View Full Version : Water Leak Inside Car - Help needed

Ok so I've searched and found a lot of results but cannot find any answers to the problem I'm having.



It rained hard for the first time since I've owned my 99 A4 and somehow I have a huge puddle of water on the DRIVER's side floor. It started in just the back but as the day went on it has started to soak the front floor too. I found several other people had this problem on the passenger side of their car and it had to do with a drain under the battery getting plugged or the sunroof drains.



Has anyone had this problem on the driver's side of their car? Does anyone know any likely causes of this leak? Or does anyone have the DIY's to remove the carpet or remove the ECU (behind the ECU looks kind of clogged)?


Please help, it's supposed to keep raining for a few days and I need to use my car tomorrow.

hood release cable next to the ECU in the bay, this happened to me like 5 months ago, after i seal that, never happen again, also clean out the battery drain under the battery, and if your headliner is wet then is your sun roof drain, and to clean that out, you will need to take off the rear bumper

what did you use to seal it? I noticed the shop that put my amp and subs in ran wires through that hole and used some type of white caulk to seal it up but it doesn't look water tight. hopefully this is my problem. I have about 2 inches of water under my carpet

I am going to lose it. I get in my car to drive to the store and get silicon, but when I turn it on something behind the head unit starts smoking really bad. ( I have a Kenwood DDX 512 double din ) So i turn the car off and pop off the trim piece and pull the head unit out and turn the key again and something down back there is smoking like it's about to start an electrical fire. I'm guessing this has something to do with the water because my car just got the leak two days ago and now today this happened. But I don't know how to troubleshoot the smoking.

That means you're shorting something out. Pull the fuse for the radio if you really really need to get the silicone, get your radio installer to diagnose the short.

I am going to suck all the water out right now and try to steam clean the carpets. Hopefully I can get it all out. I got the silicon so I'll re seal the hood release cable hole. And then I guess I'll have to pull the fuse on the radio so I can drive to an audio place and have them figure out what that issue is about. Thanks for all the help guys

This is happening to me right now, only in the back and it's not standing water, also my cabin air filter gets water in it then it collects in the scoop under the dash and when the scoop closes from the a/c turning off it dumps water into the cabin on the passengers side where the boxes are in plastics panel hiding the wires ect. Any help on that? I was going to get a new crowl cover to help the water go over the air filter cover instead of next to

There is a piece under the raintray that covers the fresh air filter. Do you have this piece?

I believe so because the filter is covered but when I take it out there is one corner that is wet. Wouldn't putting a new seal work?

New seal for what? The piece I am talking about has the part number 8D1819979B.

Here's a pic for reference:

The raintray that sits against the windshield goes over top of this piece.
