2015 BMW I3 0.6L Hybrid electric · OV65 OKB

The vehicle most recently passed its MOT on 30 July 2026 with no defects or advisories recorded, which represents a clean and reassuring outcome at the point of test. However, this clean pass follows a failed test just three days earlier on 25 July 2025, where a dangerous defect was identified in the form of a fractured nearside rear inner road wheel. While the vehicle subsequently passed on 28 July 2025, it is essential to verify that the replacement wheel was of the correct specification and that the remaining three wheels show no signs of similar fatigue, cracking, or corrosion, particularly given that a fractured alloy or steel wheel can be symptomatic of impact damage, prolonged kerbing, or material fatigue. The 2025 failure also flagged an advisory for a rear tyre worn close to the legal limit on edge, indicating uneven wear consistent with potential tracking, camber, or suspension geometry concerns, and a major fault relating to the supplementary restraint system warning lamp, which suggests an intermittent or historic airbag or seatbelt pretensioner fault that should be thoroughly diagnosed and cleared before purchase. The recorded mileage of 114,527 miles over an 11-year service life equates to an average annual usage of approximately 10,412 miles, which is broadly typical for a vehicle of this age and platform. The annual MOT records demonstrate steady and consistent accumulation of mileage year on year, with no significant gaps in usage that would suggest extended periods of standing. Regular use of this nature is generally beneficial for an electric vehicle such as the BMW i3, as consistent driving helps maintain battery conditioning, prevents brake disc corrosion from prolonged standing, and keeps suspension components free from seized joints. Nevertheless, at this mileage level, attention should be directed toward high-voltage battery health and capacity retention, as well as the condition of the electric drive unit and reduction gearbox, particularly given the known sensitivities of early i3 examples to drivetrain component wear. With an MOT history that is largely clean aside from the single 2025 failure and a small number of advisories, a physical evaluation of the vehicle should focus on age and mileage related wear items. The advisories recorded in 2021 noted front brake pads wearing thin, which at five years and around 80,000 miles would have required replacement; a prospective buyer should confirm that the front discs were also inspected or renewed at that time, as worn pads paired with scored or lipped discs indicate a brake service that may now be due again given the additional 30,000 miles covered since. The rear tyre edge wear advisory from both 2021 and 2025 is a particular point of interest, as recurring inner or outer edge wear on the same axle is often indicative of worn suspension bushes, weak coil springs, or alignment irregularities that a standard four-wheel alignment check would not always resolve. On a road test, listen for clonking or knocking from the rear suspension over uneven surfaces, and observe whether the vehicle sits level or shows any sagging at the rear, which could indicate degraded spring rates on this platform. Given the vehicle's age, particular attention should also be paid to time-based degradation items that an MOT will not necessarily cover in full. Tyre sidewalls should be inspected carefully for perishing or cracking, as rubber compounds degrade with age regardless of tread depth, and any tyre over five years old should be viewed with caution even if the tread remains within legal limits. The 12V auxiliary battery, which is critical for system wake-up and control module function on the i3, is a known failure point after approximately six to eight years and should be tested for state of health prior to purchase. Brake calipers, particularly on a vehicle that may have experienced periods of light use, should be checked for binding or seized slider pins, which can manifest as uneven pad wear, pulling under braking, or a hot wheel smell after driving. Finally, request evidence of recent servicing including brake fluid renewal, coolant replacement for the high-voltage thermal management system, and any diagnostic reports relating to the previously flagged airbag system, ensuring that all fault codes have been properly cleared and the system re-tested to confirm full functionality.
