✅ 2025 Overview: BYD EV Network, Warranties, and Features
Maintenance of BYD electric vehicles (e.g., Dolphin and Seal ) is simpler than that of internal combustion engines, but requires attention to brakes, tires, software, and battery/inverter cooling circuits . In Italy, the service network and the availability of quality aftermarket spare parts are growing, especially for consumables (cabin filters, wipers, EV-ready pads, tires, fluids).
- Blade Battery (LFP): Stable chemistry and efficient thermal management; maintenance focuses on cooling and software updates .
- OTA & Diagnostics: Periodic updates can optimize charging, efficiency, and regenerative brake management.
- Aftermarket: For consumables and wear materials, you can choose OEM/Equivalent components. For HV/electronic parts, stick to approved spare parts and qualified workshops.

Note: Always check the official maintenance schedule in your BYD's owner's manual. Below is a useful maintenance schedule for workshop/user use.
| Kilometers / Time | Controls / Operations | Notes |
|---|---|---|
| 12 months / 20,000 km | Electronic diagnostics, OTA check, level and leak check, cabin filter (replacement/cleaning), tire and brake wear, tire pressure and rotation . | Advance for urban/heavy duty use. Rotate every 10,000–15,000 km to even out wear. |
| 24 months | Brake fluid (replacement), HV cooling circuit check (condition/replenishment), hub bearing inspection and alignment /geometry. | Low use of mechanical brakes can promote oxidation: deglazing / cleaning and guided lubrication recommended. |
| 36–48 months | Cabin filter change (pollen/activated carbon), check windscreen wiper condition, brake caliper service (sliding) and EV-ready discs/pads . | Choose pads with low noise and dust, with a coefficient suitable for regenerative braking. |
| 72–96 months* | HV refrigerant check/replenishment (battery/inverter) according to specifications, HV component check in qualified workshop. | *HV fluid replacement/service: Follow BYD instructions for your chassis. |
🧩 Recommended spare parts & purchasing suggestions
- Cabin air filters (HEPA/Activated Carbon): Improve comfort and protection of the evaporator and fan; change them more often if you use recirculation for heating/AC.
- EV-ready pads & discs: Optimized compounds for low operating temperatures and reduced noise; less dust → cleaner rims, less stress on ABS/wheel sensors.
- “EV-ready” tires: low rolling resistance, reinforced carcass for instant torque and battery weight, low-noise tread.
- DOT specified brake fluid: Hygroscopicity under control = constant pedal; replacement recommended every 24 months.
- Aero wipers: quiet at high speeds and on the highway, useful on Seal; check BYD compatibility clips.

❓ Frequently Asked Questions
Can I use aftermarket parts on BYD without losing the warranty?
For equivalent consumables (filters, pads, tires) there are no problems if they comply with the technical specifications . For HV system components and safety, stick to approved spare parts and authorized workshops.
How often do I change the brake fluid on a BYD EV?
Approximately every 24 months , with a boiling point test. Regenerative braking does not eliminate the need for hydraulic maintenance.
My discs are rusting because I'm braking too little: what do I do?
Perform light, prolonged braking periodically to clean the discs, schedule a caliper service , and consider low-noise EV-ready pads.
Which tires should I choose for Dolphin/Seal?
EV-ready tires with low rolling resistance , a reinforced casing, and low noise. Check the load/speed index and specifications in your vehicle documentation.
Do OTA updates affect maintenance?
Yes: they can optimize brake regeneration , thermal management, and fuel consumption. Keep your software updated and note the OTAs in your service log.
