Update.
Removed the ecu and the surrounding box, dry as a bone so that eliminates that.
I hired a karcher suction vac, only 8 litres under the drivers footwell!
My last hope is the inner door seal that another member has mentioned on here.
Any other ideas? Please help! I know wear armbands to drive.
Cheers!
Hi, hope you're well.
I'm experiencing the exact same problem ... almost, and it's driving me nuts trying to deduce where it's ingressing from.
So, I really need your help guys - please !
I have a '56 plate A4 Cabriolet S-Line and recently I started to see water come out the front of the car when I reversed off the driveway after a night when it's rained. It seems as though it was coming out the front of the door sills, on the outside of the car by the front wheel arches.
This has now progressively got worse and I can hear sloshing every time it's rained. When I reverse off the driveway, the water isn't dumping out straight away now, and only seems to become less of a slosh after driving for a while but never completely stops making the noise and it's really frustrating.
I've checked under the battery, I've checked under the brake servo and these are clear and no debris or water in sight.
The water definitely seems to be moving back and forth in the sill I think ?
I jacked the car up and got underneath it, and all the holes which seemed like drainage holes to me felt clear.
I'm really at a loss here and don't want to stump up £72 for Audi's half hour assessment, and they then call back to say they couldn't diagnose it in the half hours labour time and I need to pay £72 for another half an hour and then extra on top for the repair.
Were you able to find the issue with yours ?
Any help greatly appreciated !
