2016 BMW 420 2.0L Diesel · PX16 YTC

Recurring tyre wear patterns and a recent failure involving a missing wheel bolt define the mechanical history of this 2016 BMW 420. While the vehicle successfully passed its most recent MOT on 13 March 2026, the initial failure on that same date for a missing nearside rear road wheel fixing and a non-functional dipped beam headlamp highlights a lapse in basic pre-test preparation. Prior to this, the record shows a period of consistent passes, though the 2023 test flagged significant uneven tyre wear across the front axle, suggesting that the vehicle has experienced issues with wheel alignment or suspension geometry that warrant scrutiny. Accumulating 98,520 miles over a decade results in an average annual usage of approximately 9,850 miles, which is consistent with standard expectations for a vehicle of this type. This steady accumulation indicates that the car has been in regular operation rather than sitting idle for extended periods, which generally helps prevent the issues associated with long-term storage, such as seized brake components or degraded seals. However, the consistent use means that high-wear items like suspension bushings, dampers, and drivetrain mounts have reached a stage in their lifecycle where they are likely approaching or have exceeded their optimal performance window. Given the 2023 advisories regarding uneven tyre wear, a prospective buyer must prioritise a professional four-wheel alignment check. During a test drive, listen specifically for any knocking or clunking noises from the front suspension when traversing speed bumps or uneven surfaces, as this can indicate worn control arm bushes or ball joints that may have contributed to the previously noted tyre scrubbing. It is also advisable to inspect the inner and outer sidewalls of the current tyres for signs of irregular wear patterns, which would confirm if the underlying alignment issues have been rectified or remain an ongoing concern. The recent failure regarding the missing wheel fixing necessitates a thorough inspection of all wheel hubs and lug bolt threads to ensure no damage occurred during the period the fastener was absent. Furthermore, because the vehicle is now approaching the 100,000-mile threshold, the engine and underbody covers noted in the 2023 history should be removed to inspect for oil misting or leaks around the turbocharger and sump area, which are often obscured by these shields. Pay close attention to the steering response and ensure there is no vibration through the steering wheel at motorway speeds, as this could point to further issues with wheel balance or worn steering rack components that are common at this mileage.
