2020 BMW I3 Electric · D3 COF

The most recent MOT, dated 21 January 2026, was passed but carried two advisories concerning slight damage or cracking of the near‑side and off‑side front tyres. Earlier in the series, the 1 December 2024 test also passed with no recorded defects, while the 18 October 2023 MOT showed a pass alongside a separate failure on the same day for excessive headlamp aim on both sides. Overall the trend is broadly stable: the vehicle has consistently cleared its annual test, with only minor, non‑fail items emerging in the latest inspection and a single, easily rectifiable lighting fault two years ago. At six years old the recorded mileage of 29,776 mi works out to just under 5,000 mi per annum, which is well below the typical usage for a small electric hatchback. Such low annual mileage often points to periods of limited use or prolonged storage rather than high‑stress driving. The modest wear implied by the mileage reduces the likelihood of accelerated degradation of wear items such as brake pads, clutch components or suspension bushings, but it also raises the possibility of age‑related deterioration—especially for rubber components, battery cells and any fluids that have been sitting for extended periods. Prospective buyers should give the front tyres immediate attention. Even though the advisories only note slight damage, the BMW i3’s tyre sidewalls can become brittle after several years, particularly if the car has been stationary for long stretches. Verify the tyre manufacture date on the sidewall, look for cracks, dry rot or uneven wear, and consider replacing both front tyres together to maintain balanced handling. While the headlamp aim issue recorded in 2023 has likely been corrected, a quick visual check of the headlamp lenses for clouding and a functional test of low‑beam alignment (ensuring the beam does not blind oncoming traffic) will confirm compliance. On a test drive listen for any irregularities such as a faint thump over bumps, which could indicate worn suspension bushings or deteriorating coil springs, and feel for any pull or vibration that might suggest tyre or wheel imbalance. Given the vehicle’s age and low mileage, time‑based maintenance is more critical than mileage‑based wear. Inspect the 12 V auxiliary battery for sulphation and confirm it holds charge, as batteries left idle for years can lose capacity. Examine the main high‑voltage battery coolant level and look for any signs of leakage around the cooling circuit. Check the brake discs for surface rust, especially on the rear side where the i3’s regenerative braking can leave discs idle for long periods; light surface corrosion is normal but deep pitting would require resurfacing or replacement. Finally, review the service book for evidence of regular oil, coolant and brake‑fluid changes, and verify that the vehicle’s software has received any manufacturer updates that affect range and charging performance. These checks will help ensure that the low‑mileage i3 remains mechanically sound and road‑worthy.
