    P1100 fault code on 118i E87 2005

    Exactly what does this code refer to? I have been told everything from the MAF sensor, to the O2 sensors. Please clarify for me so I can fix it.

    Google is your friend. Manifold Absolute Pressure (MAP) Sensor Malfunction (Open/Short). Check the wiring.

    Car 1 N46 2006 120i
    Car 2 N46 2006 320i both same problems..

    I have tried with no luck replaced MAF Air-box 4X O2 sensors Up & Down-steam , MAP sensor maniflod & Cleared all and seperatly the adaptations with INPA, still no luck! Codes come back.
    Check plugs & wiring back to ECU.

    I know the car has had CCV done, so would an air leak throw up codes like P1100?? if not done correctly or the CCV is broken?
    Anyone know specifically a BMW tech please not something you found on google. Please don't reply if your not a tech, or you know 100% by your own experience on this specific motor, thanks.

    What I have not done is an ECU rest or refresh, as I don't know how or know what software to do this with.
