BYD Dolphin Surf airbag control unit repair(1)

What should I pay attention to with BYD Dolphin Surf airbag control units?
The airbag control unit in the BYD Dolphin Surf evaluates the crash sensors, triggers the airbags and monitors the entire airbag system. If it detects a fault, the airbag warning light in the instrument cluster comes on. Airbag24 repairs the control unit you send in.
After an accident, the control unit stores crash data and locks itself. The airbag warning light can then stay on permanently. Erasing the crash data is part of our repair service.
The airbag system is safety-relevant. Do not carry out work on the control unit yourself; leave it to a specialist workshop. For a BYD Dolphin Surf airbag control unit repair, you send in your own unit, and Airbag24 checks and repairs it. Whether a particular unit can be repaired only becomes clear after testing.
Which BYD Dolphin Surf generations are there?
For the BYD Dolphin Surf, only one generation is currently distinguished: the 1st generation. It has been built since 2025 and is still in production. The build year of your vehicle is decisive for the assignment.
The model name alone is not sufficient for assignment. The build year and equipment of your vehicle are also decisive.
- 1st generation (since 2025) – the current series of the BYD Dolphin Surf, built to this day.
How do I identify my BYD Dolphin Surf airbag control unit?
The part number on the label of the control unit determines the exact version. The build year and equipment of your vehicle are also relevant. With these details, the correct unit can be reliably identified.
The label is located on the housing of the control unit. Note down the full part number before you send in the unit, and have the vehicle identification number (VIN) to hand.
Fault codes provide a first indication. Examples are B1600 for an unconnected driver front airbag, B17A800 for an interrupted CAN bus connection and B1694 for a supply voltage that is too low. However, a single code does not prove a defect in the control unit.
What airbag equipment does the BYD Dolphin Surf have?
The BYD Dolphin Surf comes as standard with driver and front passenger airbags, side airbags and head airbags. According to BYD Austria, six airbags are standard. The exact number depends on the market and trim level.
According to BYD and the Austrian motoring club ÖAMTC, the standard equipment includes the driver and front passenger airbags, side airbags for the front seats and curtain airbags. The front passenger airbag can be switched off when a rear-facing child seat is installed on the front passenger seat.
If the airbag system develops a fault, first have the fault memory read out. Disconnecting the battery and removing the control unit should be left to a specialist workshop. Then create a repair order online and send the unit to Airbag24.
Processing usually takes 3–4 working days: Airbag24 checks, repairs and tests the unit. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
