Replacement a pain because the upholstery needs to be removed from the seat to get to it. I have a completely unverified theory that this is more of a problem with cloth/alcantara seats because the cloth stretches more and does not provide as much protection for the sensor mat as leather would.

    Here is a good DIY for sensor replacement if you want to see some pictures of what this mat is and what is involved: http://www.zhpmafia.com/forums/showt...693#post433693

    It is a bit tedious as you need to remove the seat from the car and pull off the upholstery, but it is doable with a bit of patience and saves a lot of money over having a shop do it.
    Thank you for the excellent explanation.

    I guess what I meant to ask, is why did your fail so often? Which you provided hat answer as well. Thanks.
    Most times it's just me in the car. I think the kids are in it more than my wife.

    Managed to do my brake fluid flush today. It was my first time using a pressure bleeder system - man was that nice! Wish I would have gotten one of these years ago.

    They really do make it easier. Just did a flush on my son's GTI with it.
