2017 Renault Koleos 2.0L Diesel · BD67 XSR

A clear and persistent theme of tyre deterioration is the defining mechanical story of the recorded MOT history for this Renault Koleos. Across three consecutive tests, perishing has been flagged on every corner of the vehicle: both front tyres were noted as starting to perish in May 2025, and by the most recent pass on 15 June 2026, the issue had migrated to both rear tyres, which were recorded as slightly damaged, cracking or perishing. Rubber degradation of this consistency on a vehicle of relatively low annual mileage is a significant indicator that age — rather than mileage wear — is the primary enemy of the tyres. Underneath the tyre story, the underlying brakes and chassis have remained entirely free of advisory comments at the most recent test, and all six recorded examinations have resulted in a pass with no failures, which reflects a stable roadworthiness trajectory over the documented period. The mileage profile of this Koleos is notably unusual for a nine-year-old vehicle, with only 13,758 miles recorded — an average of roughly 1,529 miles per year over its lifetime. Testing began in November 2020 and then continued annually without interruption, suggesting the vehicle has remained in regular use rather than being laid up for extended periods. However, the very low annual mileage does warrant mechanical consideration. Components that suffer from prolonged standing rather than active wear — such as brake discs corroding on their faces, seized handbrake mechanisms, deteriorated rubber boots and bushes, and a 12V battery losing cranking capacity — are more pertinent concerns than high-mileage items like engine internals or clutch friction material. The absence of any advisories relating to seized brakes or rusted components on the recent test is reassuring, but a buyer should remain alert to the specific failure modes associated with low-use vehicles. The brake system has attracted a handful of advisories over the history, all clustered around the offside axle. In May 2022, the offside rear brake pads were recorded as wearing thin, and in May 2023, both the offside front and offside rear brake discs were flagged as worn, pitted or scored but not seriously weakened. These items have not reappeared on subsequent tests, suggesting they have since been addressed, though it is worth confirming directly with the seller what work was carried out and whether replacement discs or pads were fitted. On a test drive, listen for any grinding or scraping from the offside wheels, particularly at low speed, and pay attention to any vibration or shudder through the brake pedal under firm application — both symptoms that could indicate the discs have worn unevenly or that pad material has transferred to the disc surface. Tyre condition must be the priority inspection point for any prospective buyer of this vehicle. Given that every set of tyres fitted over the last three years has shown signs of perishing, the current rubber is almost certainly aged and should be thoroughly examined for sidewall cracking, particularly in the flexing zones near the tread shoulder and the bead area. Even tyres with adequate tread depth can be unsafe if the compound has hardened and the structure has begun to fail. Beyond the tyres, attention should turn to the consequences of low annual mileage: check that the handbrake holds firmly on an incline without creeping, listen for any clonking or squeaking from the suspension over speed humps which would suggest seized bushes or corroded brake pad slides, and verify that the engine starts promptly without extended cranking, as the 12V battery may have weakened from infrequent use. A steady test drive with no warning lights illuminated and a smooth idle would support the otherwise clean mechanical picture presented by the MOT record.
