Peugeot 607 Airbag Warning Light

I had a similar problem with my 607. Did you inspect the cable and plug connections? A defective connection is a plausible culprit.

When you mention 'cable and plug connections', could you be more specific? Are there particular points within the airbag system that are more prone to failure or corrosion?

In my case, the issue was a loose connection beneath the driver's seat. Given the safety implications, I'd advise against extensive DIY repairs. A diagnostic check at a qualified workshop is prudent.

I took it to a mechanic, and the diagnostic check confirmed a defective connection. The repair cost 95€, including labor. The airbag warning lamp is now off. Thanks again.
