2022 BMW X4 M40I Mhev Auto 3.0L Petrol · BD22 AAJ

The most recent MOT test on 6 August 2026 resulted in a pass with no defects recorded, indicating the car met the minimum statutory roadworthiness requirements at the time of inspection. On the same date, however, a separate failure was logged for a front windscreen wiper that did not clear the windscreen effectively, categorised under the prescribed reasons for failure. This is a relatively minor and easily rectified issue, typically caused by a degraded or perished wiper blade, a worn linkage, or a failing wiper motor, and would not generally point to any underlying mechanical concern. With only the two prior tests visible in the history, both recorded as passes, the maintenance trend appears broadly stable, with the wiper defect representing an isolated rectification rather than evidence of worsening condition across the vehicle's major safety systems. The vehicle is approximately four years old with 34,638 recorded miles, equating to around 8,660 miles per year on average, which is broadly typical for its age and consistent with mixed private and light commuter use. There are no significant gaps in recorded mileage, nor any rapid accumulation that would flag concerns about excessive wear on the drivetrain, clutch, or braking components. This level of usage suggests the vehicle has been driven regularly enough to keep seals, brakes, and mechanical components in working order, while not being so heavily used that major service items such as the timing chain, turbocharger, or suspension assemblies would be expected to show pronounced wear at this stage. The B58 inline-six engine and MHEV electrical architecture in the M40i are generally robust, but given the moderate annual mileage, it remains important to verify that all scheduled servicing has been carried out at the correct intervals. Given that the MOT record is otherwise clean and shows no advisories relating to tyres, brakes, suspension, or corrosion, the prospective buyer should focus on age and usage-related inspections that fall outside the MOT test scope. The tyres should be examined closely for sidewall perishing and cracking, as low-mileage vehicles and those regularly parked in exposed conditions can suffer dry rot from age even when the tread depth remains legal. The 12V battery and the MHEV auxiliary battery system should be checked for state of health, as modern BMW electrical architectures are sensitive to voltage irregularities, and a weak battery can produce a range of warning messages. All fluid conditions, including engine oil, coolant, brake fluid, and the ZF eight-speed automatic transmission fluid, should be inspected for degradation, with brake fluid in particular requiring replacement based on calendar age rather than mileage due to its hygroscopic nature. On a physical inspection, particular attention should be paid to the brake discs and calipers, as vehicles used for lighter journeys can suffer from corrosion around the disc hats and occasional caliper binding due to infrequent high-temperature operation. A test drive should include a thorough assessment of the all-wheel-drive system, the adaptive M suspension if fitted, and the active rear differential, listening for any clonks, knocks, or abnormal vibrations that may indicate worn control arm bushes, drop links, or anti-roll bar mountings. Any signs of fluid leakage beneath the vehicle, irregular idle behaviour from the B58 engine, or illuminated dashboard warnings relating to the mild hybrid system should be investigated promptly. Finally, verifying a full BMW main agent or specialist service history with documented digital entries in the iDrive system will provide reassurance that the vehicle has been maintained in accordance with manufacturer requirements.
