    Hello. I am a fellow W168 MB A Class owner from Italy. I recently had
    to deal with the MB policy regarding a specific repair over the car.
    It appears that a vital sensor for the correct operation of the car,
    the MAFS, is not replaceable directly but if found faulty MB policy is
    to replace the entire ECU. That's because unbelievably and unlike all
    modern vehicles the sensor which is a part subject to ruin over time
    and eventually die is soldered directly to the ECU logic board.
    The MAFS which has a specific part number and was produced by Temic
    (Continental) is made unavailable as a single spare part in the
    MB repair would cost 1600 euros to the owner over a damage of a piece
    which should cost 150 euros circa.
    Also note that if one decides to go on and replace the ecu after some
    time the new MAFS could die again leading to the need to replace the
    ECU again as per MB policy. This means at some point people will be forced to
    dump their w168 as a repeated 1600 euros repair over time makes no
    sense on cars which lost their market resale value.
    I created a petition online to ask both Mercedes Benz and Continental
    to change their policy on this particular matter.
    Here's the link A Class W168 MAFS replacement unit Petition
    If you are with me please go ahead and sign it.


    P.S. I know there are services to repair and test the MAFS but that's not the point.
