Tempted to say my issue has got to be the rocker panel drains (or lack of) too. I'll include my pics as they may be useful for others.

    Yours look to be coming from up above, as you can see the water running down the footwell/firewall.
    Dry it out, and climb inside the car with a flashlight shining up above the pedals" have someone pour a bucket of water slowly into the grill under the window on the drivers side and see if that finds it. If it doesn't, pour a bucket on the windshield on the drivers side.

    im desperate to know the location of these rocker drains op mentions.. any pics of the little perforations in the sheet metal? I'm having a strange leak only in the rear right footwell area. i did some tests and found out that it was leaking from the windsail grommets holes into the wheel arch and into the rear footwell area if car was parked looking down, here are the pics



    See the water drop in the rear hole


    i did take the trim piece out and so the grommets, they were destroyed, i filled the holes with black rtv and inserted rubber bumps from an auto part plus taped over them to discard the leak they were causing. the leak stopped from there with the hose test. but for my surprise the next couple of days the carpet was soaked again!!
    I'm now thinking it might be the rocker drains, i did plastidip my rockers a month ago moreorless, and the problem started about the same time i figured later after reading this [post, and thought the plastidip may have covered the perforations...

    any help is greatly appreciated guys, pics would be awesome

    I traced down a 4th leak.
    ac grommet for the ac lines on the passenger side of the car behind the glovebox, next to the hood hinge.
    old


    purchased a new gasket through Irvine Bmw.

    old vs new

    new, almost done lining it up.

    update

    ac heater core has 2 metal pipes that run through the firewall on the driver side beside the brake booster.
    i traced a water leak when it rained to this area.

    remove the old seal and remember which orientation it goes it, kind of a weird shape.

    new gasket, ordered through Irvine Bmw dealer, order was sent out to Germany for the part to be special ordered.

    new vs old

    I have water pooling in the jack well of my car. I have no sunroof and I checked the trunk seals and replaced both tail-light gaskets. The bottom of the well looks like it has some kind of silicon sealant, but no vent hole on the bottom. Any thoughts?

    Under the grill, by the wiper linkage.

    Mine looks to have seam sealer that has dried and cracked....or some shit like it. If i pour water in there on the drivers side, i get water running into the drivers footwell from the seam area were the firewall meets the side of the car.
    Is the seam sealer the issue?


    The passenger side looks smooth and intact.
    that is probably whats wrong with mine because only the drivers side footwell gets wet. could you be more specific on were this seam is? is it under the grill thing? or in the engine bay?
