2005 BMW 520 2.2L Petrol · MV05 XYR

A persistent theme across the MOT record is gradual wear of the front braking system and the lower front suspension arm bushings, compounded by a recurring oil‑seal leak. The most recent test in October 2025 was passed, but the oil‑leak advisory remains, echoing similar notes from 2022, 2020 and 2018. Front brake disc condition has been flagged repeatedly since 2019, and the lower‑arm pins or bushes have been noted as worn but not yet causing excessive movement in four consecutive tests. Apart from a single emissions failure in 2017, the car has avoided outright failures for the last eight years, suggesting a pattern of manageable wear rather than acute mechanical breakdown. At 142,234 mi the vehicle averages roughly 6,800 mi per year, a mileage rate that sits comfortably within normal usage for a 21‑year‑old executive saloon. There are no significant gaps in the MOT chronology, indicating the car has been regularly inspected and therefore likely to have been driven consistently rather than stored for long periods. The moderate annual accumulation means consumables such as tyres, brakes and suspension components would be expected to show wear commensurate with the recorded advisories, but the mileage does not alone imply premature failure of major drivetrain or engine elements. Prospective buyers should inspect the source of the oil leak by looking for fresh oil stains on the engine bay floor and around the valve‑cover gasket, oil‑pan seal and any visible oil lines. During a static inspection, press the engine start button and observe whether oil drips appear after a short run; any persistent seepage may herald the need for gasket replacement or a more extensive seal overhaul. The front brake discs have been described as pitted or scored, and pads have been thin for several years, so a thorough visual check of disc surface for deep scoring and a measurement of pad thickness are essential. Listen for a high‑pitched squeal or feel for pedal pulsation under braking, which would indicate that the discs are nearing the end of their serviceable life and may require resurfacing or replacement. The lower front suspension arm pins or bushes, flagged as worn in four successive tests, should be examined for any lateral play when the wheel is rocked and for clunking noises over bumps. A test‑drive over uneven road should reveal any looseness or knocking that could point to imminent bush replacement. Tyre tread on both front and rear wheels was recorded as close to the legal limit on several occasions; verify current tread depth and inspect sidewalls for cracks or bulges before committing. The headlamp lens product and the non‑illuminating SRS warning lamp noted in 2022 merit a functional check—ensure the headlamp output is even and the SRS indicator illuminates on ignition. Finally, given the 2017 emissions failure for a misfire, confirm that the engine idles smoothly, accelerates without hesitation and that exhaust emissions appear clean, as lingering misfire issues could affect both performance and future MOT compliance.
