While driving a Porsche 911 (997), the airbag warning light came on. I thought the part was the cause, so I bought a replacement and took it to the dealer. They found no problem with this part, but instead, an issue with the passenger seatbelt sensor. This is the part I removed, just in case. It was fully functional until the removal. I found that these sell for around 30,000 yen each on eBay. The part number is 997 618 223. This is a set of 2 (left and right). - Model Number: 997 618 223 - Color: Blue - Type: Sensor Thank you for looking.
