2012 BMW 520 2.0L Diesel · VA12 AAE

The most recent DVSA MOT test on 7 July 2026 resulted in a pass with no defects recorded, which represents a successful outcome for the prospective buyer following a prior failure on 1 July 2026. The earlier failure was attributed to a major defect concerning the offside rear suspension unit, classified as damaged or deteriorated with function affected. It is reasonable to assume that the suspension component was rectified between the two tests to enable the subsequent pass, although it remains important to verify the nature of the repair or replacement undertaken. Considering the broader test history, the maintenance trend over the past three years has been largely stable, with passes recorded annually and only one outright failure. The presence of a major suspension failure on the most recent attempt does, however, warrant close attention to the rear suspension assembly, as suspension components on a vehicle of this age and mileage are subject to progressive wear that can develop rapidly once deterioration initiates. The vehicle is fourteen years old with a recorded mileage of 150,310 miles, equating to an annual average of approximately 10,736 miles per year. This figure is broadly consistent with typical usage patterns for a vehicle of this age, suggesting neither prolonged periods of standing nor exceptionally heavy use. That said, the mileage places this BMW firmly in high-mileage territory, where wear on consumables, braking components, suspension assemblies, and drivetrain elements is to be expected. There are no significant gaps in the annual MOT testing pattern evident from the records provided, which indicates regular use and consistent annual inspection. A consistent MOT history is generally reassuring, as it reduces the likelihood of deterioration associated with long periods of inactivity, such as corrosion of brake components, tyre sidewall perishing, and fluid degradation through lack of circulation. Given the major suspension defect recorded at the offside rear, particular attention should be paid to the rear suspension assembly during a physical inspection and test drive. The failed component should be identified and inspected alongside adjacent bushes, coil springs, and mounting points to confirm whether the repair was comprehensive or merely addressed the immediate failure point. On a test drive, the buyer should listen for clonking or knocking noises from the rear suspension over undulating surfaces, speed humps, and during direction changes, as well as any signs of inconsistent ride height or excessive body roll that could suggest compromised damper or spring function. The advisory from June 2025 noting light oil misting on the offside front shock absorber is also relevant; while not a failure at the time, shock absorber oil misting typically progresses, and the front shock should be inspected for worsening seepage and checked for firmness by manually depressing each corner of the vehicle to confirm controlled rebound. Additional advisories from the 2023 test merit consideration even though they are older entries. The pitted and scored rear brake discs noted in that advisory are likely to have progressed given the intervening mileage and age, so the rear discs and pads should be physically inspected for wear, lipping on the disc edges, and any signs of brake shudder or pulsing under heavy braking on the test drive. The advisory concerning central front tyre wear on the edge is suggestive of potential wheel alignment or suspension geometry concerns, which could also relate to the rear suspension failure noted more recently. The repeated minor defect regarding the offside rear direction indicator lens suggests a possible recurring issue with that particular lamp unit, and the lens should be checked for secure fitment and water ingress. Beyond the recorded items, the prospective buyer should inspect all tyres for age-related sidewall cracking given the vehicle's fourteen-year production span, test the 12V battery under load as batteries of this age are prone to failure, examine the exhaust system for corrosion particularly at mounting points and joints, and verify the service history to confirm regular replacement of brake fluid, coolant, and transmission fluid in line with manufacturer schedules, as these fluids degrade with time irrespective of mileage.
