Xpeng G9 airbag control unit repair⁽¹⁾

What should be considered with Xpeng G9 airbag control units?

The airbag control unit in the Xpeng G9 evaluates the crash sensors, triggers the airbags and seat belt tensioners, and monitors the entire airbag system. If it detects a fault, the airbag warning light in the instrument cluster lights up. Airbag24 repairs the control unit that is sent in.

After an accident, the control unit stores crash data and locks itself. Airbag24 deletes the crash data and repairs the device sent in; the cause of a fault is only established by an inspection at a specialist workshop.

The airbag system is safety-relevant. Work on it should therefore be left to a specialist workshop.

Which Xpeng G9 generations are there?

The Xpeng G9 is one model series with the code G9. It has been built since 2023 and production is still ongoing.

The Xpeng G9 was introduced for the European market and later revised. The exterior stayed the same, while the interior received comfort improvements.

• G9 (since 2023): model series for the European market, production still ongoing.

The design of the control unit can differ depending on market and equipment.

How do I identify my Xpeng G9 airbag control unit?

The part number on the control unit's label determines the exact version. The model year and the equipment of the vehicle are also important for assigning the correct control unit.

A fault code is an indication, but on its own it does not prove a defect. Examples from the fault list for the Xpeng G9 are U0151 (communication with the airbag control unit lost), B16201B (resistance too high in the front driver airbag firing circuit) and B0001 (firing circuit control of the driver airbag stage 1 disturbed).

Only reading out the fault memory and an inspection by a specialist workshop show whether and where a fault exists.

What airbag equipment does the Xpeng G9 have?

The Xpeng G9 has an extensive airbag system with front, side and head airbags. The number and arrangement depend on the equipment level and the market.

In a European safety assessment (NCAP), the G9 that was tested was documented with front, side and head airbags in all three rows, front side chest airbags and a centre airbag on the driver's side. Knee and pelvis airbags are not included in this assessment.

The details come from this assessment and may differ by market. Check the model year and equipment of your vehicle before sending in a control unit.

The Xpeng G9 airbag control unit repair works by mail-in. First, a specialist workshop reads out the fault memory. Before removal, it disconnects the battery; the control unit should also be removed by a specialist. Then create a repair order online and send the removed control unit, well packed, to Airbag24.

Processing usually takes 3–4 working days (checking, repairing, testing). The repaired control unit returns with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
