2021 BMW 520D SE Mhev Auto 2.0L Electric diesel · DX71 BYO

The vehicle's overall roadworthiness is assessed as acceptable but with a significant risk of failure in the rear suspension and drivetrain, based on the most recent MOT test on 2026-04-27. The tester flagged binding rear brakes on this date, indicating that the brake discs and calipers may require replacement or adjustment to prevent catastrophic failure. This recurring issue suggests that the owner has been neglecting the braking system, which is a critical component for safety. The maintenance trend is not stable ; while the MOTs passed in late 2025 and early 2026, the failure in April 2026 represents a clear deterioration in the braking assembly that has not been corrected. The mileage pattern reveals a rapid accumulation of wear relative to the vehicle's age. At 82,337 miles, the car is approximately 16,467 miles per year, which is significantly high for a vehicle of this class. The gap between the 2026-04-27 test and the 2025-09-02 test indicates that the owner has not taken a break in driving or maintenance, leading to accelerated wear on suspension components and drivetrain parts. The lack of a 2026-06-18 test date means the most recent data points to the 2026-04-27 test, which is older than the current date, reinforcing the need to address the binding brakes and other mechanical issues immediately. Given the binding rear brakes and the rapid mileage accumulation, the buyer must inspect the car in person for the presence of structural rust, corrosion, or binding calipers . The history shows a pattern of failure where the rear suspension and drivetrain components are failing to hold loads, a condition that could lead to wheel spin or total loss of control. While the 2024-08-29 test passed, the 2025-09-02 test failed, showing that the condition has worsened since that date. A thorough inspection is required to identify any rust in suspension bushings, check the integrity of the brake disc, and verify that the suspension is not compromised by the rapid mileage gain. The buyer should not proceed with purchase until these mechanical risks are resolved.
