2015 Peugeot Partner 1.6L Diesel · MV65 MZF

A recurring pattern of front-end wear is the defining mechanical theme of this Peugeot Partner's MOT record. Across four of the five recorded tests, both front brake discs have been flagged with pitting and scoring, and the issue has progressed rather than resolved: in 2021 the advisories referenced both inner and outer faces as pitted, and the most recent assessment on 23 September 2025 specifically identified the inner faces of both front discs as worn, pitted or scored. The 2025 cycle also included a failed presentation where the offside front position lamp was not working, though the same day produced a pass once the defect was rectified. More concerning are the 2024 and 2023 major failures, both involving a split constant velocity boot on the offside front outer drive shaft joint, indicating a repeat intrusion of dirt into the CV assembly that risks joint degradation. The 2024 test additionally recorded a non-functioning central front seat belt and reduced light intensity on the offside front position lamp, suggesting electrical or connector issues around the front lighting circuit. Taken together, the trajectory shows front brake discs that have been progressively deteriorating for at least four years, a CV boot that has failed twice, and lighting defects appearing in two consecutive test cycles. Annual mileage accumulation sits at roughly 11,154 miles per year over an eleven-year life, which is broadly typical for a light commercial vehicle of this age and is reflected in the steady year-on-year test cycle with no prolonged gaps in testing. There are no extended periods off the road and no sudden mileage jumps between tests, suggesting consistent operational use rather than long stationary lay-ups or sporadic heavy use. The relatively even usage pattern means consumables such as brake pads, discs, tyres, suspension bushes and CV joint components have been worked in a normal duty cycle, and the wear items now surfacing are broadly consistent with a commercial vehicle approaching the upper end of its service life. At 122,690 miles, the engine and drivetrain have covered substantial ground and oil leaks, as noted in the 2024 advisory, are a foreseeable development at this mileage. A prospective buyer should focus the physical inspection on the front brake discs, as these have been flagged repeatedly across multiple test cycles. On a test drive, listen for any grinding or pulsation through the brake pedal, particularly under firm pedal application from higher speeds, and check for a discernible lip on the outer edge of each front disc using a torch and finger run around the circumference, as a pronounced ridge suggests the discs are nearing the minimum thickness. The 2025 advisories specifically referenced the inner faces, so both sides of each disc should be examined, not just the visible outer face. Given that the offside front outer CV boot has split twice in consecutive years, the joint itself should be inspected for any signs of grease loss, clicking noises on full lock turns, or vibration through the steering, as a compromised boot left unattended will have allowed contamination into the joint and accelerated wear. The lighting defects at the 2024 and 2025 tests also warrant checking both front position lamps for consistent intensity and ensuring no flicker or intermittent failure, as this could point to a loose connector or earth issue rather than a simple bulb failure. Finally, the 2024 advisory noting an oil leak that was not classed as excessive should be monitored for progression. On inspection, look for fresh oil residue on the engine block, sump, and surrounding components, and check the undertray and garage floor for any signs of accumulation. A non-excessive leak at this mileage can originate from the cam cover gasket, sump plug, or front crankshaft seal, and while not currently a failure item, an active leak left unaddressed will worsen over time. The central front seat belt failure in 2024 is another item worth verifying directly: confirm the belt retracts smoothly, latches firmly, and the full webbing deploys without snagging, as seat belt mechanisms in commercial vehicles are subject to heavy use and the defect must be confirmed rectified.
