2018 BMW 5 Series 3.0L Diesel · BJ 1675

The most recent MOT, conducted on 27 April 2026, was passed with no recorded defects, confirming that the vehicle met the statutory safety and emissions standards at that time. The preceding year’s test also passed, although it carried two advisories concerning the near‑side rear shock absorber and the rear prop‑shaft flexible coupling. Across the five‑year MOT record the car has shown no outright failures, indicating a generally stable maintenance pattern with only minor, non‑critical issues emerging recently. At 45,755 miles on the odometer the 2018 BMW 5 Series has averaged roughly 5,700 miles per annum, a figure well below the typical UK usage of 10‑12 000 miles per year for a vehicle of this age. The low annual mileage suggests the car has been driven lightly or may have experienced extended periods of inactivity. Light use reduces wear on consumables such as brake pads, tyres and clutch components, but prolonged standing can accelerate age‑related degradation of rubber, seals and electronic components, and may promote surface rust on suspension and chassis parts. The advisory on the near‑side rear shock absorber noted a light misting of oil, which is an early sign of seal wear. On a test drive the driver should listen for a soft clunk when the rear suspension compresses over bumps and feel for any uneven rebound or excessive body roll, especially when cornering. Any noticeable oil spots on the rear wheel arch or a reduction in ride comfort would warrant a full shock inspection and likely replacement of the affected unit and its mounting bushes. The rear prop‑shaft flexible coupling was reported as slightly deteriorated and split; this component balances the torque between the gearbox and rear differential and, when compromised, can generate a humming or shuddering vibration that intensifies with acceleration. A thorough visual inspection of the coupling for cracks, excessive play or oil leakage, and a road test listening for drivetrain whine or judder, will help determine whether a replacement is imminent. Given the vehicle’s age and relatively low mileage, the buyer should also conduct age‑related checks irrespective of the MOT record. Examine all four tyre sidewalls for cracking, dry rot or hardening of the rubber, as tyres can deteriorate with time even when scarcely used, and verify that tread depth remains within legal limits. Inspect the 12 V battery for terminal corrosion and assess its charge holding capacity, since batteries tend to lose capacity after several years of storage. Look for surface rust on suspension arms, control‑arm bushes and the under‑carriage, and ensure that brake discs are free of deep pitting or excessive corrosion that could cause uneven pad wear. Finally, confirm that the service book shows regular oil, filter and coolant changes at the manufacturer‑specified intervals, and consider a comprehensive fluid change (engine oil, brake fluid, coolant and gearbox oil) if the last documented service exceeds 12 months, as fluids degrade with time regardless of mileage.
