2018 Mitsubishi L200 2.4L Diesel · AL68 COW

Recurring corrosion on the brake pipework represents the primary mechanical concern for this vehicle, with advisories appearing in three consecutive annual inspections. The most recent test on 11 December 2025 shows the issue has progressed from the offside front brake pipe, noted in 2023 and 2024, to the nearside front brake pipe. This pattern of advisories indicates a persistent presence of corrosion on the hydraulic lines, which is currently being obscured by grease or similar substances. While the vehicle has passed its tests, the migration of this defect from one side to the other suggests a developing trend in the condition of the braking system's fluid conduits. The recorded mileage of 21,802 miles over approximately eight years indicates an unusually low usage pattern, averaging roughly 2,725 miles per year. For a commercial-oriented vehicle like the Mitsubishi L200, this level of annual accumulation is significantly below the national average. Mechanically, such low mileage reduces the wear on heavy-duty components like the drivetrain, suspension bushes, and brake discs, but it can also mean the vehicle has spent extended periods stationary. Long periods of inactivity can contribute to the development of corrosion on metal surfaces and may affect the integrity of rubber seals and hydraulic components, which aligns with the recurring brake pipe advisories. A prospective buyer should focus heavily on the condition of the braking system during a physical inspection and test drive. Given the specific advisories regarding corroded brake pipes covered in grease, it is essential to verify if the grease is being used to mask the extent of the degradation. During a test drive, pay close attention to the brake pedal feel; any sponginess, a soft pedal, or a lack of consistent pressure could indicate that the corrosion is affecting the hydraulic integrity or that air is entering the system. Additionally, listen for any unusual noises when applying the brakes and check for any pulling to one side, which might suggest uneven hydraulic pressure or binding calipers. Beyond the braking system, the low mileage and the nature of the corrosion advisories warrant a close inspection of the vehicle's underside. While no structural corrosion has been formally flagged in the MOT history, the presence of brake pipe degradation suggests that the vehicle's environment may be conducive to oxidation. Check the subframe, suspension mounting points, and exhaust system for similar signs of surface or structural rust. Because the vehicle has been driven infrequently, also inspect the tyres for flat spots or sidewall cracking and ensure that the suspension components do not produce knocks or clunks over bumps, which can occur when rubber components perish from lack of regular movement.
