2017 BMW 420 2.0L Diesel · CL13 ADE

The most recent MOT test on 27 March 2026 resulted in a pass, but the introduction of several advisories marks a departure from the clean inspection history seen between 2022 and 2025. While the vehicle has been consistently passing, the current advisories suggest that the maintenance trend is moving into a phase of age-related degradation. The appearance of suspension and tyre-related issues after several years of clean certificates indicates that the vehicle is entering a period where wear-and-tear components will require more frequent attention to maintain roadworthiness and safety. With 93,891 miles recorded over nine years, the vehicle has averaged approximately 10,432 miles per annum. This is a standard usage profile for a vehicle of this class, suggesting it has not been subjected to the extreme wear of high-mileage commercial use, nor the potential stagnation and fluid degradation associated with very low-mileage vehicles. This consistent usage is generally positive for the mechanical longevity of the engine and drivetrain, but it does mean the vehicle is approaching a mileage threshold where major service items and wear-and-tear components, such as suspension bushings and cooling system components, typically require replacement. The advisories regarding the offside front lower suspension arm ball joint having slight play should be your primary concern during a test drive. You should listen for any distinct knocking, clunking, or popping noises when driving over speed bumps or uneven surfaces, and feel for any looseness or lack of precision in the steering response. Additionally, the advisories for cracking and perishing on both front tyres indicate that the rubber is degrading due to age. Even if the tread depth is legally sufficient, perishing sidewalls can lead to structural failure. Inspect the tyres closely for deep cracks and check for any uneven wear on the outer edges, which may suggest that the wheel alignment or camber settings require adjustment, especially given the previous history of edge wear. In addition to the recorded defects, you should perform a comprehensive check of the braking system, looking for signs of heavily corroded discs or binding calipers that could cause uneven pad wear or pulling to one side. Given the vehicle's age, it is essential to verify that the service history includes timely replacements of essential fluids, such as brake fluid and coolant, which degrade over time regardless of mileage. Finally, check the condition of the 12V battery and ensure all electronic components are operating without fault, as the complex electrical architecture of this model relies heavily on stable voltage to function correctly.
