2020 BMW 520D M Sport Mhev Auto 2.0L Electric diesel · SL70 CPX

The latest MOT test on 2026-05-06 resulted in a clean pass, indicating that the vehicle has met all current roadworthiness standards without any failures. However, the preceding MOT history reveals a pattern of recurring advisories rather than outright defects, suggesting that while the car remains functional, several components are approaching or have exceeded their operational thresholds. The advisories from 2024 and 2025—particularly regarding brake pad wear, disc condition, and the rear propeller shaft flexible coupling—highlight areas of ongoing or developing concern. This trend does not indicate a sudden deterioration but rather a gradual progression of wear that requires proactive attention to prevent potential issues escalating into failures before the next MOT test. The vehicle’s recorded mileage of 106,590 miles at the time of this assessment represents a relatively high annual usage rate of approximately 17,765 miles per year, which is notably elevated for a six-year-old car. Such mileage accumulation over a short period can accelerate wear on critical systems, including brakes, suspension components, and drivetrain elements. The absence of significant mileage gaps—such as long periods of inactivity—suggests consistent, possibly heavy usage, which may have contributed to the observed wear on the rear propeller shaft coupling and brake components. Buyers should be mindful that this usage profile could lead to more frequent servicing needs, particularly for consumables like brake pads, fluids, and potentially the propeller shaft coupling if further deterioration is detected. Given the recurring advisories and the vehicle’s mileage profile, the prospective buyer should conduct a thorough mechanical inspection before purchase. Focus on the rear propeller shaft flexible coupling, as the 2024 and 2025 advisories indicate it is deteriorating. Listen for unusual noises during acceleration or when the engine is under load, as a failing coupling may produce clunking or rattling sounds, particularly when the vehicle is driven at higher speeds or over bumps. Additionally, examine the rear propeller shaft visually for cracks, excessive play, or signs of excessive wear, and consider having it inspected by a qualified technician to assess whether replacement is imminent. For the brakes, inspect the front and rear brake pads and discs for even wear and signs of glazing or scoring. Listen for a grinding noise when applying the brakes, which could indicate pad-to-disc contact or warping, and check for uneven brake pad wear that may suggest misalignment or binding calipers. If the pads are worn to the minimum legal thickness, replacement is strongly recommended to prevent excessive disc damage. Beyond the advisories, the buyer should also address the broader maintenance implications of the vehicle’s age and usage. Given the high mileage, inspect the suspension components for signs of wear, such as cracked or seized suspension bushes, coil spring failure, or excessive play in the control arms. Pay particular attention to the front suspension, as wear in this area can lead to steering instability or uneven tyre wear. Check the tyre condition thoroughly, including sidewall integrity for cracks, perishing, or signs of dry rot, which can compromise safety and structural integrity. The tyres should also be rotated to ensure even wear patterns, and the tread depth should meet or exceed the legal minimum of 1.6mm. Finally, verify the condition of the 12-volt battery and associated electrical systems, as prolonged inactivity or high mileage can lead to corrosion or degraded connections. Given the advisories from previous MOTs, it is prudent to confirm that all fluid levels—brake fluid, coolant, and transmission fluid—are topped up and free from contamination, as fluid degradation can accelerate component failure over time. If the vehicle has been driven regularly, calendar-based servicing intervals should be adhered to, particularly for fluid changes and filter replacements, to mitigate wear progression.
