📖BYD Seagull facelift: refined city EV with upgraded interior tech and chassis polish

BYD Seagull (facelift 2025) (2025-Présent)

The 2025 facelift sharpens the Seagull's appeal, refining cabin materials, updating onboard infotainment and optimising energy management for European and global markets. Preserving this practical urban commuter calls for regular BYD Seagull maintenance, focusing on suspension alignment and high-voltage electrical diagnostics.

Beneath the restyled bodywork lies BYD's durable Blade Battery, offered in 30.08 kWh and 38.88 kWh configurations, coupled with an integrated liquid thermal management system. Power reaches the front wheels through a refined reduction gearbox, while an upgraded heat pump enhances cold-weather cabin heating and driving efficiency.

When assessing a used Seagull facelift, confirm that the front tyres exhibit uniform tread wear across both shoulders. Ensure the 15.6-inch rotating screen responds crisply without lag, verify that the CCS rapid charging port latches cleanly, and inspect the auxiliary 12 V battery for consistent terminal voltage after overnight parking.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Exceptional LFP Blade Battery longevity and intrinsic safety against thermal runaway events.
  • Upgraded cabin ergonomics, enhanced acoustic insulation and responsive rotating central touchscreen.
  • Remarkably low running costs with minimal mechanical servicing requirements and frugal urban energy use.

Chronic weak spots

Keep an eye on
  • Front axle tyre wear: instantaneous electric torque on small wheels accelerates tyre scrub; monitor tread depth closely.
  • Rapid charging session stability: test DC charge handshake on public rapid chargers to ensure reliable communication.
  • Low-voltage 12 V battery health: check auxiliary battery state of charge periodically to prevent startup faults.
  • Underbody road spray protection: inspect exposed wiring harness sleeves and lower suspension links after winter driving.

Critical deadlines

Do not miss
  • Annual inspection and software diagnostic: complete multi-point check and OTA verification every 20,000 km or 12 months.
  • Brake fluid service: drain and refill hygroscopic DOT 4 brake fluid every 40,000 km or 24 months.
  • Tyre rotation and wheel tracking: rotate tyres front-to-rear every 10,000 km and verify steering alignment.
  • High-voltage cooling loop check: inspect thermal management fluid levels and pump function every 24 months.

Frequently asked questions about BYD Seagull (facelift 2025)

What servicing does an electric BYD Seagull (facelift 2025) need?
On a fully electric BYD Seagull (facelift 2025), periodic servicing is mainly a general inspection, an electrical-system check and a traction-battery diagnosis, plus brakes, tyres and the MOT. Garajo groups these checks and reminds you of each due date, for free.
How often should you check the electrical system and the battery?
The usual benchmark is every 15,000 km or 1 year, with a traction-battery diagnosis on the same rhythm (15,000 km / 1 year).
When should you change the battery coolant on a Seagull (facelift 2025)?
Garajo shows 120,000 km or 10 years. The interval can vary by manufacturer: always confirm in the handbook.
Does an electric Seagull (facelift 2025) need an oil change or a timing belt?
No. Those jobs apply to petrol and diesel engines. On a fully electric version, maintenance focuses on the electrical system, braking, tyres and safety checks.
How much does it cost to service a BYD Seagull (facelift 2025)?
The service budget for a BYD Seagull (facelift 2025) sits in line with the market average. Allow about 115 € for a full service, for example. Garajo estimates your budget by powertrain and tracks what you actually spend, for free.
Which BYD Seagull (facelift 2025) powertrain is best for town use?
This model is only available as electric. In town, electric versions fit best thanks to energy recuperation and the absence of cold-start cycles.
Which BYD Seagull (facelift 2025) powertrain should you choose if you mostly drive on the motorway?
This model is only available as electric. On the motorway in an electric version, look for the longest range and strong DC rapid charging.
