Had the error SRS Airbag Service urgent on my Volvo C30. At Volvo they could only determine that the error with code CFFF cannot be reset. Proposed solution 865 € for a new module, plus removal and installation and coding + VAT! Airbag24 informed perfectly in advance via chat. Sent it Monday, by Friday the module was repaired and back with me. After installation we still had to delete the error. After that the message is gone. Conclusion: cheap alternative if you can invest a bit of own effort for removal and installation and reset

At first sight I had no confidence. But I don't regret it. Repair ordered, calculator sent, within a few days I had the diagnosis and the payment order. As soon as the payment was made my calculator came back in perfect packaging, repaired, (and accompanied by Haribos). In short, very fast and efficient service. I recommend.

What is a Mercedes-Benz CLA C117 airbag control unit?

The Mercedes-Benz CLA C117 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.

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.

Why is the Mercedes-Benz CLA C117 airbag control unit defective?

This storage prevents reuse of the module without a professional Mercedes-Benz CLA C117 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.
