  1. Cloggy MAF sensor 2.0 JTDm -12

    Alfa Giulietta
    Ciao tutti! Noticed that the MAF sensor (between airbox and turbo) is really cloggy with oily dirt at the connections to the inlet. See attached photo. Where is that coming from? Airfilter is dry and clean. Is it blowing oilmist backwards from turbo?? Is this normal and standard to clean it now...
