Difference between diversity antennas?

[Jonas007]

Hello there, so I have an E91 wagon and the circuit board "diversity antenna" died. It's in the rear spoiler thing on the wagon, and the horrible design BMW did just let water constantly get in there until the corrosion destroyed the board.

I've found one online to replace it for $229 which isn't terrible, but this board should be worth about $10 considering the components and resistors on it.

My question is about the part for the sedan working interchangeably. I'm not certain as I haven't seen a photo, but from the diagram it looks like the connectors are the same. The wreckers have ZERO wagons across all of Canada, while there are plenty of 325/330 E90 sedans that have this type of board. The part number is different, but I would also question why BMW designed two separate parts considering they have the identical function.

Sooooo, all that said, doesn't anyone know if these are interchangeable?

For reference the sedan one is in the back of the middle of the headliner by the rear windshield.

Do you have any wiring diagrams or pictures of the parts?

No diagrams, that's what I'm trying to get. I could of course take a photo of the board from my wagon, but without a photo of the sedan board to compare to, it wouldn't help much I don't think.

I may have solved my own problem here...looks like some of the connectors are in different spots from one board to the other, and even the connector types are different. One of the flat ribbon cables from the e91 looks to be round on the e90...too much hassle to extend the cables and change them:
