125kW Electric Motor (60Ah Battery) - Standard BEV
Electric
Listen for any clunking or clicking sounds when steering at low speeds or turning over bumps; this can sometimes indicate wear in the front suspension bushings or steering rack components common in older i3 models.
Cycle through all drive modes (Eco Pro, Eco Pro+, Comfort) while observing the dashboard for any 'Drivetrain Malfunction' warnings; these can appear due to minor sensor sensitivities in the older battery management systems.
Opening the bonnet and checking the condition of the 12V battery auxiliary tray; in older i3s, it is worth confirming that there is no moisture accumulation or signs of corrosion around the auxiliary battery terminals.
Testing the door hinges and latch mechanisms; given the i3’s unique coach door design, ensure they operate smoothly without sag, as adjustment might be needed as these vehicles age.
Consider a full diagnostic scan of the 60Ah battery health and check the condition of the cabin air filter.
Recommended interval to inspect the condition of the drive motor mounts and the regenerative braking efficiency.
Suggest an inspection of the coolant system, as the i3 uses a specific battery thermal management loop that benefits from fresh fluid.
Regularly monitor your tyre pressures, as the i3’s skinny, high-pressure tyres are sensitive and impact your range.
Keep the charging port area clean and dry to ensure smooth contact and prevent communication errors during charging.
Ensure your 12V auxiliary battery is tested annually, as its failure can prevent the main high-voltage battery from engaging.
Schedule a professional high-voltage system health report if the vehicle is nearing 100,000km to understand your state-of-health.
Keep the software updated, as BMW occasionally released improvements that optimize battery management for older modules.
Estimated repair costs if issues arise
Since the 12V battery powers the car's computers and triggers the main battery contactors, it's wise to budget for this replacement every 4-5 years. If this component needs attention, the estimated cost in NZ is usually quite manageable for a standard AGM unit.
Depending on the road conditions the car has faced, you might eventually need to budget for refreshing the front control arm bushings to restore that sharp BMW handling feel.
The i3 uses unique, narrow tyres that are specific to the model. If you need a full set, it's helpful to plan ahead as they are not always stocked locally in all centres.
