2022 BMW 840I M Sport Auto 3.0L Petrol · WN22 GPK

The most recent DVSA MOT test for this 2022 BMW 840i M Sport was conducted on 15 April 2026, at which the vehicle passed with no defects or advisories recorded. Prior tests in May 2025 and March 2025 also resulted in clean passes, indicating that the vehicle has maintained a strong and consistent roadworthy status over the inspection cycle. The only entry requiring buyer attention is an advisory issued on 4 March 2025 concerning a slightly deteriorated rear prop shaft flexible coupling. Because this was logged as an advisory rather than a failure, it would not have been grounds for refusal at the time, but it should be considered a forward indicator of wear on a driveline component that will likely require replacement in the medium term. Overall, the trend across the recorded tests is stable, with no recurrence or escalation of driveline issues, suggesting either a single isolated deterioration point or subsequent remedial attention by the keeper. The recorded mileage of 34,634 miles over approximately four years equates to an annual average of around 8,658 miles, which sits comfortably within the expected range for a premium grand tourer of this age and class. There are no glaring anomalies in the MOT history, such as extended gaps between tests with implausibly low mileages, which would otherwise suggest prolonged standing periods. The progression between tests is consistent and proportionate, and the mileage profile suggests a vehicle that has been used regularly for mixed driving rather than one subjected to either motorway-only high-mileage accumulation or infrequent short journeys. This is mechanically favourable, as regular use tends to keep seals lubricated, brake surfaces free from corrosion, and the battery in a healthy state of charge. Given the relatively clean MOT record and the moderate, consistent mileage, the principal buyer inspections should focus on age-related degradation rather than wear from excessive use. Tyres should be examined closely for sidewall perishing and cracking, particularly if the vehicle has been stored for any prolonged intervals, as premium and ultra-high-performance tyres fitted as original equipment can deteriorate from age even when tread depth remains adequate. The 12V battery, given the electrical demands of modern BMW electronics, should be checked for state of health and load capacity, especially if the car has seen any periods of standing. Brake discs and calipers should be inspected for any surface corrosion, binding, or uneven pad wear, as even lightly used vehicles can develop seized caliper pistons or pitted discs from infrequent braking cycles that lead to standing corrosion. The fluid servicing schedule is also highly relevant for a vehicle of this age, regardless of mileage. Brake fluid is hygroscopic and should be renewed typically every two years irrespective of use, while coolant, transmission fluid, and differential fluid (particularly relevant given the recorded prop shaft advisory, which may point to a rear-drive component requiring eventual service) should be verified against the manufacturer's calendar-based intervals. On a test drive, attention should be paid to any vibrations through the drivetrain at speed, clonks or shudders from the rear under load, and any roughness on ignition or gear selection, as the flexible coupling advisory indicates that the rear driveline has begun to show its age. A pre-purchase inspection by a specialist familiar with the 8 Series would be prudent to confirm the condition of the prop shaft coupling and to assess for any oil leaks from the engine, transmission, or rear differential, which are common areas of concern on these vehicles once they pass the four-year mark.
