1.5L B38 Turbo + Electric Motor
Hybrid (Petrol/Electric)
Inspect the alloy wheels closely for any signs of curb rash or structural damage; given the i8’s unique wheel design, they can be costly to refurbish or replace to factory standards.
Listen carefully for any rattle or ticking from the rear engine bay while in Sport mode; it is wise to ensure the 1.5L three-cylinder engine is running smoothly without unusual vibration.
Check the butterfly doors by opening and closing them multiple times; ensure the hydraulic struts hold firmly, as aging struts can become sluggish and require replacement.
Pay attention to the transitions between the electric motor and the petrol engine; verify that the hand-off is seamless and there is no hesitation or jerky gear changes during acceleration.
Consider a comprehensive cooling system health check and potential brake fluid flush.
A good point to inspect the hybrid battery state-of-health report via an official diagnostic tool.
Typically the time to assess suspension components such as bushings and shock absorbers for signs of wear.
Regularly verify the BMW service history to ensure the high-voltage electrical system has been inspected according to manufacturer intervals.
Keep an eye on the coolant levels for both the internal combustion engine and the high-voltage battery cooling circuits.
Ensure the 12V auxiliary battery is kept in good health, as these cars are quite sensitive to voltage drops which can cause spurious warning lights.
Periodically check the condition of the tires, as the unique size and compound requirements for the i8 can make finding stock a longer process.
Maintain the software updates through an authorized specialist to ensure the energy management systems are running optimally.
Estimated repair costs if issues arise
While these batteries are robust, it is prudent to set aside funds for potential long-term capacity degradation. If you eventually decide to replace or refurbish modules, this is a specialized task for EV-certified technicians.
Depending on the road conditions the car has faced, the sophisticated suspension setup may eventually require servicing or damper replacement to maintain that signature BMW ride quality.
In cars of this age, the fuel system components can occasionally show their mileage. If you notice cold-start issues, it is helpful to have a buffer ready for fuel system maintenance.
