2018 BMW I3 0.6L Hybrid electric · YY18 OAZ

The most recent DVSA MOT test for this 2018 BMW i3 was conducted on 29 April 2026, resulting in a Pass, although four advisories were issued simultaneously. Each of the four fitted tyres was noted for slight damage, cracking, or perishing, which collectively represents a notable deterioration in the rubber compound. Reviewing the test history, the vehicle has passed every annual examination since 2021 with no recorded failures, indicating a generally well-maintained example. However, the advisory trend is clearly worsening; a single rear tyre perishing note appeared in 2022, was followed by an isolated rear tyre advisory in 2025, and then escalated to all four tyres being flagged in 2026. This escalating pattern of age-related rubber degradation warrants close attention from any prospective purchaser. The recorded mileage of 36,280 miles over approximately eight years equates to an annual average of around 4,535 miles, which is considerably below the typical usage profile for a vehicle of this age. This low annual mileage suggests either genuinely light running or extended periods of standing, both of which carry distinct mechanical implications for an electric vehicle. For instance, prolonged inactivity can accelerate sidewall cracking in tyres, degrade the 12V auxiliary battery through repeated shallow discharge cycles, and encourage corrosion on brake discs due to limited rotational movement and infrequent caliper actuation. Conversely, such low mileage places minimal mechanical stress on the high-voltage battery pack, electric drive unit, and suspension components, all of which would otherwise accumulate wear proportionate to use. Given the recurring and now multi-tyre advisory pattern, a thorough inspection of all four tyres is essential, paying particular attention to sidewall perishing, tread depth, and any uneven wear patterns across the axle. On a test drive, listen for any increase in road noise, which can indicate hardened or cracked rubber compound, and verify that the vehicle tracks straight without vibration through the steering wheel. Tyres manufactured before 2019 should be considered for replacement regardless of remaining tread, as rubber compounds typically degrade significantly after six to seven years regardless of mileage. Additionally, request documentation confirming tyre manufacturing dates, ideally looking for DOT codes indicating production within the last few years. Beyond the tyres, several age-related and standing-related checks are strongly recommended. The 12V auxiliary battery should be load-tested, as low-mileage EVs frequently suffer premature failure of this component due to parasitic drain without regular engine charging cycles. Brake discs and calipers should be examined for surface corrosion and ensure the calipers are not binding, which can be tested by rolling the vehicle on a slight incline with the parking brake released. Verify the service history for evidence of brake fluid replacement, coolant changes for the thermal management system, and any diagnostic scans of the high-voltage battery. Finally, confirm that all charging cables and equipment are present, and if possible, request a health report from a BMW specialist covering the state of the high-voltage battery, as this is the single most valuable component and any degradation directly impacts the vehicle's range and long-term viability.
