Source-backed overview of the European SEAL U DM-i and what stays separate from EV and SEALION 6.
Quick answer
Source-backed overview of the European SEAL U DM-i and what stays separate from EV and SEALION 6.
Confirmed facts
| Topic | Source-backed position |
|---|---|
| Dmi Identity | SEAL U DM-i is the plug-in-hybrid Super DM branch; engine, fuel, EHS and HEV-mode facts do not apply to the EV. |
| Dmi Specs | DM-i Boost, Comfort and Design stay market-scoped. The official Europe page confirms Super DM, 18.3 kWh headline battery, 70 km plus EV range, up to 1080 km combined range and 18 kW DC charging. |
| Dmi Manual | The Netherlands and Romania LHD DM-i manuals are imported as official hybrid owner-manual sources and are summarized by chapter. |
| Not Merge | SEAL U, SEAL U DM-i, SEALION 6, SEAL sedan, SEALION 5/7 and Song Plus are not interchangeable content buckets. |
| No Dtc | No SEAL U-specific numeric DTC/error-code pages are published in this rollout because no official or authorized exact diagnostic source was found. |
Owner checklist
- •Confirm market, model year, trim, steering side and powertrain before applying a figure.
- •Use the official source links at the bottom for the current wording and documents.
- •Keep high-voltage, charging, braking, steering, airbag, ADAS, towing and rescue work with authorized BYD service.
- •For imported cars, verify VIN, software, charging standard and warranty registration locally.

Frequently asked questions
Is this official BYD text?
No. It is an AutoTechHelp editorial summary based on cited official or review-labelled sources.
Which version does it apply to?
Check whether the vehicle is SEAL U EV, SEAL U DM-i or Australia SEALION 6, then verify market, year, trim and steering side.
Can I mix Europe and Australia data?
No. Australia SEALION 6 facts are useful for comparison but remain AU/RHD-scoped until an official source proves exact equivalence.
Are DTC/error codes published?
No SEAL U-specific numeric DTC pages are published here without official or authorized diagnostic documentation.
Is this a repair manual?
No. Safety-critical systems remain service-only and the page intentionally avoids repair or wiring procedures.
What should I record before contacting service?
Record the exact message or icon, color, mileage, SOC/fuel level, charging or driving state, weather, recent service and accessory/software changes.
Why are some names left in English?
Trim names, DM-i, Super DM, V2L, DTC, ADAS and source market names are kept close to official wording to avoid mistranslation.
How often are sources checked?
AutoTechHelp stores checked dates and keeps safety-critical or conflicting topics in review until sources are strong enough.
Can imported cars use this page?
Use it as a source map and checklist, then confirm by VIN, local dealer support and the vehicle market record.
Are manuals copied here?
No. Manuals are linked and summarized in original wording; full manual text and protected images are not copied.
