2009 BMW 520 2.0L Diesel · MC09 COO

Recurring suspension and chassis-related advisories define the mechanical profile of this vehicle, with a noticeable trend towards wear in the lower suspension components and spring integrity. While the most recent test on 19 November 2025 resulted in a pass, the record shows a consistent pattern of deterioration in the anti-roll bar linkage ball joint dust covers, which have been flagged as severely deteriorated on both fronts for two consecutive years. This is compounded by previous advisories regarding corroded coil springs and worn rear suspension arm bushes, suggesting that while the vehicle remains roadworthy, the chassis and suspension assembly are entering a phase of increased component fatigue. The recorded mileage of 116,730 miles over approximately 17 years represents an average annual accumulation of roughly 6,866 miles. This usage level is relatively low for a vehicle of this age and type, which typically suggests more frequent, shorter journeys rather than high-speed motorway cruising. Mechanically, this pattern can sometimes lead to more frequent advisories regarding rubber components and suspension bushings, as seen in the history, because the components may experience more frequent movement cycles and environmental exposure relative to the total distance travelled. A prospective buyer should pay close attention to the suspension geometry and noise levels during a test drive. Given the repeated advisories for deteriorated anti-roll bar linkage dust covers and worn rear suspension arm bushes, listen for any rhythmic knocking, clunking, or knocking sounds when driving over uneven surfaces or speed bumps. The previous advisory regarding corroded coil springs warrants a visual inspection of the spring coils for significant surface rust or fractures, as failing springs can cause unpredictable handling or sudden breakage. Additionally, the most recent advisory for rear tyres worn close to the legal limit and worn on the edges suggests a potential for uneven tyre wear, which could be linked to the aforementioned suspension bushing issues. The electrical and visibility aspects of the vehicle also require scrutiny. The 2025 test identified a minor defect regarding a partially non-functioning multi-source lamp on the offside front and a damaged windscreen. During the inspection, verify that all lighting elements, including complex multi-source bulbs, are fully operational and that the windscreen damage does not compromise structural integrity or driver visibility under different lighting conditions. Finally, the 2018 advisory regarding limited parking brake lever travel should be checked to ensure the handbrake engages firmly and holds the vehicle securely on an incline, as this may indicate wear in the cable mechanism or rear brake adjustment.
