BYD Dolphin Service Cost and Schedule Guide
Share
The BYD Dolphin has its first check at three months or 5,000 km, typically complimentary, then services every 12 months or 20,000 km. Under BYD's capped-price servicing, minor visits cost about $165 and major visits around $498, with the largest about $635. The owner's manual sets the underlying schedule: brake fluid every two years, motor coolant every four years, and transmission oil from 24 months, which is exactly why every second service costs more.
BYD Dolphin Servicing at a Glance
| Measurement | Detail |
|---|---|

| Brake fluid replacement | Every 2 years or 40,000 km |
The Service Intervals, From the Manual
The Dolphin's maintenance schedule comes straight from the owner's manual, and it follows a clear rhythm: a first check at three months or 5,000 km, a second at 12 months or 20,000 km, then a repeating cycle, with mileage or months applying, whichever comes first.
| Measurement | Interval (per the manual) |
|---|---|
| Tyre pressures | Check at least monthly |
| Tyre rotation | Every 10,000 km |
| Brake pads and discs, tyres, TPMS, coolant level, brake fluid condition | First at 3 months / 5,000 km, then every 12 months / 20,000 km |
| Suspension, steering, brake hoses, wheel alignment, bearings | First at 3 months / 5,000 km, then every 24 months / 40,000 km (12 / 20,000 in severe use) |
| Brake fluid replacement | Every 2 years or 40,000 km |
| Transmission oil replacement | First at 24 months / 40,000 km, then every 24 months / 48,000 km |
| Drive motor coolant replacement | Every 4 years or 100,000 km |
| Battery pack capacity test | Every 6 months or 72,000 km |
What Each Service Costs
Under BYD's capped-price servicing, published through its Australian service network, the Dolphin's visits alternate between inexpensive minor services and fuller major ones.
| Measurement | Typical cost (market) | What it covers |
|---|---|---|
| First check (3 months / 5,000 km) | Typically complimentary | Initial inspection and fastener checks |
| Minor service (12 months / 20,000 km) | About $165 | Inspections, checks, and consumables |
| Major service (24 months / 40,000 km) | About $498 | Inspections plus fluid replacements |
| Largest major | About $635 | Where the bigger replacements stack up |
Averaged out, that is a few hundred dollars a year, cheap by petrol-car standards. Prices vary by state, provider, and model year, so confirm current capped prices with your BYD service centre.
Why Every Second Service Costs More
Here is the insight that connects the two tables, and it comes straight from the manual. The expensive services are not arbitrary: they land exactly where the manual's replacement intervals fall due.
- Brake fluid: Replaced every two years or 40,000 km, which is every second service
- Transmission oil: First replaced at 24 months or 40,000 km, the same visit
- Motor coolant: Replaced every four years or 100,000 km, joining a later major
So the roughly $165 visits are inspection years, and the roughly $498 to $635 visits are the ones where fluids are actually replaced. Understanding this rhythm means no surprises at the service desk.
The Fluid Specs Your Workshop Needs
The manual publishes the exact fluids, and few service guides do. These are worth keeping handy for any workshop visit.
- Transmission oil: Castrol BOT384, 450 ml (Standard Range) or 600 ml (Extended Range)
- Brake fluid: HZY6, 1,100 ml
- Motor coolant: Glycol organic acid coolant, minus 40 degree freezing point, 3.1 or 3.3 litres
- A/C refrigerant: R1234yf, 1,000 grams
Using the specified fluids keeps the car serviced to BYD's standard and protects your warranty position.
Between Services: The Owner's Share
A few simple items sit with you between visits, and they keep the car healthy.
- Tyres: Check pressures monthly and rotate every 10,000 km per the manual
- Wipers: The manual advises checking the blades every six months or 10,000 km, and replacement is an easy job
- Cabin freshness: Replacing the cabin filter periodically keeps the ventilation clean, another simple swap
- Washer fluid: Top up as needed
Quality wiper blades and cabin filters for the Dolphin make these between-service jobs quick and inexpensive.
Severe Conditions Shorten Some Intervals
One manual detail worth knowing: if the car regularly sees muddy, sandy, snowy, or dusty roads, or carries a roof rack, several 24-month items move to a 12-month or 20,000 km cycle. If that sounds like your driving, mention it at booking so the schedule is applied correctly.
How the Dolphin Compares
As a pure EV, the Dolphin sits at the cheap end of servicing, with no engine oil, spark plugs, or exhaust to maintain. For the wider picture across the range, our breakdown of average BYD service costs in Australia compares every model, and our guide to the Shark 6's service schedule shows how the plug-in hybrid ute's petrol engine adds to the bill, a useful contrast with the Dolphin's simplicity.

Common Mistakes
- Skipping the first check: The 3 month or 5,000 km visit is quick, typically free, and part of the schedule
- Budgeting only for minors: Every second service is the fluid-replacement visit at a higher price
- Forgetting months count too: Intervals apply by time or distance, whichever comes first
- Ignoring the severe-use rule: Dusty roads and roof racks shorten several intervals
- Using unspecified fluids: The manual names exact fluids, so insist on them
- Neglecting tyre rotation: Every 10,000 km keeps wear even and tyres lasting longer
