S823 Hot-Climate Version

[Bobafixit]

Hi guys
I was just decoding a Australian Z3 3.0 Vin.
As well as the usual spec I noticed that the car has the following spec.

S823 Hot-Climate Version.

Does anyone know what this actually is and what parts etc it includes ?

It would be nice to know as I will be shipping my car from the UK to Australia in the near future, so it would be nice to know.
