150kW (204hp) Electric Motor - Extended Range/Sport
Electric
Listen carefully for any subtle rattles from the rear suspension over speed bumps, as early generation models have been reported to exhibit some stiffness that may warrant checking the bushings.
Cycle through the 'Vehicle Settings' on the infotainment screen to ensure the screen responsiveness is smooth, as occasional software lag has been noted by some users.
Test the regenerative braking levels on a quiet stretch of road; ensure the transition between friction brakes and regen feels predictable and consistent to your driving style.
Check the 'Vehicle-to-Load' (V2L) adapter if included; ensure the connection is secure and the power output is stable, as the adapter contacts can occasionally show signs of wear.
Initial chassis inspection and tyre rotation check.
Brake fluid flush and cabin air filter replacement.
Detailed inspection of the battery thermal management system and coolant health check.
Full drivetrain inspection and alignment check for suspension wear.
Regularly wipe down the infotainment screen with a microfibre cloth to keep the sensors sensitive and clean.
Check tyre pressures monthly; the Dolphin is sensitive to pressure variations which can impact the efficiency of that 150kW motor.
Keep your charging port area clear of dust and debris to ensure the locking mechanism functions reliably.
Monitor the tyre tread depth closely, as the higher torque of the Extended Range trim can lead to slightly faster front tyre wear.
Every six months, verify the software version in the system settings to ensure you are receiving the latest performance optimisations from BYD.
Estimated repair costs if issues arise
Because the Extended Range model has a bit more pep, you might find the front tyres wear down a little faster than expected. It is smart to start a small fund for a set of high-quality EV-rated tyres when the time comes.
For comfortable commuting in NZ air quality, you will want to swap your pollen filter regularly. It is a straightforward task, but good to keep in mind for your annual service budget.
Even though regenerative braking helps, the physical brake pads and discs still need a health check to ensure they remain free of corrosion from our humid NZ coastal air. It is good practice to budget for an occasional clean and service.
