2006 Mitsubishi Shogun 3.2L Diesel · WM06 OAW

This 2006 Mitsubishi Shogun presents a roadworthiness profile dominated by chronic minor defects and a single but serious dangerous failure, painting a picture of an ageing vehicle where cosmetic and electrical ancillaries have been neglected even while major mechanical items have generally remained within test limits. The most recent test on 14 March 2024 was a pass, but it carried forward the now familiar trio of loose offside and nearside obligatory mirrors and an insecure battery carrier that have appeared virtually every year since 2021. The defining episode in the record is the 8 March 2023 failure, where the front brake imbalance across an axle was recorded as dangerous, exceeding the fifty per cent threshold. This is a substantial safety finding that suggests uneven pad wear, a binding caliper, a seized slider, or a hydraulic distribution issue, and while the vehicle subsequently passed one week later, no advisory was raised to confirm the rectification was inspected in detail. The combination of that dangerous brake finding, a fractured rear coil spring the year prior, and a leaking cooling system flagged repeatedly since 2022 indicates that the underlying structural and braking components are now at an age where failures and advisories are accumulating rather than being resolved. With 154,744 miles recorded on a vehicle of approximately twenty years of age, the usage profile equates to around 7,700 miles per year, which is broadly typical for a working-class off-roader of this era. The MOT testing history shows annual tests from 2019 onwards with no multi-year gaps, suggesting the Shogun has been in continuous use rather than laid up for extended periods, which removes concerns about dried seals, seized brakes, and perished fuel lines that often accompany long-term storage. However, this consistent usage at moderate annual mileage means the higher-mileage wear items, particularly the rear coil spring that fractured in 2022, the corroded fuel pipes flagged in 2023 and 2024, and the suspension ball joint showing play in 2021, are still very much live concerns. The annual mileage is not low enough to discount mechanical wear, but it is consistent with the advisories seen. For a prospective buyer, the brake system must be the primary inspection focus given the dangerous imbalance recorded in March 2023. On a test drive, the vehicle should be assessed for pulling to one side under moderate braking, any pulsing or judder through the pedal which would suggest disc warping, and whether the handbrake requires excessive travel, as the parking brake lever was flagged for excessive movement in the same failure. Listen for any grinding or scraping from the front calipers when cold, and check that both front discs reach a similar temperature after a short drive. Inspect the visible brake pipes and fuel lines along the chassis and undercarriage for surface corrosion and any signs of repair tape or sealing compound, particularly the nearside front pipe which was greased over in 2023, and the corroded fuel pipes recorded in 2024. The fractured rear coil spring on the nearside in 2022 is a known weak point on this model generation, so the vehicle should be rocked laterally to detect any clonking from the rear, and the ride height should be checked for obvious sagging on one side. The cooling system deserves equally close attention, as a coolant leak has been flagged at every test since 2022, originally offside rear and now generalised. On inspection, allow the engine to reach full operating temperature and observe the radiator, expansion tank, and hose joints for seepage, particularly around the rear of the engine bay. The 2022 advisory noting the vehicle has reached an age where all components are corroded should be taken at face value, meaning a thorough examination of the subframe, suspension mounting points, brake line junctions, and exhaust hangers is essential, ideally with the vehicle on a lift. Check the offside front upper suspension arm ball joint for play, as the 2021 advisory has had three years to develop into a worn joint, which would manifest as imprecise steering and a clunk over speed humps. Finally, the headlamp lenses, windscreen wiper blades, and battery mounting hardware have been minor failures across multiple tests, and while individually trivial they collectively indicate deferred maintenance that often masks more significant underlying issues on a vehicle of this age and mileage.
