2015 Mitsubishi L200 2.5L Diesel · WN65 KTC

The latest MOT test on 7 October 2025 resulted in a pass, continuing a trend of annual passes since 2020, with only minor failures in 2021 and 2023 for headlamp aim and a registration plate lamp respectively. However, the recurrence of brake pipe corrosion advisories in both 2024 and 2025, now extending to the nearside, indicates a worsening condition that requires attention. While the failures were minor and quickly resolved, the persistent brake pipe advisories suggest progressive deterioration that could compromise braking integrity if left unaddressed. At 186,772 miles over eleven years, this L200 has covered an average of nearly 17,000 miles annually, which is high for its age and points to heavy usage. Such mileage accumulation typically accelerates wear on consumables like brakes, suspension components, and drivetrain parts, while also increasing the likelihood of fatigue in rubber bushes, engine mounts, and exhaust systems. The vehicle’s history of consistent use rather than prolonged standing may reduce the risk of corrosion from inactivity, but it does heighten the need for thorough inspection of high-stress components. The recurring brake pipe corrosion advisories demand immediate scrutiny. On a test drive, listen for a soft or spongy brake pedal, which could indicate air ingress or fluid loss from compromised pipes, and inspect for weeping fluid or grease-covered sections along the brake lines, particularly where they run along the chassis or near the wheels. Additionally, check for uneven braking or pulling to one side, which may signal imbalanced hydraulic pressure due to partial blockages or internal pipe degradation. Given the mileage, also examine the suspension for worn bushes or leaking shock absorbers, as these will exacerbate tyre wear and reduce handling stability. Beyond the brake pipes, the high mileage necessitates a comprehensive assessment of the drivetrain, including the clutch, propshaft, and differential for excessive play or noise, as well as the timing chain and tensioners if service records are incomplete. Inspect the tyres for uneven wear patterns, which could reveal alignment or suspension issues, and verify the age of the tyres, as sidewall cracking may still be present despite adequate tread depth. Finally, ensure all fluid levels are correct and that recent services, including timing belt or chain replacements, have been documented, as calendar-based degradation remains a concern regardless of mileage.
