Wet Carpet

[topcat]

Hi

I am new to this site, but I wonder if anybody could advice me in the right direction.
I have 3i8i salon (E46 shape).

I noticed my front passenger side carpet very wet, I was then trying to trace where the water was coming from by feeling the carpet near the side and front but the carpet was completely dry there. I am now a bit baffled as the carpet is only wet at the bottom and not the sides.

Just to put you in the correct picture, I park my car on my sloped drive could this be any help to find where the leak is coming from?

Not sure if the same would happen if parked on a straight/flat road.

Thanks in advance for any tips.

I had the same thing and it turned out to be the vapour barrier inside the door. If this is not 100% water leaks straight into the footwell. To fix it you need to remove the door trim and fasten the membrene back down

A question...Did this happen after a heavy rain?

Not to sure when it happened, I have 2 floor mats so the main BMW ones don’t get damaged hence I did not notice the wet patch straight away.
I only came across this at the weekend when I was cleaning the car.

It hasn’t rained heavy for few days but the water could have been there for some weeks, not sure.

Any ideas what the cost would be if I was to get it repaired by a main dealer.
