2011 Mitsubishi L200 2.5L Diesel · SC59 DAN

A clear pattern of structural and underbody corrosion is developing on this 2011 Mitsubishi L200, and any prospective buyer should treat it as the defining mechanical concern rather than a passing formality. The most recent test on 8 December 2023 recorded three advisories, two of which point directly to corrosion-related deterioration: a minor exhaust gas leak at the rear and, more tellingly, vehicle structure corroded without yet compromising rigidity. One week earlier, on 1 December 2022, the vehicle failed outright on excessively corroded brake pipes on three separate sections, including the front-to-rear run and both front brake pipes, alongside non-functional horns and an incompatible headlamp light source. It then passed a retest eight days later with no defects recorded, indicating the brake lines were repaired or replaced. The combination of an advisories list that is now beginning to accumulate structural observations on top of a recent pipe-corrosion failure suggests corrosion is active and likely to be the limiting factor in the vehicle's long-term roadworthiness, particularly as a working utility vehicle that may have seen rural or off-road use. The mileage profile is unusually low for a fifteen-year-old commercial pickup, with 83,936 recorded miles equating to roughly 5,596 miles annually. This is well below the typical accumulation rate for an L200 of this vintage, which often sees significantly higher annual mileage given its working vehicle remit. Lower mileage on a pickup of this age can mean lighter mechanical wear on the engine, clutch and drivetrain, but it can equally indicate long periods of standing, which itself accelerates corrosion through moisture retention, particularly on underbody components, brake lines and exhaust fittings. The absence of any test entry between December 2021 and December 2022, and again between December 2022 and December 2023, suggests the vehicle has not been tested every year, which on a vehicle of this age is consistent with either SORN periods or simply irregular use, both of which are risk factors for the type of brake pipe and structural corrosion already being recorded. Inspection priorities for this L200 should centre on the underbody and braking system, as the MOT history shows these are the areas where the vehicle is already presenting problems. On a physical inspection, the brake lines running front-to-rear and the front brake pipe unions should be examined closely for surface rust, flaking, pitting and any evidence of recent replacement or repair, as the December 2022 failure indicates this was an active area of concern. The exhaust system should be inspected for the source of the recorded rear leak, paying particular attention to joint condition and any blueing or soot staining that suggests an active blow. The advisory concerning structural corrosion warrants a thorough check of the chassis rails, outriggers, crossmembers, suspension mounting points and any factory seams, looking for bubbling paint, flaking surface rust or any areas where a magnet does not hold firmly, which would indicate more advanced perforation than the tester noted. On a test drive, listen for any metallic whine or hum from the wheel bearings, particularly when changing direction, as the rear bearing was flagged as slightly noisy at the last test and is likely to have progressed. Brake pedal feel should be firm and consistent, with no sponginess or excessive travel that might indicate further corrosion has affected flexible lines or the master cylinder, and there should be no pulling to either side under braking which could indicate a binding caliper. The headlamp light source compatibility issue from 2022 should be confirmed resolved with the correct rated bulbs fitted, and the horn should be checked at the wheel. Listen over uneven surfaces for clonks or rattles from the front suspension, particularly from the anti-roll bar links and bushes, and check for any steering vagueness or wandering that could indicate worn components exacerbated by the vehicle's age. Given the active corrosion pattern, a pre-purchase inspection on a ramp is strongly advisable before committing to this vehicle.
