2006 E53 x5 4.4L

Hello,

Odd problem with the 4.4L x5. Keeps throwing an error saying my o2 sensors are backwards and it’s driving me nuts. I even out all 4 new sensors in and still does it. I believe it’s the upstream 2 it thinks are backwards (there not the wire wouldn’t even stretch if I wanted to). Thoughts? Love this suv. Drove it 5000 miles and worked perfect till it started running rough one day.
