Airbag control unit with part number 9674291480

What is the function of the airbag control unit 9674291480?

The airbag control unit with part number 9674291480 is the central control module for the occupant protection system in various Peugeot models. It processes data from crash sensors and determines whether airbags and seatbelt pretensioners should be deployed in the event of a collision, thereby providing optimal protection for vehicle occupants.

As an OEM replacement part (Original Equipment Manufacturer), this module is precisely matched to the vehicle architecture of models such as the Peugeot 308 or 3008. It processes signals from acceleration and pressure sensors within milliseconds and, in an emergency, activates the pyrotechnic charges of the corresponding restraint systems. Therefore, flawless functionality is crucial for vehicle safety.

Why does the airbag control unit 9674291480 fail?

The most common cause of failure for control unit 9674291480 is the storage of crash data after an accident, even in minor collisions. Additionally, internal electronic defects in components on the circuit board or communication malfunctions may occur, making repair unavoidable and triggering the airbag warning light.

After an accident where, for example, only the seatbelt pretensioners were activated, the control unit locks further operation for safety reasons. This condition is recorded in the fault memory as “crash data stored” and cannot be resolved simply by clearing it via a diagnostic tool; the electronics themselves must be reset.

Another reason is purely electronic faults. These can include defective components on the circuit board or issues with the internal memory. In such cases, component-level repair is the most cost-effective solution.

It’s important to note that there are related or interchangeable part numbers, including 9665100080, 610714900, 619763800, 9673383480, and 9675181780, which are often installed alongside Bosch code 0285010830 in the Peugeot 3008 I.

How do you recognize a defect in control unit 9674291480?

A defect in control unit 9674291480 primarily manifests as the airbag warning light remaining constantly illuminated in the instrument cluster. Often, communication with the diagnostic tool is also lost, or internal, non‑erasable error codes are stored. In some cases, the engine check light may additionally flash.

The most obvious symptom is the persistently lit airbag warning light. It does not turn off after starting the engine, indicating a serious fault in the restraint system and resulting in a significant deficiency during the main inspection.

Another clear sign is when the workshop’s diagnostic tool cannot establish communication with the airbag control unit. The module fails to respond to requests, suggesting a complete failure of the communication electronics.

Error codes such as “Internal control unit error” or “Crash data stored” are frequently read out. These errors cannot be cleared using standard workshop testers and require specialized hardware repair.

In which vehicles is part number 9674291480 installed?

The airbag control unit 9674291480 is mainly used in various Peugeot models, particularly the first-generation Peugeot 308, the first-generation Peugeot 3008, and the station wagon variants—308 SW of the first and third generations. A precise verification of the part number is essential.

At Airbag24, we repair the control unit with part number 9674291480 for the following Peugeot models:

Peugeot 308 I (model years 2007–2015, including facelift)

Peugeot 3008 I (model years 2009–2016, including facelift)

Peugeot 308 SW I (model years 2007–2015, including facelift)

Peugeot 308 SW III (model years 2021–2025, with facelift starting in 2025)

An important technical note: For the successor model, Peugeot 3008 II, other part numbers such as 9824811680 or 1658663080 are listed as compatible. The control unit described here is not intended for this generation.

What are the advantages of repairing 9674291480?

Repairing the airbag control unit 9674291480 offers substantial cost savings of up to 80% compared to purchasing an expensive new unit, which typically costs between 500 and 1,000 euros. A repaired unit functions just like a new one, requires no complex re‑coding, and comes with 2 years’ statutory liability for defects.

Targeted refurbishment preserves the vehicle’s original configuration. This means the repaired control unit can be reinstalled without requiring additional programming or recalibration (plug-and-play), saving both time and money at the workshop.

Moreover, repair is a sustainable solution. Rather than discarding a complex electronic component, it is professionally overhauled and restored to full functionality. Of course, every repair comes with 2 years' statutory liability for defects.

How does the repair process work at Airbag24?

The repair process at Airbag24 is designed for maximum safety and efficiency. After removing and sending in control unit 9674291480, our technicians perform a thorough diagnosis, fix the electronic fault, reliably erase all stored crash data, and replace any defective components. Each repair is completed with 2 years' statutory liability for defects.

In the first step, the control unit is removed at a specialized workshop. We recommend having a precise diagnosis performed beforehand and attaching the shipment’s error log. Upon receipt at Airbag24, our specialists analyze the circuit board and memory chips.

This is followed by professional repair: defective components are replaced, and stored crash data is irreversibly erased at the hardware level. The control unit is thus returned to like-new condition. Final tests on our test benches ensure full functionality before the device is shipped back to you.
