Not used the car for a while and jumped in it yesterday and could smell dampness.
Had a wee look today and passenger side floor is wet under the mat.
Ive looked above where it would be and around the fuse box area is dry n dusty so that would rule out from above...
Under neath the carpet inc the foam and insulation are bone dry, sides around the damp patch are dry.
I've put the hose over the car and still nothing... It's an isolated spot as though someone has poured a jug full into the middle where your feet would go. Suggestions please

Oh, car is E91 330i with paroramic sunroof...
