2013 BMW 520 2.0L Diesel · JIW 4084

The most recent MOT test, conducted on 2025-10-15, returned a clean pass with no recorded defects, marking a positive turnaround from the previous year’s failures. However, the vehicle’s history reveals a pattern of recurring suspension-related issues, particularly with front coil springs and suspension arm bushes, which were either fractured or excessively worn in two separate MOT failures. The 2024 test showed only advisories—worn but not critically damaged suspension bushes—indicating that the vehicle may have been nearing the end of their serviceable life before the latest inspection. While the overall trend has stabilised with no further major failures since 2024, the prior incidents suggest that the suspension components have been under significant stress, potentially due to heavy loading, poor alignment, or prolonged standing in a non-level position. The buyer should be cautious that these issues could re-emerge if the vehicle is subjected to rough road conditions or excessive wear on components like the track rod ends, which also failed in 2020. The recorded mileage of 74,180 miles for a 2013 BMW 520 is unusually low for its age, averaging just 5,706 miles per year—a rate that typically indicates either light usage or long periods of inactivity. Such low mileage can mask wear on consumables like fluids, which degrade over time regardless of distance travelled, particularly in a vehicle that has spent extended periods stationary. Additionally, standing in one position for prolonged periods can accelerate corrosion in brake systems, particularly on the offside front where the coil spring failed in 2020, as well as in the suspension and steering components. The lack of higher mileage figures suggests that the vehicle may have been kept in a garage or used infrequently, which could have contributed to the observed suspension failures, as standing can cause uneven wear on coil springs and bushings. The buyer should consider whether the vehicle’s maintenance history aligns with its reported usage, as discrepancies may point to neglect or misrepresentation. Given the vehicle’s history of suspension-related failures and advisories, the buyer must conduct a thorough inspection of the front suspension system. Start by visually inspecting the front coil springs for any signs of further deterioration, such as bulging or cracks, which could indicate imminent failure. Listen for clunking noises from the front suspension during cornering or over bumps, which may suggest worn or damaged suspension bushes or track rod ends. Check the alignment of the front wheels to ensure the suspension components are not misaligned, as this can exacerbate wear. Inspect the brake system, particularly the offside front discs and calipers, for signs of corrosion or binding, which could be exacerbated by prolonged standing. A test drive should include acceleration, braking, and cornering to detect any unusual vibrations, shuddering, or uneven tyre wear, which could indicate deeper issues with the suspension or drivetrain. For fluid checks, the buyer should verify the condition of the engine oil, brake fluid, and coolant, as these fluids degrade over time regardless of mileage. Given the vehicle’s age and the potential for prolonged inactivity, the brake fluid should be checked for moisture contamination, which can lead to corrosion in the brake system. The 12V battery should be tested for voltage and overall health, as low usage can cause the battery to degrade faster. A thorough inspection of the exhaust system for leaks or corrosion is also advisable, especially given the BMW’s tendency to develop rust in the catalytic converter or exhaust manifolds over time. Finally, the tyre tread depth should be checked alongside the sidewall condition, as low mileage can sometimes obscure signs of age-related perishing or cracking, which could compromise tyre safety. If any of these issues are found, prompt servicing or replacement of critical components is recommended to ensure the vehicle remains roadworthy and safe.
