2011 BMW 520 2.0L Diesel · LM11 NND

The most recent MOT test on 2026-02-04 resulted in a passing grade, with the only recorded advisory being a front oil leak at the engine, classified as not excessive. This follows a pattern of consistent MOT results over the past five years, with only one failure noted in 2021—an offside front track rod end ball joint exhibiting excessive play, which would have rendered the vehicle unsafe for road use at that time. While the 2021 failure stands out as an outlier, the subsequent MOTs have shown no further issues related to the suspension or steering components, suggesting that while the ball joint may have been compromised, it has either been repaired or the vehicle has been driven with caution to avoid further degradation of related systems. The vehicle’s recorded mileage of 131,799 miles at a typical annual usage rate of around 8,787 miles per year reflects a moderate, consistent driving pattern over its 15-year lifespan. This level of mileage is not unusually high for a BMW 520 of this age, particularly if the car has been used in mixed conditions, including city and highway travel, which can accelerate wear on suspension components, tyres, and drivetrain elements. However, the significant gap between the 2021 failure and the subsequent MOTs—nearly five years—could imply that the vehicle was either stored for extended periods or driven sparingly, potentially allowing minor issues to develop undetected before reaching critical failure points. For a suspension system that has already faced a major ball joint failure, this extended period without further inspection or maintenance may warrant closer attention to related components, such as the track rods, control arms, and bushings, which could be showing signs of wear or stress accumulation. Given the recent MOT passing and the absence of major defects, the buyer should prioritise a thorough mechanical inspection to verify the resolution of the 2021 ball joint failure. This involves checking for any residual excessive play or binding in the steering system, particularly around the offside front track rod end, and ensuring that the steering rack and tie rods are free from corrosion or excessive wear. During a test drive, listen for unusual noises such as clunks or rattles from the suspension, especially when cornering or over bumps, as these could indicate failing bushings or worn components. Additionally, inspect the front suspension for uneven tyre wear patterns, which may suggest misalignment or steering issues stemming from the ball joint failure. Fluid checks are also critical; the front oil leak advisory suggests monitoring the engine oil level and condition closely, as oil consumption can accelerate if the leak persists or worsens. If the leak is confirmed to be minor and contained, it may not immediately require repair, but the buyer should note it for future servicing. For the tyres, the recurring MOT advisories on near-side and offside front tyres worn close to the legal limit—particularly the edge wear—highlight a need for immediate attention. Edge wear typically results from underinflation, poor alignment, or excessive camber angles, all of which can be exacerbated by suspension issues. The buyer should measure the remaining tread depth and replace any tyres that are at or near the legal minimum of 1.6mm, as this will improve grip and prevent hydroplaning during wet conditions. Furthermore, the age of the tyres should be factored in; tyres over 10 years old, regardless of tread depth, should be replaced due to the degradation of the internal structure and the risk of sudden failure. Finally, given the vehicle’s age and the potential for standing corrosion—particularly in the front suspension and exhaust systems—visually inspect these areas for signs of rust or deterioration, especially around the wheel arches, brake calipers, and exhaust manifolds. A thorough check of the 12V battery health is also advisable, as older vehicles are more susceptible to battery failure from prolonged idling or standing, which can lead to electrical system issues or even the vehicle failing to start. Lastly, since the vehicle has not undergone a full service in recent years, the buyer should verify the presence of any service book stamps, particularly for fluid changes, brake servicing, and suspension component replacements, to ensure that time-based maintenance has been adhered to.
