slow, controlled approach to a stationary stop to assess brake performance and responsiveness, as well as any signs of pulsation or vibration, which may signal warped discs or hydraulic issues. If the brake pipe advisory remains unresolved, consider replacing the affected section with a corrosion-resistant material, and ensure the vehicle is not left standing for prolonged periods without fluid changes. Beyond the brake system, the buyer should address broader age-related checks. Given the vehicle’s low mileage, inspect the tyres for signs of sidewall perishing or cracking, which can weaken the rubber and compromise safety. Check the tread depth and ensure there are no signs of uneven wear patterns that could indicate misalignment or suspension issues. The 12V battery should be tested for charge capacity and corrosion on terminals, as standing vehicles can lead to battery drain and sulphation. Fluid levels, particularly brake fluid, coolant, and differential oil, should be checked and topped up if necessary, with a reminder that brake fluid absorbs moisture over time and should be replaced every two years or as recommended by the manufacturer. Additionally, the exhaust system should be inspected for leaks or corrosion, particularly around the catalytic converter and mufflers, as prolonged standing can accelerate rust formation. Finally, verify that the service book has been updated, as the Discovery’s maintenance schedule includes critical intervals for oil changes, suspension service, and other components that may not have been addressed due to infrequent use.
