2015 Mitsubishi ASX 4 DI-D 4X4 1.8L Heavy oil · BGZ 5370

The most recent DVSA examination on 22 March 2025 resulted in a PASS with no advisories or defects recorded, indicating that at the point of testing the vehicle met the minimum roadworthiness standards required of a car of its age. The broader test history shows a generally stable maintenance trend: the Asx passed cleanly in 2019, 2020, 2022, and again in January 2024, suggesting consistent mechanical upkeep over several years. The single failure recorded in December 2024 is notable, however, and warrants further investigation. With no defect details captured in the official record it is not possible to identify the exact cause, so a prospective buyer should request the actual refusal certificate from the current owner or testing station to establish whether the failure related to a minor item that has since been rectified or a more substantial repair such as a suspension component, braking issue, or exhaust integrity matter. The recorded mileage of 119,436 miles over an 11 year vehicle life equates to an annual average of around 10,858 miles, which is broadly typical for a diesel family SUV of this vintage and suggests regular rather than exceptional use. There are, however, significant gaps in the MOT history worth noting: no test is recorded between 2020 and 2022, and again between early 2024 and late 2024, which may simply reflect successful annual tests or the vehicle being off the road, rather than anything concerning. Diesel ASX models with sustained high mileage are particularly susceptible to wear on the dual mass flywheel, clutch, turbocharger, EGR valve, and diesel particulate filter, all of which are expensive items that would not necessarily have been flagged during a standard MOT examination. Given the clean advisory record and the relatively average annual mileage, the absence of recurring flagged defects is reassuring but does not eliminate the need for a thorough physical inspection. Tyres should be examined closely for both tread depth and, importantly, sidewall perishing and cracking, as an 11 year old car is well into the territory where age-related rubber degradation becomes a concern even with adequate tread remaining. The brake discs and calipers should be inspected for corrosion and seizing from standing periods, and the handbrake mechanism on the rear drums should be checked for adjustment and operation, as binding calipers and seized rear brake mechanisms are common MOT failure points on vehicles of this profile. A test drive should include firm braking from speed to detect any shudder or pull indicating warped discs, and slow manoeuvring to listen for suspension clonks over speed humps, which would suggest worn anti-roll bar bushes, drop links, or top mounts. The 12 volt battery should be load tested, as a battery of this age is approaching the end of its reliable service life and failure can leave the vehicle stranded or cause electrical gremlins. Service history verification is essential, particularly evidence of cambelt replacement intervals being observed on the 4WD diesel powertrain, along with recent changes of engine oil, diesel fuel filter, air filter, and brake fluid, the last of which degrades on a calendar basis regardless of mileage and should ideally be renewed every two years. The diesel particulate filter should be checked for warning lights or a history of short journeys that may have caused incomplete regeneration, and the four wheel drive system should be exercised on a loose surface to confirm correct engagement of the rear axle. Finally, a thorough underbody examination on a ramp is strongly advised to identify any corrosion to the subframes, brake lines, and suspension arms, as these are areas where age related deterioration can develop without triggering an MOT failure until they reach an advanced stage.
