DS5 Airbag Warning Light

I had a similar issue with my DS5. That airbag light is a pain. Usually, when it comes on intermittently like that, it signals a problem with the restraint system. Have you scanned the car for error codes? That would be the best first step to isolate which airbag sensor is causing the problem.

Yes, I did scan the car. The error code pointed towards a general airbag system failure, which wasn't super helpful in narrowing things down. Did your error code give you any more specific information?

Yes, I had a similar vague error. From my experience, and knowing the system architecture, it's more than likely a loose plug connection. Given the potential safety implications of a faulty airbag system, I strongly suggest taking it to a workshop to have them properly diagnose and repair the affected cable or plug connection.

Appreciate the advice. I took it into the shop this morning, and you were spot on. They found a defective connector, exactly as you suggested. Cost me 95€ to get it sorted. Thanks for the help!
