That's how I recall the 330d, never tried it with the engine off.
Wish the 535i had the PTC heater, it is the only negative about the car. Miss the fact the 330d diesel, like your car, would start giving cabin heat almost immediately.
Now when I get to the next village (3-miles) and ECT is about 53 - 55C (similar to the diesel at around freezing temperatures) I'm no where near at the same cabin heating. It is just warm, where the 330d would be pumping out loads of heat and even adjusting the face vent temperature back to cooler levels.
