2009 BMW 120 2.0L Diesel · AFZ 7015

A pattern of recurring advisories rather than outright failures defines the roadworthiness profile of this 2009 BMW 120. Across the five recorded examinations, the car has never failed an MOT, yet almost every test has surfaced items requiring attention, painting a picture of a vehicle that remains legally compliant but is mechanically ageing in a predictable manner. The most recent pass on 22 December 2025 captured five advisories covering a non-excessive oil leak, thinning rear brake pads on both sides, a noisy exhaust, and a headlamp lens with product residue reducing light output. This continues the trajectory established by the 2025 and 2024 tests, where steering rack play, sub-frame corrosion, edge wear on multiple tyres, and worn rear suspension arm pins or bushes were all flagged. Only the 2023 examination stands out as entirely clear, suggesting a brief window where no notable deterioration was recorded before the wear items began accumulating again. At 168,065 miles over roughly seventeen years, the vehicle has averaged close to 9,900 miles annually, which sits broadly in line with typical usage for a car of this age. There are no extended gaps between tests that would imply long periods off the road, and the spacing of the examinations is consistent with a continuously used vehicle. This steady, moderate annual mileage means the mechanical wear visible in the records is the expected outcome of gradual accumulation rather than a sign of either light preservation or hard use. Consumable items such as brake pads, tyres, and suspension bushes have predictably reached advisory thresholds multiple times, and the drivetrain at this odometer reading will be carrying the cumulative effects of sustained service. For a prospective buyer, the rear suspension is the area that warrants the most careful physical inspection. The 2024 test recorded worn pins or bushes on both sides of the rear lower and upper suspension arms, and these are common failure points on E81 and E87 platform BMWs of this vintage. On a test drive, listen for clonking or knocking noises from the rear over uneven surfaces, particularly when travelling at low speed over speed humps, and feel for any vagueness or delay in the rear end responding to steering inputs. With the vehicle unladen, push laterally on each rear wheel at the top and bottom to check for play in the bushes, and visually inspect the trailing arm and control arm bushes for cracking, splitting, or separation of the rubber from the metal housing. The offside front steering rack inner joint play flagged in January 2025 is also worth probing; a knock or rattle through the steering when traversing rough roads, or a slight looseness when turning the wheel with the car stationary and the wheels just off the ground, would indicate the joint has deteriorated further and may require replacement. The other recurring items in the record should be addressed in a pre-purchase inspection without disproportionate alarm. The oil leak noted in both 2022 and 2025 is described as not excessive, but oil leaks in BMW N-series engines of this era frequently trace to the valve cover gasket, oil filter housing gasket, or sump gasket, and a close visual check for fresh oil residue on the engine block, sump, and surrounding components is worthwhile. The rear brake pads thinning on both sides suggests replacement is imminent, and the discs should be measured for wear ridge and minimum thickness at the same time. The sub-frame corrosion noted on the 2025 test was not classed as seriously weakened, but sub-frames on these vehicles can deteriorate quickly once surface corrosion is established, so a thorough check of the mounting points, mounting bolts, and surrounding structural areas for any flaking or section loss is advisable. Finally, confirm that the headlamp product residue flagged in December 2025 has been cleaned or restored, as obscured headlamp lenses are a straightforward MoT failure once light output becomes seriously reduced, and the noisy exhaust should be inspected for any blowing joints, heat shield rattle, or signs that a replacement is approaching.
