Navigate over uneven surfaces to listen for clunking from the front suspension, as the i3's unique lightweight chassis components can show signs of wear as they approach higher mileage.
Monitor the state-of-charge gauge during acceleration; a rapid drop in percentage might suggest the high-voltage battery health is beginning to reflect its age.
Observe the air conditioning and heater performance closely, as climate control issues are sometimes noted in units of this age due to the complexity of the heat pump system.
Inspect the tyres for 'sawtooth' wear patterns, as the narrow, high-pressure tyres are prone to uneven wear if wheel alignment has been neglected.
Usually marks the point where the original tyres may need replacement and the cabin air filter should be refreshed.
A common interval to have the drivetrain fluid inspected and to ensure the REx (Range Extender) engine, if fitted, has had its oil and spark plugs serviced.
Consider having the suspension bushings and steering components formally inspected during your next warrant of fitness.
Ensure the charging cable locks and unlocks smoothly at the port.
Verify that the digital instrument cluster remains bright and free of flickering.
Check the service history for regular brake fluid flushes, which are crucial for this model.
Confirm the 12V auxiliary battery has been replaced recently, as these often fail before the high-voltage pack.
Inspect the bodywork for any signs of carbon fibre composite stress or panel alignment issues.
Estimated repair costs if issues arise
Future Budget Planning: The i3 relies heavily on its 12V system to 'wake up' the high-voltage pack. If the car shows weird electronic glitches, you might eventually need to budget for a replacement to keep things reliable.
Future Budget Planning: Depending on the car's history and the condition of local roads, you might eventually need to budget for front control arm bushings or shock absorbers to maintain that signature smooth BMW ride.
Future Budget Planning: Because the i3 uses very specific, narrow-profile tyres, they aren't always sitting on the shelf at standard shops. It is worth setting aside funds for these unique tyres when the time comes to refresh them.
