From the first phone call, the order processing, to the shipping everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red light for the airbag). Today the message came from SWE, the car is running again, the red light is off and the HU was also passed. Once again many thanks for the help in need. Keep it up and maybe word will also spread in SWE that Airbag 24 does great work. Regards Gerd

What is a Mercedes-Benz E-Class C238 Coupé airbag control unit?
The Mercedes-Benz E-Class C238 Coupé airbag control unit is your vehicle's central safety unit, continuously analyzing sensor data and precisely deploying the airbags and seatbelt pretensioners in the event of an accident. It also stores important crash information and is crucial for the comprehensive occupant safety of your coupé.
This state-of-the-art control unit is specifically designed for the C238 series (model years 2016–2023).
It monitors all passive safety systems and ensures that airbags such as driver, passenger, knee or side airbags are immediately activated in an emergency.
A special feature is the integration into the 48-volt electrical system, which is immediately deactivated for safety reasons after an airbag is deployed.
The control unit communicates continuously with the vehicle diagnostic system to detect errors at an early stage.
Why is the Mercedes-Benz E-Class C238 Coupé airbag control unit defective?
A Mercedes-Benz E-Class C238 Coupé airbag control unit often fails due to internal damage, power surges, or crash data stored after an accident. These can block the unit or cause system failures, making a specialized Mercedes-Benz E-Class C238 Coupé airbag control unit repair essential to ensure occupant safety.
Internal errors in the control unit can occur due to aging of the components or electrical faults.
This often leads to a sudden failure of the airbag function, signaled by an illuminated SRS warning light in the instrument cluster.
Another common reason is storing crash data after an accident, even if the airbags were not deployed.
This data blocks the control unit and prevents it from being reactivated without professional repair or data deletion.
Communication errors with other vehicle systems or a faulty power supply can also cause the device to stop functioning and be diagnosed as broken.
Common error codes for Mercedes-Benz E-Class C238 Coupé airbag control unit repair
When repairing the Mercedes-Benz E-Class C238 Coupé airbag control unit, specific error codes are crucial for identifying the exact cause of a defect. These codes directly indicate problems within the control unit itself, from communication errors to internal defects or stored accident information, enabling a targeted diagnosis.
- B1000: Control Unit Communication Error → Indicates that the airbag control unit cannot establish a proper connection to other vehicle systems. This requires a diagnosis of the communication lines or the control unit itself.
- B1003: Control Unit Faulty → This code indicates a general internal error in the airbag control unit, often requiring replacement or repair. It is a clear indication of a failure of the internal hardware or software.
- B119C: Control Unit Internal Fault → Indicates a more specific internal defect within the airbag control unit's electronics that impairs functionality. In-depth analysis by a workshop is essential.
- B1600: SRS System Error, Airbag Control Unit Problem → This trouble code indicates a problem within the SRS system that is directly related to the airbag control unit. It requires immediate Mercedes-Benz E-Class C238 Coupé airbag control unit repair.
- B2D8A: Airbag control unit defective → A direct indication of a defect in the airbag control unit, often resulting from internal component failure. This problem can only be resolved through specialized repair.
- B2D92: Airbag control unit fault (control unit N2/7) → Specific code for a fault in the airbag control unit N2/7, indicating a hardware or software malfunction. This requires a precise fault diagnosis for repair.
- B1C3200: SRS control unit has detected an impact (crash data stored) → This code indicates that the control unit has detected an impact and stored crash data. After an accident, a reset or repair of the control unit is mandatory to restore its functionality.
What part numbers are available for the Mercedes-Benz E-Class C238 Coupé airbag control unit repair?
For a successful Mercedes-Benz E-Class C238 Coupé airbag control unit repair, exact OEM part numbers are essential to ensure compatibility and safety.

The first and most common original part number is A2389008100, which is explicitly listed for the airbag control unit of the Mercedes E-Class Coupé C238 E 300 (engine code M274.920).
This number offers the highest accuracy and has been validated by independent sources.
Another confirmed original part number relevant to the C238 Coupé airbag control unit is A2139003617.
Both numbers are directly from Mercedes-Benz and guarantee full compatibility with your vehicle.
