Ok, so I have a friend trading in a 09 335 X-Drive e92 with coral red interior so we decided to trade my black for his, my car is a 2008 e92 335i both cars had sport package his had iDrive mine does not.

This whole swap was very easy and was rather painless except this issue, everything in my car works flawlessly and his is now throwing an air bag light for the passenger side (pic below). There is only one thing on his car a white clip under both seats that mine didn't have but its unhooked on both sides and its only throwing an air bag light for the passenger side.

Any help greatly appreciated! Thanks.



Clip under seat

You've switched active head restraint seats in the '09 with non-active head restraint seats. This might be why. When I was switching bumpers from m-tech to original I got weird errors as I changed just one fog light plug at a time.

Omg! I bet that's what it is! Hmmm why would it only throw the passenger side though

When I just changed the connector for the left side. I decided to see if I did it right and turned on the car. (You should get a bulb out message for the right.) I got a few messages, not just a bulb out. I wouldn't be surprised if it is something similar. Once I fixed the right, all the messages disappeared.
