A4 B8

Hi folks,
Anyone had the familiar problem of wet floors/carpet?
My A4 carpet drivers side is soaking wet.Tried all the usual suspects, sunroof drains, underbonnet drains but i cant find where the water is coming from.
Ive lifted the carpet today and the chassis floor is soaking wet but i cant tell where or how its getting in. Tried hosing the car down to look for the ingress, but nothing.
No evidence of water marks or it coming through the bulkhead.

Any ideas please, i'm stumped!

Thanks.

Yes mate its an avant.
The boot area and boot door seal is dry, no water in the spare wheel well.

Do you know why the avants have had a problem?

Thanks.
