2009 MINI 1.6L Petrol · LL09 LMJ

The most recent MOT test on 10 June 2026 resulted in a pass, although the examiner issued advisories for an oil leak (noted as not excessive) and worn rear anti-roll bar pins or bushes on both sides, alongside minor defects for the central stop lamp having a failed light source and water ingress within the lens. Looking at the broader history, the maintenance trend is broadly stable but with persistent and recurring minor issues that warrant attention. The oil leak advisory has appeared on every single MOT entry since at least June 2024, suggesting a chronic but currently minor seep that should be monitored. The stop lamp lens defect and partial light source failure have been flagged repeatedly across the last three tests, indicating a likely electrical or moisture ingress problem that the owner has not yet rectified. The more concerning event was the June 2025 failure, which included a dangerous nearside front tyre defect (a structural lump indicating separation of the tyre casing), a major offside front brake lagging defect, and major windscreen wiper failures in the preceding 2024 test. Although these were remedied to achieve subsequent passes, the brake issue in particular is a notable wear point worth investigating further. With 64,811 miles recorded on a 17-year-old vehicle, the annual mileage is approximately 3,812 miles, which is substantially below the national average and indicative of either light regular use or extended periods of standing. The MOT intervals are spaced roughly annually with mileage increments appearing relatively modest between tests, suggesting the car has been used consistently but sparingly rather than covering long distances. This low usage pattern carries its own mechanical implications. Vehicles that spend long periods stationary are prone to brake disc corrosion, binding brake calipers from seized pistons, and deterioration of the braking fluid through moisture absorption. The cooling system, brake fluid, and fuel system may all suffer from calendar-based degradation rather than wear-based degradation, meaning time-sensitive servicing items must not be overlooked simply because the odometer reading is low. For a prospective buyer, the persistent oil leak advisory should be physically inspected to identify its source, whether from the valve cover gasket, sump gasket, or front crankshaft seal, as even minor leaks can worsen over time and contaminate auxiliary drive belts or encourage residue build-up on the engine block. On a test drive, pay particular attention to the front suspension by listening for clunks or knocking over uneven road surfaces, which would indicate the worn anti-roll bar bushes flagged in the latest advisory progressing to a point of excessive play, and check for uneven tyre wear which often accompanies deteriorated anti-roll bar components. The offside front brake lagging defect recorded in June 2025 should prompt a thorough inspection of the brake system; during a test drive, listen for any grinding or squealing, feel for any pulling to one side under braking, and verify that the pedal feels firm and responsive without excessive travel. Inspect the rear brake calipers carefully for seizing, a common issue on low-mileage vehicles, and examine the brake discs for signs of corrosion or lipping which would necessitate replacement even if pad material remains. Beyond the recorded defects, this seventeen-year-old MINI warrants a comprehensive age-related inspection regardless of its modest mileage. Check all tyres for sidewall cracking or perishing caused by age rather than wear, as rubber compounds degrade with time and UV exposure, and verify the production date by examining the DOT markings on the sidewall. Inspect the condition of all visible coolant hoses, drive belts, and the auxiliary belt for surface cracking or brittleness, and consider a coolant flush and brake fluid replacement as a matter of course given the calendar age of the vehicle. The 12V battery should be load-tested, as batteries typically require replacement every five to six years and a failing battery can cause erratic electrical behaviour that might explain the recurring stop lamp issues. Verify the service book history to confirm that time-based items such as spark plugs, air filter, and cabin filter have been replaced at appropriate intervals, and request any available documentation regarding the rectification of the 2024 wiper failures and 2025 brake and tyre defects to ensure proper repairs were carried out using quality components.
