2008 BMW 520 2.0L Diesel · OV58 AFU

The vehicle most recently passed its MOT on 28 February 2026 with several advisories recorded, primarily relating to worn front suspension arm pins or bushes on both sides and minor discolouration of the front and side direction indicators. While the test outcome itself is favourable, the pattern of advisories across recent tests indicates a maintenance trend that is gradually worsening rather than stable or improving. Over the past three years, the records show recurring issues with anti-roll bar linkage ball joint dust covers, deteriorating rear brake hoses and corroded brake pipes, and a fractured front coil spring in early 2023. The accumulation of suspension and brake line advisories, alongside a minor defect for the anti-roll bar linkage, suggests the chassis and underbody components are beginning to reach a stage where proactive replacement would be prudent before they escalate into test failures. The recorded mileage of 342,894 miles over approximately 18 years equates to an annual average of around 19,050 miles, which is notably high for a vehicle of this age and points to consistent, sustained use rather than long periods of standing. There are no significant gaps in the MOT history indicating lay-ups, and the relatively even annual coverage means consumables, braking components, suspension wear items, and drivetrain parts have all accumulated substantial real-world usage. This level of mileage on a diesel or petrol E60-generation BMW 5 Series typically translates to considerable wear on the clutch, automatic transmission torque converter and fluid, dual-mass flywheel if applicable, turbocharger if fitted, and engine ancillary components, all of which warrant careful scrutiny despite any absence of specific advisories relating to them. Given the recurring advisories around the front suspension, anti-roll bar linkage, and rear brake hoses, a prospective buyer should carry out a thorough physical inspection and a careful test drive. The worn front suspension arm pins or bushes should be checked by hand for any discernible lateral or vertical play when the wheels are rocked, and the front anti-roll bar drop links should be examined for perished or split dust covers and any knocking or rattling noise transmitted through the body over uneven road surfaces. Coil springs, particularly on the front axle given the prior fractured spring, are a known wear item on high-mileage E60s and should be inspected for signs of corrosion pitting or sagging; a fractured or weakened spring will often produce a noticeable clonking over speed humps and uneven tyre wear across the tread face. The rear brake hoses and brake pipes should be closely examined for surface cracking, blistering, or corrosion under any protective coating, and the brake pedal should be tested for a firm feel without excessive travel, as perished hoses can lead to spongy braking and loss of pressure under heavy application. Beyond the recorded advisories, the high annual mileage and age of the vehicle mean several time- and usage-based items require attention regardless of MOT outcome. Tyres should be checked for both tread depth and, critically given the vehicle's age, sidewall cracking or perishing from rubber degradation, even if the tread remains legal. The 12V battery should be load-tested, as batteries beyond five years of service frequently fail without warning, particularly in vehicles with high electrical load from comfort and infotainment systems. Brake discs, particularly the rear ones, should be inspected for corrosion lips at the friction edge, as standing moisture in the caliper area combined with infrequent heavy braking can lead to binding calipers or uneven pad transfer. All fluids including engine oil, coolant, brake fluid, and if applicable automatic transmission fluid should be verified for recent servicing, as brake fluid is hygroscopic and degrades over time irrespective of mileage, and a neglected cooling system on a high-mileage BMW is a common precursor to water pump, thermostat, and expansion tank failures. Finally, verifying a full and consistent main dealer or specialist service history with stamped intervals matching the mileage will be essential to confirm that the engine, gearbox, and drivetrain have received the regular attention this high-mileage example demands.
