water ingress....drivers side and passenger rear

[Duff3103]

Hi again guys yet another problem with the a8, i came out the house this morning to the drivers footwell full of water, i left it as had no way of clearing the water and after pulling away and turning right out the street i heard a swishing noise and some water come ****ing out between the c pillar trims at the passenger side and soaked the seat.

We did have a bit of rainfall last night here but this is the first time iv come out to this im not sure if the sunroof has been left open very slightly, just enough to let it trickle in. I did push a welding rod down the drain hole to make sure it was clear. Im not sure if the drain has been blocked or the pipe has come adrift and rather than drained to the ground it has ran down behind the dash behind the a pillar trim and into the carpet. it managed to run into the fuse box but i pulled the covers off and dried out with an airline. it has since rained a little more and nothing more has come of it.

has anyone had any water ingress issues similar to this? It would be good to hear if anyone can shed light or give me somewhere to start if they have had something similar to this

thanks
