Nick I think all of them will be 12V. My theory is BMW have connected 9 LEDs in series to make them take the 12V load. Thats the reason why you have 18 LEDs in the turn light. Also explains why they 'suddenly' choose to put 4 LEDs on the sides of the taillights because 5 are for the Light rods.

My measurment is far from my thoughts but it's logical because turn LEDs are double (in SMD units) than the tail LEDs.
So I found 230-240mA on turn lights and 120-130 on tails, which I think prooves that they are 12V
The question is: will it be much brighter if they get 12V constantly? I don't think so

I think they will. But Nick even if they can where will you connect the bars, you have no 12V sources in normal usage. However your tests have just shown that the LEDs won't blow when you hits the brakes!!
That's what I mean, so there is no reason to change the diagram.
except if we like better to have the brake at the center and the tails (+brake force) at the corners

Nick do you have access to some Switching diodes that will switch at a voltage above about 7-9 volts? Then you can put those in the path of the tail and brake lights. That way they'll be off on normal usage but will come on when you press or hit the brakes.

I meant to switch the background bulbs behind the LED rods off in normal usage but to make them come only when you brake i.e. when they receive +12V and remain off when they are receiving +6V.

That way we must use also resistors, otherwise we will have faults from light module.

Can anyone think of a good electronic circuit that will act as a switch that will only close once voltage goes over +6V. I thought a solution but that uses a Relay but that will mean atleast a 10ms delay in the bright light appearing.
