Works like a charm!
Everything went perfectly, I can only recommend it.

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

Everything worked out great! Read out fault memory, sent it in, received offer and sent in the defective control unit. Got it back repaired after 3 days, price exactly as in the offer. It can't get any better 👍

What is a Mercedes-Benz CLA-Class C117 Saloon airbag control unit?
The Mercedes-Benz CLA-Class C117 Saloon airbag control unit is the central safety unit in the passive occupant protection system, which activates all restraint systems in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the proper function and deployment of all airbag modules and belt tensioners in the vehicle.
This electronic module is crucial for your safety and reacts instantly to collision signals. It is typically installed in the center console and connected to the sensors via wiring harnesses.
Proper functioning of the airbag control unit is essential for the operational safety of your Mercedes-Benz CLA-Class C117 Saloon. If a fault occurs, the airbag warning light will illuminate continuously.
Why is the Mercedes-Benz CLA-Class C117 Saloon airbag control unit defective?
The Mercedes-Benz CLA-Class C117 Saloon airbag control unit often fails because it stores crash data after an accident, preventing it from being used again. Internal electronic errors or a malfunction due to aging or voltage spikes can also lead to a defect that renders the airbag systems unusable.
A common cause of the defect is the deployment of the airbags in an accident. Crash data is permanently stored in the control unit.
This storage prevents reuse of the module without a professional Mercedes-Benz CLA-Class C117 Saloon airbag control unit repair. Internal component failures or software errors may also be present.
Signs of a defect include a persistent airbag warning light or the inability to clear error codes. The control unit often no longer communicates correctly with other vehicle systems.

- B220700 → Internal error in the “Supplemental Restraint System” control unit → Control unit is defective or blocked by crash data.
- B1000 → Control unit communication error → The airbag control unit can no longer communicate with other vehicle components.
- B2000ff / B2001ff (generic) → Internal malfunction of the control unit → Various internal problems in the airbag module itself that require a Mercedes-Benz CLA-Class C117 Saloon airbag control unit repair.
