Hey, I'm going through the process of replacing my passenger seat occupancy sensor in my 2014 i3. Was getting the airbag warning lights with the pop-up every time I started the car, and also getting and intermittent seat belt chime warnings even if there wasn't a passenger or if the seatbelt was plugged in. After clearing codes, the seat occupancy mat has been the persistent code. So I bought the replacement sensor- it's embedded in the cushion assembly- so it's kind of a pain to replace. With the new sensor in, now the computer needs to be recoded to recognize it (that part I didn't realize when I started this). So just now diving into ISTA+ and should be trying to recode it next week when I get my cable. So I might be asking for help since I'm a total noob at the coding stuff. I'm familiar with Bimmerlink and Bimmercode- but they can't activate the new seat sensor.

Just wanted to follow up that I was able to activate the new sensor using ISTA+. It was actually pretty straightforward. So all together the part was $615 shipped and I had to buy the ENET cable for $30. Not sure how much the dealer would have charged to replace it, but I know their price for the cushion/sensor was over $700 for the part alone. For reference the part number is: 52-10-7-392-874 2014-2020 BMW Seat Cushion Pad

Thanks for the info. Im experiencing a similar issue on my 2015. Did I understand correctly that the "2-10-7-392-874 2014-2020 BMW Seat Cushion Pad" is the only part required for the sensor replacement?

Or, do you need to buy a new sensor AND a new pad?
