Xpeng P7+ airbag control unit repair⁽¹⁾

What should I pay attention to with Xpeng P7+ airbag control units?

The Xpeng P7+ airbag control unit evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire restraint system. If it detects a fault, the airbag warning light comes on. Airbag24 repairs the control unit you send in from your own vehicle.

After an accident, the control unit stores crash data and locks itself. A defective control unit can impair the function of the entire airbag system. Whether a unit can be repaired is determined by the examination after it arrives.

The airbag system is safety-critical, so leave any work on it to a qualified workshop. If the airbag warning light is on, have the system checked promptly, as a defective airbag system may not deploy as intended in an emergency.

Which Xpeng P7+ generations are there?

The Xpeng P7+ belongs to the P7+ model series. This series has been built since 2026 and is still in production. To assign your control unit, the build year and part number count, not the model name alone.

• P7+ (since 2026) – current model series, still in production

Equipment within the series can vary by market and trim level. Check the build year and equipment of your vehicle before you send in a control unit.

How do I identify my Xpeng P7+ 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 important. With these details, the matching control unit can be identified.

The part number is found on the removed control unit. The build year and the vehicle identification number (VIN) are listed in your vehicle registration documents.

The control unit may store fault codes such as U0151 (communication with the airbag control unit lost), B16201B (resistance too high in the front driver airbag firing circuit) or B0001 (firing circuit control of the driver airbag, stage 1, disturbed). A single code does not prove a defect in the control unit; the examination determines the cause.

What airbag equipment does the Xpeng P7+ have?

According to available equipment information, the Xpeng P7+ has several airbags, and seven is commonly cited. These include front, side, curtain and centre airbags. Which of them are fitted to your vehicle depends on market and trim level and is set out in the owner's manual.

The control unit drives the firing circuits of the airbags, monitors the sensors and coordinates deployment in a collision.

The route to repair: have the fault memory read out. A qualified workshop then disconnects the battery and removes the control unit. Next, create a repair order online and send in the control unit. Processing usually takes 3–4 working days: checking, repairing and testing.

The repaired control unit comes back with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is needed.
