I had 2 weeks ago the airbag error. Went to a garage and said to me that there was i problem with the buckle second row right side. Googled and found this video. Ordered the buckle and the socket, and fix it in 15 minutes. Thank you very much chief!
Cost me just €100 for the buckle + socket. ❤

Sorry, it's not related with this video. I recently opened my drive shaft tripod and lost the grease. And I don't know which one I need to refill. It's kind of mustard color and more fluid than expected. Ford c max mk2 2013 1.6 tdci thanks

Just normal cv grease mate

Where can I get the diagnostic device from? I have this error in my seat car.
