2012 BMW 520 2.0L Diesel · AF12 OBZ

The 2012 BMW 520 presents a currently roadworthy status with a stable maintenance trend. The most recent test on 20 February 2026 at 126,939 miles passed with no defects recorded, and the prior clean pass dated 25 February 2025 at 122,043 miles confirms no outstanding advisories have carried forward. The vehicle shows no worsening mechanical condition across the observed period. Mileage accumulation sits at a typical level for a fourteen-year-old executive saloon, averaging roughly 9,067 miles per year. The record moves from 116,966 miles on 5 February 2024 to 122,043 miles by February 2025, then to 126,939 miles by February 2026, equating to about 5,000 to 5,000 mile annual increments. No rapid accumulation or unexplained gaps appear between entries. The DVSA data itself is sparse on faults, with every pass and fail showing no defects recorded, which limits deeper wear inference from the sheet alone. The test history reveals a recurring pattern of initial failures followed by immediate passes at identical mileages, specifically the 3 February 2024 fail and 5 February 2024 pass, then the 19 February 2025 fail and 25 February 2025 pass, both with no defects logged. This suggests administrative or presentation issues at the testing station rather than mechanical rejection, though a buyer should verify the VIN and test certificate authenticity in person. Given the clean advisories, the buyer should still commission a physical inspection of suspension bushes, front coil springs, brake disc wear, and underbody corrosion, as a 126,939-mile BMW of this era commonly develops structural rust and worn arb links not captured by a defect-free MOT. No recurring consumable or structural faults appear in the official record to date. The previous keeper maintained the car to a passable standard at each annual cycle. A pre-purchase check of fluid condition, tyre sidewall ageing, and electronic suspension function remains prudent given the mileage and platform.
