I have a 3.0D and it has the heater. No remote needed, it is accessed through the Menu on the NAV screen as the "Auxillary heater". I also read in the MANUAL that it comes on automatically when the temperature is low enough when the car is first started so you get warmed up before the engine is warm enough.

However, here in Sydney, Australia, it will NEVER get that cold for it to come on, or for me to use it.
