2020 Peugeot Partner 1.5L Diesel · MM69 TWN

The most recent DVSA examination on 5 March 2026 recorded a PASS, but it was achieved only the day after a substantial FAIL on 4 March 2026, which warrants close scrutiny. That failure included a Dangerous defect for nearside rear tyre tread depth below 1.6mm, and a Major defect for a leaking fuel injector within the fuel system, both of which were apparently rectified before the retest. Advisories on the same episode flagged all three remaining tyres as being worn close to the legal limit, and the follow-up pass added advisory notes for those same tyres together with pitted or scored front brake discs and thinning front brake pads. Reviewing the trend across the recorded tests, the 2023 and 2024 examinations were clean passes, but 2023 also included a prior failure with all four tyres classed as Dangerous due to insufficient tread depth, indicating that tyre management on this vehicle has been marginal on more than one occasion. The current picture is therefore one of a vehicle that has passed its latest roadworthiness check, but only after emergency remedial work and with several advisories still pending, suggesting a maintenance profile that is deteriorating rather than stable. Recorded mileage stands at 81,999 miles over approximately six years, equating to an annual average of around 13,666 miles, which is notably high for a light commercial vehicle of this age. While this level of use suggests the vehicle has been worked consistently and is unlikely to suffer from the usual ills of prolonged standing such as seized calipers, perished cooling system hoses, or severely degraded brake discs from corrosion, it does place greater cumulative wear on the drivetrain, clutch (if applicable), suspension components, and braking system than a lower-mileage equivalent. The MOT gaps between tests do not reveal any obvious periods of inactivity, and the mileage accumulation appears steady. Mechanically, this implies that attention should focus on wear-based items rather than calendar-based degradation, although the high annual mileage combined with the advisories already noted indicates that several major service items are now approaching or past their replacement thresholds. Turning to the specific defects in the history, the recurring pattern of tyres worn on edge and close to the legal limit is a concern that requires investigation. Edge wear of this kind is most commonly attributable to misalignment, worn suspension bushes, deteriorated drop links, or weak coil springs allowing the vehicle to sit out of its designed geometry. A prospective buyer should have the tracking checked with a four-wheel aligner, and should inspect the tyres carefully for uneven inner or outer shoulder wear, as well as examine the front and rear suspension for cracked bushes, worn anti-roll bar linkages, and any sagging of the coil springs. On a test drive, listen for clonking or knocking over uneven surfaces, watch for the vehicle pulling to one side under braking or acceleration, and feel for vagueness or wandering in the steering. Given the Dangerous tread depth failures in both 2023 and 2026, it is essential to confirm that all four tyres are currently of reputable manufacture, correctly sized to the 205/60/16 specification, and have substantial remaining tread depth across the full width. The advisories concerning pitted or scored front brake discs and thinning front brake pads, combined with the Major fuel injector leak failure, also demand thorough physical inspection. The brake discs should be measured for remaining thickness against the manufacturer's minimum specification, as heavy pitting on a high-mileage vehicle typically necessitates replacement rather than skimming, and the pads should be inspected for remaining friction material and any uneven wear that might point to a binding caliper or a partially seized slider. On test, the buyer should listen for brake squeal or grinding, feel for brake shudder or vibration through the steering wheel under firm braking, and check that the vehicle pulls up straight and true. Regarding the fuel injector leak, this should be verified as fully resolved by inspecting the engine bay for any residual diesel odour, oil contamination around the injector pipes, and any signs of carbon staining or weeping at the injector seats; a failing injector can cause rough idle, excessive fuel consumption, and elevated exhaust emissions. Beyond these specific items, the relatively clean advisories from 2023 and the clean 2024 pass suggest that core mechanical components such as the clutch, gearbox, exhaust system, and structural corrosion have not been flagged, but the buyer should still satisfy themselves on a comprehensive pre-purchase inspection given the high mileage and the recent accumulation of defects, paying particular attention to fluid service histories, the condition of the cambelt if fitted to this diesel unit, and the general state of the underbody for any developing corrosion.
