2015 BMW 520 2.0L Diesel · BP65 KGY

The 2015 BMW 520 presents a generally stable maintenance profile, with the most recent MOT conducted on 16 December 2025 at 116,652 miles resulting in a pass. The tester flagged a light oil misting on the offside rear shock absorber, classified under item 5.3.2 (b). This is a minor advisory rather than a failure, indicating early-stage seal wear rather than catastrophic damper collapse. Across the five-year history from January 2022 through December 2025, the vehicle has consistently passed every test, suggesting the owner has addressed mandatory defects each year. The trend is broadly stable, though the recurrence of rear brake pad wear across multiple tests points to a pattern that warrants closer inspection. The mileage progression tells a coherent story. Between January 2022 at 72,879 miles and December 2025 at 116,652 miles, the vehicle covered 43,773 miles across roughly four years, averaging approximately 10,943 miles annually. This aligns closely with the 10,605 miles-per-year figure expected for an eleven-year-old vehicle. There are no suspicious gaps in the record that would suggest the car sat unused for extended periods, nor any sudden spikes in accumulation that might indicate exceptionally hard use. The MOT entries are current as of mid-December 2025, meaning the next test is due around December 2026, giving a buyer roughly six months of remaining cover from the last recorded test. A buyer should focus their in-person inspection on the rear suspension and braking system. Rear brake pads have appeared as wearing thin in both the January 2022 test at 72,879 miles and the February 2025 test at 106,248 miles, a span of over 33,000 miles. This recurrence suggests either a driving style that loads the rear axle heavily or a caliper issue causing uneven or premature pad depletion. The offside rear shock absorber's oil misting at the most recent test deserves particular attention. A misting condition can progress to full fluid loss, compromising damping performance and potentially affecting tyre contact patch stability under cornering or braking loads. Have a technician measure shock absorber damping and check the offside rear unit for wetness or dripping. The front suspension also merits inspection. Both nearside and offside front suspension arm pins or bushes were flagged as worn in the February 2025 test at 106,248 miles, though the tester noted no excessive movement at that time. Worn bushes introduce compliance into the front-end geometry, which can accelerate tyre wear and degrade steering precision. Check for cracking, perishing, or play in the front lower arm bushes and ball joints. The nearside front outer tyre worn close to the legal limit in the February 2024 test at 95,165 miles hints at possible alignment or suspension geometry issues that may have persisted. A four-wheel alignment check and thorough underside inspection for corrosion, particularly on subframes and mounting points, would complete a sound pre-purchase evaluation.
