2009 BMW 520 2.0L Diesel · A4 FGR

The BMW 520 presents a stable and highly reassuring maintenance trend, culminating in a completely clean pass recorded on 15 December 2025 at 118,293 miles. Across five consecutive annual tests, the tester flagged zero defects, advisories, or failures. This unblemished record indicates a vehicle that has been consistently maintained to a high mechanical standard, with no recurring faults or structural deterioration detected under official inspection. The maintenance trend is firmly stable, reflecting diligent ownership and prompt attention to any developing mechanical issues. The mileage accumulation aligns closely with typical usage for a 17-year-old saloon, averaging roughly 6,958 miles per year. Annual increments remain consistent, rising from 92,428 miles in December 2021 to 118,293 miles in December 2025. A slight uptick occurred between 2024 and 2025, covering 8,262 miles compared to the preceding 5,890 miles, though this remains within normal parameters for a touring vehicle. There are no suspicious mileage gaps or rapid spikes that would suggest odometer tampering or prolonged periods of disuse, pointing instead to steady, reliable service. Despite the flawless MOT record, a physical inspection remains essential for a 17-year-old executive saloon. Buyers should closely examine the condition of suspension bushes and coil springs, as these components degrade with age regardless of mileage. Brake discs and pads require scrutiny for corrosion and wear, particularly if the vehicle has spent extended periods stationary. The underbody and wheel arches must be checked for structural rust, while the exhaust system and emissions hardware should be assessed for leaks or deterioration common to vehicles of this era.
