2009 MINI 1.4L Petrol · LL09 XAS

The vehicle shows a history of recurring mechanical issues, particularly concerning the emissions and suspension. In the most recent test on 12 May 2025 at 154,004 miles, the car failed due to significant emissions failures. The tester recorded high hydrocarbon, carbon monoxide, and lambda readings all exceeding manufacturer limits, which often indicates a deeper engine management issue, failing catalytic converter, or oxygen sensor. While the vehicle passed a re-test the following day at 154,034 miles, it exited the MOT with a persistent advisory for a worn nearside front suspension arm bush, a fault that has appeared in three consecutive years. The mileage progression is consistent, averaging approximately 9,000 miles per year, which is typical for a 17-year-old vehicle. However, the record reveals a pattern of deferred maintenance on wear components. In May 2024, at 146,512 miles, the tester identified play in the nearside front steering linkage ball joint and a binding nearside rear service brake. The presence of corrosion on the rear sub-frame during that time is a structural concern for a MINI of this age, though it was noted as not yet seriously weakened. A buyer should be wary of the ongoing sub-frame corrosion and the state of the rear braking system. The failure for a deep cut in the nearside rear tyre in 2024 suggests basic upkeep was sometimes only addressed when prompted by inspection. Given the severe emissions failure in 2025, a professional diagnostic check of the exhaust and fuel system is necessary to ensure the pass was not a temporary fix of a larger mechanical failure that could recur shortly.
