Plug the vehicle into both an AC wallbox and a DC rapid charger during the inspection to verify negotiation and charging initiation. | Note: On-Board Charger (OBC) failures are common on B9 Partner EVs. A faulty OBC will prevent AC charging entirely or trip home circuit breakers, and replacement units are highly expensive and difficult to source in NZ.
Drive over speed bumps and rough Kiwi bitumen at low speeds, listening for clunking, squeaking, or knocking noises from the front end. | Note: As a commercial van, these vehicles are often driven hard and fully loaded. The front suspension bushings, lower control arm bushes, and drop links wear out prematurely under heavy load conditions.
Turn the climate control to maximum heat immediately on startup and ensure hot air blows within a minute. | Note: The High Voltage PTC cabin heater is prone to failure on these models. If it fails, you will have no heating or windscreen demisting, which is a major safety issue and a failure for a NZ Warrant of Fitness (WOF).
Request a certified State of Health (SOH) battery diagnostic printout from an EV specialist before purchase and verify the real-world range. | Note: The 22.5kWh traction battery generally holds up well, but heavy DC rapid charging or constant operation at maximum payload can accelerate capacity degradation, directly reducing your real-world driving range to under 100km on NZ roads.
Perform first minor service: replace cabin pollen filter, inspect high-voltage cables and connections, check 12V auxiliary battery health, and inspect brake pads/discs (though wear should be minimal due to regenerative braking).
Replace brake fluid, inspect and lubricate brake caliper slide pins to prevent seizing from under-use, check the suspension component integrity, and perform a full diagnostic scan of the electric motor drive systems.
Perform a comprehensive traction battery SOH test, replace the traction motor cooling system fluid, inspect drive shafts and CV boots for wear, and replace the reduction gear oil to ensure transmission longevity.
Regularly lubricate and service the mechanical brakes to prevent caliper binding, as regenerative braking means the physical brakes are rarely worked hard.
Monitor the state of the 12V auxiliary battery; a weak 12V battery is the leading cause of 'Electrical System Failure' warning lights and failure to start the EV system.
Keep cowl drains clear of debris to prevent water ingress from damaging the sensitive electronic modules located in the engine bay compartment.
Inspect the integrity of the orange High Voltage cable orange conduits underneath the chassis for scrape damage from gravel roads or high curbs.
Perform annual wheel alignments to prevent premature or uneven wear of front tyres, which take a beating due to the instant torque of the electric motor.
Estimated repair costs if issues arise
If AC charging fails, the internal OBC must be replaced. This requires specialist diagnostic programming and high-voltage isolation procedures.
A failed cabin heater element requires replacement of the heater matrix, which is labor-intensive as it involves pulling down the dashboard assembly.
The battery and motor cooling system uses a specific fluid that must be flushed and refilled using proper diagnostic bleeding equipment at specialized service centers.
