    A long time ago, BMW used to do seperate PDF ETM manuals, but now there are all linked up in a software program.
    There used to be an open BMW website/server, but when BMW noticed the huge amounts of traffic, they passworded it...

    Wiring diagrams here, http://www.bmw-planet.com/diagrams/release/en/

    And yes the DDE(Engine ECU) does take readings from both these sensors to determine fuelling e.t.c.

    Great find, that's the program. It was meant to be used on the GT1,


    You can see the familiar grey large buttons for the touchscreen

    They'll be separate all the way to the ECU.
    Unplugging any sensor will usually cause some change in the running, and in your case, it will use a default emergency value for the boost pressure, i'd expect it to keep the boost pressure low in a case like that as it isn't able to spot overboost conditions.

    They are totally seperate, the ecu has separate inputs for the AFM, and boost pressure sensor.
    If one is failing, it will not affect the other.

    Nope, not exactly...
    There may be a problem with turbo pressure, but you can't differentiate between bad pressure and a good sensor, or bad sensor/good pressure with out checking out the sensor.
