2020 BMW 520D M Sport Mhev Auto 2.0L Electric diesel · AF70 VRV

The most recent DVSA MOT test for this 2020 BMW 520D M Sport MHEV Automatic was conducted on 24 September 2025 and resulted in a Pass, although a single advisory was issued concerning the offside rear tyre being worn close to the legal limit and exhibiting edge wear. Looking back over the recorded test history, the vehicle has now passed three consecutive MOT examinations with no failures or dangerous defects, suggesting a generally stable and well-maintained mechanical condition. The only recorded item of note is the tyre advisory from the latest test, and given that tyres are consumable components subject to regular replacement, this does not indicate any underlying mechanical deterioration. The overall trend is therefore one of consistent compliance rather than a pattern of worsening defects. With approximately 39,914 miles recorded over six years, this vehicle has covered roughly 6,650 miles annually, which is broadly typical for a car of its age and aligns with expected usage for a premium diesel saloon. The mileage progression across the MOT records is consistent and gradual, showing no sudden large jumps that might suggest commercial use, long-distance motorway commuting, or odometer irregularities. Diesel engines such as the 2.0-litre unit in the 520D are well suited to this kind of moderate annual mileage, and the mild-hybrid electrical system has likely seen regular but not excessive cycling. A test drive should confirm smooth power delivery, responsive automatic gear changes, and the absence of any warning lights relating to the diesel particulate filter or emissions system. Despite the clean MOT record, prospective buyers should not assume that a low-failure-rate history equates to a vehicle free from age-related deterioration, particularly on items not always thoroughly examined during the standard test. With six years of service life, the original 12-volt battery may be approaching the end of its functional lifespan, especially given that even healthy-looking batteries can lose significant cranking capacity, and the mild-hybrid system relies on stable low-voltage supply. Brake discs and calipers can suffer from corrosion or light binding due to standing periods or limited use, so a test drive should include several firm stops from moderate speed to check for juddering, pulling to one side, or any grinding sensation. The steering should feel precise without clonks over uneven surfaces, and the suspension should remain quiet and composed. Additional physical checks should include a close inspection of all four tyres for sidewall perishing or cracking, which is common on vehicles of this age regardless of tread depth, and confirmation that the offside rear tyre highlighted in the 2025 advisory has been replaced with a matching specification. Brake fluid, coolant, and transmission fluid should be verified as recently serviced according to manufacturer schedules, as these degrade over time irrespective of mileage. Diesel-specific items worth inspecting include the condition of the timing belt or chain service interval if applicable, the turbocharger for any signs of oil seepage or whistling under load, and the underbody for any corrosion around suspension mounting points and exhaust hangers. Ensuring that the vehicle has a fully stamped service book and that any diagnostic trouble codes have been cleared will provide further reassurance of its overall mechanical integrity.
