2009 Renault Koleos 2.0L Diesel · BF09 KOW

The Renault Koleos in question presents a mixed but ultimately concerning maintenance history, with the most recent MOT—conducted on 24 June 2025 at 143,267 miles —resulting in a failure with no recorded defects . This is unusual, as a failed test typically requires at least one advisory or dangerous defect to be noted. The prior MOT, just 12 months earlier on 25 May 2024 at 139,934 miles , passed without issues, suggesting the failure may have been administrative rather than mechanical. However, the double entry on 6 June 2022 —both a pass and a fail at 124,168 miles —indicates either a clerical error or an unresolved issue that wasn’t properly addressed. The absence of defects across all tests implies that if problems exist, they are either intermittent or hidden behind a clean exterior. That said, the lack of advisories or failures on critical components over the past three years does not guarantee long-term reliability, particularly given the vehicle’s age and mileage. The Koleos has accumulated 143,267 miles over 17 years , averaging roughly 8,427 miles per year , which is broadly typical for its age. However, the gap between the 2024 and 2025 MOTs—just 13 months apart—is unusually short , suggesting the vehicle may have been driven more aggressively or that the owner delayed testing due to prior issues. The 2022 double-entry anomaly further complicates the picture, as it implies either a rushed or incomplete inspection. There is no evidence of rapid mileage accumulation, but the lack of advisories on wear items —such as tyres, brakes, or suspension—is striking for a vehicle of this age. This could indicate either meticulous maintenance or, conversely, that the tester overlooked subtle but critical wear. For a prospective buyer, the most pressing concern is the 2025 MOT failure without defects , which demands clarification from the seller. Beyond that, the suspension system —including coil springs, anti-roll bars, and bushings—should be inspected closely, as these components often degrade without immediate MOT consequences. The brake system , particularly the rear calipers and discs , warrants scrutiny, as binding or uneven wear can go unnoticed until it affects stopping performance. Structural corrosion , especially around wheel arches, sills, and exhaust mounts, should be checked for hidden rust that could compromise safety. Finally, the exhaust emissions system —given the lack of advisories—may need verification, as modern MOTs are stricter on CO2 and particulate levels. While the MOT history shows no major red flags, the inconsistencies in testing records and the absence of advisories on high-wear components raise questions about the vehicle’s true condition. A thorough pre-purchase inspection by a qualified mechanic is strongly advised before committing to this Koleos.
