I am having some issues with damp carpet foam in my rear driver's side footwell, so I checked the drainage FAQs I could find:

I found the front drainage holes on my E30 M40, just near the front factory jack mounts:


And this is the crap that came out:


This was from the side where the rear seat floorboard is damp.
The same holes on the other side of the car didnt have any dirt/leaves at all. I'm hoping this fixes the problem, otherwise, does anyone else know of other drainage holes at the rear? I couldn't find those.

very good link!!!

Wow thanks for sharing nick. now i know hehehehe

Hi Nick,

Did you already solved the problem?
Where you fix it and how much it cost you?

I'm having the same problem as yours....
like 'bule bela ikan kat belakang seat'.....hahahahha

Eh sorry dude, didn't notice got this late reply.

I did fix the problem, but it wasn't the drainage holes.

My rear door, the vapor barrier was not sealed properly, so when it rain or I wash car, water that flows into the door will leak into the cabin. After resealing, then no more issue.

I am referring to the transparent plastic barrier behind the door card. It is sealed with some black silicon adhesive usually.
