2021 BMW 520D M Sport Mhev Auto 2.0L Electric diesel · LC07 ABC

The most recent DVSA MOT examination on 10 November 2025 resulted in a pass, with no failures or major defects recorded against this 2021 BMW 520D M Sport MHEV automatic. The only items noted were advisories relating to under trays and engine covers obscuring certain components from inspection, alongside rear tyre tread depth readings of approximately 3mm on the offside and 2.8mm on the nearside. Comparing this with the prior test on 29 October 2024, which carried identical under-tray and engine-cover advisories but no tyre wear concerns, the maintenance trend appears broadly stable with a predictable progression in consumable wear. No recurring structural, suspension, braking, or exhaust advisories are present, which is reassuring for a vehicle of this age and specification. The recorded mileage of 45,134 miles over a five-year period equates to an annual average of around 9,027 miles, which sits comfortably within typical usage parameters for a premium executive saloon of this class. There is no evidence of significant mileage gaps in the recorded MOT data, suggesting the vehicle has been in consistent use rather than left standing for prolonged periods. This pattern of regular driving is mechanically beneficial for components such as the 12V battery, brake discs and calipers, and the mild hybrid electrical system, all of which can deteriorate during extended inactivity. The relatively moderate annual mileage also implies that major drivetrain wear on the diesel engine and automatic transmission should not yet be a pressing concern, although the timing chain, turbocharger, and dual-clutch or torque converter elements should be considered for routine inspection as the vehicle approaches higher mileages. For a prospective buyer conducting a physical inspection, the primary attention should be directed toward the rear tyres flagged on the most recent test, as the recorded tread depths of 2.8mm and 3mm indicate they are approaching the legal minimum of 1.6mm and will require replacement imminently. On a test drive, listen for any uneven road noise or vibration that might suggest uneven tyre wear, and inspect the sidewalls for perishing or cracking consistent with the vehicle's age, particularly given the precision engineering and lower-profile M Sport specification. The advisories regarding under trays and engine covers are common on modern BMWs and do not indicate defects, but a buyer should request that these be removed during a pre-purchase inspection so that the front suspension arms, anti-roll bar links, subframe, and engine oil sumps can be examined for any fluid seepage or corrosion. Given that this is a five-year-old diesel hybrid with moderate mileage, several age-related service items warrant verification before purchase. Confirm the documented history for the diesel particulate filter regeneration cycles, AdBlue system function, and timing belt or chain service intervals as specified by BMW. Inspect the brake discs for any lipping or surface corrosion, particularly on a vehicle that may have been used for shorter journeys where full brake operating temperature is rarely achieved, and verify that the electronic parking brake releases cleanly without binding. Check the 12V battery state of health, as even on regularly driven vehicles the battery can deteriorate after five years, and confirm that the mild hybrid 48V system has no stored fault codes via a diagnostic scan. Finally, ensure that all time-based fluid services, including brake fluid (typically every two years), coolant, and automatic transmission oil, have been completed at the correct intervals as part of the manufacturer's scheduled maintenance programme.
