BYD Dolphin G DM-i warning lights and DTC research
Research status for warning lights, dashboard messages and diagnostic codes.
Skip to content
What is confirmed
No official Dolphin G DM-i DTC list or full warning-light chapter was extracted during this rollout. The public site therefore does not publish model-specific DTC pages, repair codes or generic OBD assumptions. Safe owner notes are limited to recording the exact dashboard message, driving/charging state, fuel level, SOC, outside temperature and contacting BYD service.
Scope and safety boundaries
Do not diagnose HV battery, hybrid system, fuel system, brakes, steering, airbags, ADAS, ECU, wiring or charging faults from community codes.
| Topic | Status |
|---|---|
| Official BYD model/spec facts | Published with citations |
| Manual text / warning icons / DTC | Review only until official manual extraction |
| Maintenance intervals | Requires VIN/manual/service confirmation |
Check market, trim, battery, software, VIN and official BYD/dealer confirmation. Safety-critical topics stay service-only.
Frequently asked questions
Is this page official BYD content?
No. It is an AutoTechHelp source-backed owner help page. Official BYD sources are cited at the bottom.
Does this apply to Dolphin EV or Dolphin Surf?
No. BYD Dolphin G DM-i is kept separate from Dolphin EV and Dolphin Surf unless an official source confirms overlap.
Where is the official owner manual?
BYD UK lists Dolphin G DM-i in the owner-manual selector, but the direct manual PDF/HTML still needs extraction or admin upload.
Are DTC codes published for this model?
No. Model-specific DTC pages are blocked until an official diagnostic or service source confirms exact codes.
Can I use this for an imported car?
Use it as a source map only. Confirm market, VIN, trim, battery, software and dealer support before applying a fact.
Are maintenance intervals confirmed?
Not as a full Dolphin G DM-i schedule in this rollout. Service topics are stored as confirmation-required until direct manual/service data is available.
Which trims have the larger battery?
Official UK specs list the 18.3 kWh battery on Boost, Comfort and Sport; Active is listed with 7.42 kWh.
Which trims have DC charging and V2L?
Official UK specs list DC charging and 3.3 kW V2L on Boost, Comfort and Sport, not Active.
Is this a repair guide?
No. HV battery, hybrid, fuel, brake, steering, airbag, ADAS, ECU, wiring and charging repair work is excluded.
How often are sources checked?
The seed stores checked dates and review tasks; dynamic pages and manuals should be rechecked as BYD publishes more assets.
