Capacitor stores excess power and distributes as needed from the source requesting it. Issue with BMW when switching to HID's is the HID bulb requires much less power to light than a typical halogen bulb. With less power needed our computer detects that it is consuming less than normal power and it throws an error code and also sends pulses repeatedly to ensure it is accurate as being bulb out situation (hence the flickering members speak of). Well when you add a capacitor it stores the excess power tricking the computer into thinking it is a normal situation and sends only amount needed for HID ballast to function in turn eliminating the error and pulse situation
