Yes, air flow meter. I have always referred to the type with a flap a VAM and a type with a sample tube a AFM. The 190D turbo is different. The meter is actually mounted to the air filter housing lid. There is a rectangular hole where it mounts to the housing and a round hole where the hose mounts. I can get some pics.
