A flick of the ignition and it will start. I didn't realize this consciously until I drove my family's older Hondas. A flick of the ignition there wasn't anywhere near as productive....
I used to prime up the fuel pump on my 1967 912, but that wasn't a voluntary thing.
On the BMW, you will hear the fuel pump priming when you unlock the doors, so it is doing it without you knowing.
I would guess that it is linked to when it senses the key in the proximity of the car, not triggered by the actual act of unlocking.
So that would mean every time you walk near the car with the key in your pocket the fuel pump will prime itself? I could see it being triggered by unlocking the doors, but not being near it. I must walk past at least two of my vehicles with keys in my pocket a dozen times a day, never entering or driving them.
I don't lock my car at home when it is in the garage. I guess you responded to my post before I finished elaborating on it...touching the door handle is what triggers a response to being near it, from what I can recall.
