    mass air flow issue

    Hi folks, my esp light has come on and vagcom won't clear the fault !
    It's a 2002 s3 8l (recently put a 06 bam engine in on amk ecu) vagcom fault code is coming up with : 16486 - mass air flow sensor (G70) signal too low P0102 -35-00
    Any ideas ? As I've only 12 or so month ago replaced the maf for a new genuine unit, anybody know what configuration of the wires/plug ? To church the voltage so-on ? Cheers

    Check your wiring, the plug might have broken plastics, it happened to mine!

    Yes for both. Although personally as soon as my maf is plugged in it cuts out, did the same with a brand new genuine bosch maf as well. Pretty stuck!

    Fault code is cleared before sticking the new maf on,start the car code comes back, clear the code, try and drive and as soon as the revs drop car cuts out.
    Sorry to the op if this is a hijack but hopefully it'll all be relevant

    Sorry folks only just seen this, been really busy. What I ideally want to know is what voltage should the maf plug be kicking out ? As I want to check the voltage first-to see if there's a break in the wire soon.
    If the voltage is fine then I will replace the maf.
    Nice one slowcoach 3, pleased for you, do you have a part no or description for the plug ?
