How to read the schedule
That's BYD Australia's EV schedule, and CarExpert reports the same 12 months or 20,000 km for the Seal range. BYD's page adds a note that RWD and AWD cars require additional oils and filters. The Seal Premium is rear-wheel drive and the Performance is all-wheel drive, so ask the mechanic what's extra on yours. Your handbook is the final word for your car.
What makes a Seal service bigger or smaller
Which visit it is. A 40,000 km or 80,000 km service does a lot more than the ones either side, so compare estimates for the same visit.
Which Seal it is. The extra oils and filters above depend on the drive layout.
What the car has worn out. Tyres and brake pads sit outside the schedule. A Premium weighs 2,055 kg and a Performance 2,185 kg, with 390 kW on tap in the Performance, so tyres get a real workout. The tyre report at each service tells you what's coming.
Which Seal do you have?
The Seal reached Australia in 2023. BYD's page now lists the Essential, Premium and Performance, with the older Dynamic dropped in 2026. Packs of 61.4 kWh and 82.5 kWh have been listed, both BYD Blade LFP batteries. The grade and year are the first things a mechanic will want.
Warranty, and using an independent mechanic
BYD covers the Seal for 6 years or 150,000 km, and the traction battery for 8 years or 160,000 km, whichever comes first. Terms and exclusions apply. Having a qualified independent mechanic service it to BYD's schedule and specifications does not by itself void your new car warranty.
BYD's page points owners to its own service centres. If you'd like to use an independent, the practical test is whether they can do what the schedule lists, including the software update and the high-voltage checks. Ask before you say yes.
Questions for the mechanic
- How often do you work on high-voltage EVs, and BYDs in particular?
- Can you run BYD's software update, and if not, what's the plan?
- Which extra oils and filters does my Seal need at this service?
- Will the written estimate list everything BYD schedules for this visit?
