hmm when i googled such issues there are some other plugs further back (cant remember where) but a call to you local Audi garage should help!

Also i heard that there can be a gap behind the computer and the engine bay as the rubber seal could have perished...this would cause water to trickle into the foot well too

happy hunting

Hi Guys,

I just had this fixed. Having removed the whole dashboard and had the Aircon inspected that was fine and a slight fools errand really.

Because if you check the drain from the battery shelf you will notice its blocked, which was a common issue with the A4 cars and when bought from new all the owners were directed to their Audi garage to get it unblocked.

So when it rains the water cant drain away from the battery shelf, causing it to run into the car as you start to drive and jerk around in motion with movement of the car...have the battery removed and the drain unblocked and you will save hours of investigation and money plus anguish and save your leather shoes!

HI Steve Q

thanks for the comment as I have googled similar solutions, plus the rear drain tubes & the seal under the ECU box can fail on the driver's side...so I have my work cut out for me!

Hi, I have recently bought my fab A4 Cabriolet but sadly I have noticed the drivers side footwell filling with water when out driving! I have had had the aircon striped out and pipes unblocked...but the leak is still there!!

Any help /  ideas would be much appreciated please...
