    All MAF sensors have 5 pins... the 5th pin is for an air temp sensor which isn't fitted to A3's etc... RS4 uses this (and maybe a couple of others) but not A3/S3 etc..

    You can check if you have the right sensor by the number on the sensor itself (of course you need to special security torx bit to remove it)

    All wideband cars like your AUM with have a sensor with 049 on the end like the middle one in this pic...
