I have an 04 Audi s4 Cabriolet, lately I have been suffering with water coming into the driver's side footwell (only) I have had to scoop the water out on a regular basis (up to 3 pints once).
The water appears to occur when it has rained quite hard, I have had the gutter channels under the battery checked and this is all clear and working. It appeared the 1st time when I drove through a very deep puddle which came up to the cill, the next day it was flooded. The water always appears to be a dirty grey colour (this maybe the colour of the carpet running)
I took it to my Audi dealer and they wanted £300 just to detect the fault!! (very helpful as usual).
Can anybody help me with my dilemma
