Airbag control unit with part number 98 237 413 80

What is the function of Airbag Control Unit 98 237 413 80?

The airbag control unit with part number 98 237 413 80 is the central control unit (SRS ECU) for the passive safety system in the Peugeot 2008 II. As an original OEM part from PSA (Peugeot/Citroën), it is responsible for monitoring and activating all components of the Supplemental Restraint System.

The primary task of this control unit is to process signals from crash sensors distributed throughout the vehicle in real time. In the event of a collision, it determines within milliseconds which restraint systems—such as front, side, or head airbags, as well as seatbelt pretensioners—must be deployed to provide optimal protection for occupants.

A key feature of control unit 98 237 413 80 is its permanent storage of so‑called crash data after deployment. This data locks the unit and prevents further use until professional repair is performed. This lock serves as a safety measure to mandate a thorough inspection of the entire system.

Why does control unit 98 237 413 80 fail?

The most common cause of failure for control unit 98 237 413 80 is the retention of crash data following an accident. Additionally, internal electronic faults—such as defective components or broken circuit traces—can impair functionality and necessitate repair.

After an airbag deployment, the control unit is permanently locked. This lock cannot be cleared using standard diagnostic tools at a workshop. The crash record stored in the internal memory prevents reactivation of the system and results in a continuously illuminated airbag warning light.

Even without an accident, purely electronic faults may occur. These include defective components on the circuit board, broken solder joints, or internal communication errors (CAN bus errors). In similar systems, such defects trigger error codes like 93F9 or 65535, indicating an internal control unit malfunction.

Before removing the control unit, a careful inspection at a specialized workshop is essential. Defects in external wiring, loose connectors, or issues with the sensors themselves must be ruled out to avoid misdiagnosis.

How do you recognize a fault in Airbag Control Unit 98 237 413 80?

A fault in Airbag Control Unit 98 237 413 80 primarily manifests as a persistently illuminated airbag warning light on the instrument cluster. Often, the control unit also becomes inaccessible via diagnostics, making precise fault analysis at the workshop impossible.

The most obvious symptom is the constantly lit airbag warning light. It does not extinguish after starting the vehicle, signaling a serious issue within the safety system that compromises airbag functionality.

Another clear indication is the lack of communication. When a workshop attempts to read the fault memory, the diagnostic tool cannot establish a connection with the airbag control unit. The unit fails to respond to requests and disappears from the system display.

As a result of the fault, all safety functions controlled by the unit are disabled. This means that in the event of another collision, airbags and seatbelt pretensioners would no longer deploy, posing a significant safety risk.

In which vehicles is control unit 98 237 413 80 installed?

The airbag control unit with part number 98 237 413 80 was specifically developed for the second generation of the Peugeot 2008. It is used in both pre-facelift models and the revised versions. At Airbag24, we repair this control unit for the following specific models:

Peugeot 2008 II (model years 2020–2023)

Peugeot 2008 II Facelift (from model year 2023 onward)

What are the advantages of repairing 98 237 413 80?

Repairing the original airbag control unit offers significant benefits compared to purchasing a new one. The most critical factor is substantial cost savings—often exceeding 70%. Additionally, there is no need for time-consuming reprogramming, as the vehicle-specific original part remains intact.

A new control unit with part number 98 237 413 80 typically costs between 750 and 800 euros from the manufacturer. Repair, by contrast, is a far more economical solution that restores full functionality at a fraction of the new‑unit price.

Since the original control unit, coded to the vehicle’s chassis number, is repaired, no reprogramming or coding is required at an authorized dealer after installation. The unit can simply be reinstalled (plug-and-play) and immediately functions as intended.

A professionally performed repair fully restores the original safety and reliability of the control unit. You also receive a 12-month warranty on all work carried out.

How does the repair process at Airbag24 work?

The repair process at Airbag24 is designed for maximum efficiency and safety. After you send in the removed control unit, a detailed diagnosis is conducted, followed by professional refurbishment, during which crash data is erased and defective components are replaced. A final test ensures full functionality.

Upon receipt of your control unit, our technicians perform a comprehensive analysis to pinpoint the exact cause of the fault—whether it’s solely a crash-data entry or an additional electronic defect on the circuit board.

In the next step, the stored crash data is securely and completely erased from the control unit’s memory using specialized equipment. If hardware defects are identified during diagnostics, the affected electronic components are expertly replaced at the component level.

Subsequently, the repaired control unit undergoes an intensive functional test on our test benches. All inputs and outputs are simulated to verify proper operation under real-world conditions. Following a successful test, the device is prepared for return shipment.

What shipping options are available?

At Airbag24, you can conveniently and flexibly send in your defective control unit. You have the choice of either shipping the package yourself free of charge or arranging a convenient UPS pickup. For return shipping, we offer free standard and fast express options, including cash-on-delivery.

For the outbound shipment, you can either send the control unit to us at your own expense or book a comfortable UPS pickup from your preferred location.

For returning the repaired unit, several options are available: free UPS standard shipping, fast UPS express shipping, UPS standard shipping with cash-on-delivery, and UPS express shipping with cash-on-delivery. Alternatively, personal collection at our premises is also possible.
