Airbag control unit with part number 9807568180

What is the function of the airbag control unit 9807568180?

The airbag control unit with part number 9807568180 is the central control module for the occupant protection system in vehicles such as the Peugeot 308 and Citroën C4 Picasso II. It processes signals from crash sensors and determines whether and when airbags and seatbelt pretensioners should be deployed to protect occupants during a collision.

As an original OEM component, often referred to as a crash sensor, it continuously collects data from acceleration and yaw rate sensors throughout the vehicle. Upon detecting a collision, it activates the appropriate restraint systems within milliseconds.

The proper functioning of this control unit is critical for the vehicle’s passive safety and passenger protection.

Why does the control unit 9807568180 fail?

The most common cause of failure for the control unit 9807568180 is the storage of crash data after a collision. Even in minor impacts where only the seatbelt pretensioners deploy, the unit becomes internally locked, preventing further operation and triggering the airbag warning light. Internal hardware defects can also be a contributing factor.

This lockout is a manufacturer‑imposed safety feature. The crash data stored in its memory blocks communication with diagnostic tools and prevents simple clearing of the fault memory via the OBD2 interface.

Such an internal fault is often logged as an unerasable error code in the system. The component is also compatible with the alternative part number 624926000, which may exhibit similar fault symptoms.

How do you recognize a defect in the 9807568180?

A defective airbag control unit 9807568180 typically manifests as a permanently illuminated airbag warning light on the instrument cluster. Another clear indication is that workshops’ diagnostic tools can no longer establish communication with the control unit to read or clear fault codes.

The warning light illuminates immediately upon turning the ignition on or while driving and does not extinguish, signaling a critical fault in the restraint system.

In some cases, the engine check light may also flash, accompanied by an error message indicating an internal fault in the airbag system. Even without visible airbag deployment—such as activation of seatbelt pretensioners alone—crash data is still recorded, triggering these symptoms.

In which vehicles is the 9807568180 installed?

The airbag control unit 9807568180 is primarily used in various Peugeot models, especially the 308 series. It is also found in certain Citroën vehicles. At Airbag24, we have experience repairing this control unit for a range of PSA Group vehicles.

At Airbag24, we repair part number 9807568180 for the following specific models:

Peugeot: 308 II (model years 2013–2017), 308 II Facelift (2017–2021), e-308 III, 308 SW II (2013–2017), and 308 SW II Facelift (2017–2021).

How is the 9807568180 professionally repaired?

Upon receipt at Airbag24, the control unit 9807568180 undergoes a standardized repair process. This begins with an incoming inspection to precisely diagnose the fault. Next, stored crash data is erased, and any defective electronic components are replaced. A final functional test ensures full operability before the unit is returned with 2 years' statutory liability for defects.

First, a comprehensive electronic diagnosis is performed to identify all potential sources of failure on the circuit board, such as short circuits or other damaged components. A purely software‑based solution is often insufficient.

The core of the repair involves erasing persistent crash data and replacing damaged parts. This procedure requires specialized equipment and is usually beyond the scope of standard workshop diagnostics.

Following successful restoration and calibration, compatibility with the vehicle is verified. The repaired unit is then fully operational again and can be installed in the vehicle without additional programming (plug-and-play).

What are the advantages of repair over purchasing a new unit?

Repairing the original airbag control unit 9807568180 is an economically and technically sensible alternative to costly new purchases. You save significantly, as a new unit often costs over €500. Additionally, there is no need for time‑consuming re‑coding, reducing both time and further workshop expenses.

A key advantage is the substantial cost savings—often exceeding 50% compared to the price of a new part. You regain full functionality at a fraction of the cost.

Since the original control unit is repaired, all vehicle-specific data and coding remain intact. After repair, the unit can be easily reinstalled and will function perfectly right away.

With a professional repair, you choose a sustainable solution and receive 2 years' statutory liability for defects on the work performed, ensuring TÜV‑compliant and safe operation of the restraint system.
