Peugeot 307 Airbag Warning Light

I had a similar problem with my 307. It could be a faulty connection in the airbag system. Have you tried wiggling the cables and plugs under the seats? Sometimes that can temporarily fix it, indicating a bad connection.

Thanks for the suggestion. Which cables under the seats are you referring to specifically?

There are a few, but the ones connected to the seat airbags and seatbelt pretensioners are the most likely culprits. However, I would recommend taking it to a workshop as it may be related to the airbag control unit.

Thanks. I took it to a workshop, and it was a defective cable connection like you said. They repaired it for 95€. Everything is working fine now.
