2009 MINI Cooper D 1.6L Diesel · LC09 FSF

The most recent MOT, carried out on 4 November 2025, was passed, but it still carried the same advisory concerning wear on the front suspension arm pin and both rear suspension bushes that has been recurring since 2021. Over the last five years the vehicle has alternated between passes and failures, with serious brake pad wear and a rear disc condition prompting a dangerous failure in 2023 and a lighting fault causing a failure in 2022. The pattern shows that while the owner has addressed the most critical safety failures, the underlying wear items have not been fully rectified, indicating a maintenance trend that is stabilising only after intermittent corrective work rather than improving comprehensively. At 135,789 miles recorded for a 2009 model the average annual mileage works out to just under 8 000 mi per year, which is typical for a car of this age. The figure does not suggest any period of extreme high‑speed use, but the relatively modest yearly total also hints that the car may have spent extended periods standing idle. Prolonged inactivity can accelerate corrosion of suspension components, promote rubber hardening in bushings and seals, and allow fluids to degrade even when mileage is low, so these aspects merit particular scrutiny. The recurring front suspension arm pin and rear bush wear should be inspected for any play when the wheels are rocked and for clunking noises over bumps; uneven tyre wear patterns may confirm the issue. Given the advisory has persisted for several years, replacement of the affected bushes and pins is advisable before they develop excessive movement that could affect handling and tyre life. The rear brake disc was noted as pitted and the inner rear pads were below the 1.5 mm safety limit in 2023; a competent garage should measure the disc thickness and inspect the pads for uneven wear, and the buyer should listen for any pulsation or shudder under braking, which would indicate that the disc may need resurfacing or replacement. Front tyre wear advisories from 2021 and 2022, together with the 2024 advisory that both front tyres are close to the legal limit, mean tread depth must be checked on the road – any reading below 3 mm warrants replacement, and sidewall cracking should be examined for age‑related perishing. The steering rack gaiter has been flagged repeatedly as deteriorated; a visual check for tears or fluid ingress, coupled with a feel for any looseness or binding in the steering, will reveal whether the rack needs resealing or a more extensive repair. Finally, the off‑side front position lamp fault recorded in 2022 should be verified as corrected, as lighting compliance is essential for legal road use. Beyond the specific MOT items, the buyer should conduct age‑appropriate checks: examine all tyre sidewalls for dry rot, especially if the car has been stored for long periods; test the 12 V battery voltage and consider a load test as batteries over ten years often lose capacity. Verify that coolant, engine oil and brake fluid have been changed within their recommended intervals – brake fluid should be refreshed at least every two years to prevent moisture absorption. Inspect the under‑carriage and suspension mounting points for rust, particularly around the rear subframe and wheel arches, and look for any signs of corrosion on the exhaust system. Confirm that the service book contains regular oil changes, timing‑chain inspections (the Cooper D uses a chain rather than a belt), and any turbo‑charger servicing, as a well‑documented history will give confidence that the vehicle’s critical mechanical systems have been maintained despite its age. A thorough test drive listening for any abnormal noises, monitoring for vibration, and checking that the engine idles smoothly will help verify that the car is mechanically sound before purchase.
