2016 BMW 520 2.0L Diesel · AP16 PTY

The most recent DVSA examination on 29 September 2025 returned a Pass with no advisories or defects recorded, and the prior test on 28 October 2024 was similarly clean. Looking at the broader pattern, the vehicle has demonstrated a generally stable maintenance profile, passing six of the last seven tests without comment, but the 2023 episode is a notable exception and should not be dismissed. That earlier failure on 15 November 2023 recorded both rear road wheels as Dangerous due to fractured inner rims, followed two days later by a re-test Pass where the same wheels carried advisories for welding repairs. The rapid repair and re-test suggests the fractures were addressed, but any prospective buyer should treat welded wheels on a 143,000-mile car as a long-term concern regarding structural integrity, balance at speed, and the risk of progressive cracking returning. Aside from that single wheel-related cluster, the only other advisory in the entire history is a 2022 note that the rear brake pads were wearing thin, indicating normal service-interval consumption rather than any underlying fault. At 143,596 recorded miles over approximately ten years, this 520 is averaging around 14,360 miles per year, which sits firmly in the high-mileage bracket for a vehicle of its age. There are no significant gaps in the MOT record, with tests conducted annually and odometer readings progressing in a consistent, unbroken sequence, confirming that the car has been in continuous use rather than laid up. Sustained annual mileage of this level means that wear-related components such as suspension bushes, coil springs, anti-roll bar links, shock absorbers, brake discs and calipers, dual-mass flywheel or torque converter, and turbocharger-related hardware will have absorbed considerable fatigue. Diesel or petrol engine internals aside, the drivetrain, cooling system, and underbody will all have covered substantially more distance than the average equivalent, so a thorough inspection of these areas is warranted even though the MOT history itself does not flag them. From a buyer inspection perspective, the rear wheels are the obvious starting point. The welded repairs from late 2023 should be physically examined for signs of fresh cracking, distortion, or heat discolouration around the repair zone, and the wheels should be balanced and run at speed to detect any vibration or steering instability. The inner rim is particularly susceptible to fatigue failure, so a lift inspection to check for hairline cracks around the weld and along the rim flange is strongly advised, and budget for a replacement pair of wheels if any doubt remains. The 2022 advisory regarding rear brake pad wear should prompt a direct check of current pad material thickness and rear disc condition, as discs worn in tandem with thin pads may now be at or near minimum thickness and could require replacement. On a test drive, listen for any rear brake bind or drag on cold start, uneven pulling under braking, or shudder through the pedal, all of which would suggest seized caliper pistons or warped rear discs from the higher-than-average mileage. Beyond the recorded defects, the age and accumulated mileage demand attention to several time and distance-related service items. Tyres should be checked closely for both tread depth and, importantly, sidewall perishing or cracking given that rubber compounds degrade with calendar age regardless of mileage, particularly on a car that has seen ten UK winters. The 12-volt battery should be load-tested, as battery life is typically five to six years and an original or near-original unit on a 2016 car is well past its reliable service window. Brake fluid should be confirmed as recently changed, as it is hygroscopic and should be renewed every two years irrespective of use. Coolant, transmission fluid, and differential oil on this platform are all subject to calendar-based degradation and should be verified against the service book stamps, alongside evidence of cambelt or timing chain attention, injector servicing if diesel, and any turbocharger or EGR-related maintenance. Finally, a thorough underbody examination for corrosion, oil or coolant leaks from ageing gaskets and seals, and condition of the suspension arms and bushes will be essential to verify that this high-mileage example remains structurally and mechanically sound for continued use.
