Interior Access/Start Authorization Antenna 1 (R138)
 

Does anyone know where that antenna is? I think it's center console, but don't have a copy of alldata.

For future reference: the antenna is attached to the bottom of the MMI panel in the center console, small 2 wire connector goes into it. The tricky part is the other end of that wire pops back up near the rear/back seat end of the center console body and that connector goes into a female socket that's hidden under the carpet. If you don't plug that in, you'll get the fault in the original post.
