Usually it is a small separate power unit that can often be started by remote control, and thus heat up the car for 20 minutes before you get in it in the morning.

Definately worth a go for you Mickken as I seem to remember you only have a short drive to work in the morning. We have webasto pre-heaters on our trains, they save engine wear from cold and means the train's pretty much warmed up before taking them out on a running line.

There's also the BMW residual heating, which if on, will continue to push warm air into the car when you're parked up after a run.

I have used it on mine and not really noticed the difference. I suppose it makes the defrosting process slightly quicker once you get going but not that helpful.

how does this work?

i found this out by accident when i was waiting for the wife and had the ignition on and was amazed that warm air was still coming out after a hour of being parked up.

does it use fuel? or is there a 12v heater somewhere?

I think it just uses residual heat from the engine. Works well on mine, its lovelly when your waiting to pick people up and dont want the engine on. You can also set it when you have the ignition off, like when you fill up with fuel (if your a great wet lettuce like me anyway...)

I agree, I'm loving that residual heat button in this weather, makes such a difference stepping back into a nice warm car!

I don't know which versions of the cars have it.. I think it's more spec dependant than age related.

My E36 M3 had it.. though due to some dubious internal alarm sensors all it managed to do was set the alarm off shortly after it came on..
