E85 - Diversity Antenna Location

Thanks! So to access you go through to the boot or the wheel well?
In the boot, on the left, behind the carpet. The diversity antenna is part of the HiFi system, it doesn’t have anything to do with the keys.
I've read the module is also to transmit the signal for the remote central locking
To be fair, when I was researching the various stereo radio and antenna components in my Z4M in the past I got a bit confused too because according to various places on the internet some other BMW models like the E61 have another "diversity" in the roof that does seem to have something to do with key fobs and central locking.
For example:
I find the name "diversity" confusing to begin with but to then call 2 units with different jobs the same thing, a "diversity", can be a bit confusing.
@SPARTON , As far as I understand it the Z4 and Z4M (unlike some other models) do not have this "diversity" for key fobs. The only "diversity" they have, as described by others here is a component of the stereo head unit antenna system and it lives in the boot. If you have a problem with key fobs I'm not sure this component would be the right place to start investigation.

Incorrect. I located the Diversity Antenna, brought a new one from eBay, swapped out - and Bingo! The remote central locking is now working.
Incorrect - it's the diversity antenna in the boot
What I wrote (cut and paste) is directly out of the BMW E85 service manual.

I stand corrected, although I am very surprised. Nothing that I could find in NewTIS (functional descriptions, wiring diagrams) supports this.
