Citroën ë-C3 airbag control unit repair⁽¹⁾

What should you know about Citroën ë-C3 airbag control units?

The airbag control unit in the Citroën ë-C3 evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire airbag system. If it detects a fault, the airbag warning light comes on. Airbag24 repairs a defective control unit of this model by mail-in service.

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. During the repair, the crash data is erased and the unit is then checked for correct function.

The airbag system is safety-critical, so please leave any work on it to a qualified workshop. The repair takes place in our workshop in Berlin; the unit is then sent back to you.

Which Citroën ë-C3 generations are there?

The Citroën ë-C3 belongs to generation IV, which has been built since 2024. Production is ongoing.

Generation IV is the current series of this electric car. Equipment and software can differ between versions within a series, so a control unit should always be matched using its part number and the vehicle data. For the assignment, the series matters, not the model year alone.

• IV (since 2024, production ongoing) – current series of the electric Citroën ë-C3

How do I identify my Citroën ë-C3 airbag control unit?

The part number on the label of the control unit determines the exact version. Together with the model year and equipment of your vehicle, it allows the correct unit to be identified.

The part number is the most important clue. Note it down before you send the unit in, so that the assignment is clear. The model year and the vehicle identification number (VIN) of your Citroën ë-C3 also help. You will find both in the vehicle documents.

Examples of fault codes that can occur with this model are F620, F00F and B0001. A single fault code does not prove a defect on its own; only an inspection shows whether the control unit is affected.

What airbag equipment does the Citroën ë-C3 have?

Standard equipment on the Citroën ë-C3 includes driver and front passenger airbags, two front side airbags and head airbags at the front and rear. The exact equipment depends on the trim level.

The vehicle therefore has several airbag modules that the control unit must monitor. The equipment of your vehicle is listed in its vehicle documents.

The route to repair runs as follows:

• Have the fault memory read out.
• Have the battery disconnected and the control unit removed by a qualified workshop.
• Create a repair order online.
• Send the control unit to Airbag24.

Processing usually takes 3–4 working days, during which we check, repair and test the unit. The repaired control unit returns with all vehicle data and is ready for use as soon as it is refitted — coding or programming is not necessary.
