theres the plenum drains which i think are the outside ones that get bunged up with leaves and crap, or the inside ones which run down just behind the carpet either side if the console. someone will be along to say any technique to do these ones

on mine it was the inside ones. i also was hearing a sloshing noise when the ac was on, basically filling up the ac box with water.

to do these you pull back the carpet round about the place where the console sweeps upwards and you will see the tubes, there is a fiddly little connector joining the pipe there , undo the connector, let any water go in to a bottle, then blow the downward pipe out with an air hose to get rid of crap. i put some paper under the car so i could see it was defo ok and coming out.

same both sides, i took out a large ice cream tub full of water from mine. i left mine to late and the water got in to my bluetooth phone unit (under passenger side) and caused the whole mmi to crash. only fixed when i removed the BT and put in a most loop.

or you can go to audi and pay the 3 grand they wanted to fix it.
