Default Audi A4 - Water Leak

I noticed water accumulation in my audi on the left side front and back after a heavy rain storm a couple of weeks ago. I tracked the leak to be occuring because of a fault in the front left drainage tube of the sunroof. Somewhere between the beginning and end of the tube there must be an abbration because it the leaks into the left side of my dashboard, then down and out onto the floor. The question is: How hard is it to get to the tube and what should i replace it with. Can a person, with the right tools, do this without a proffessional mechanic?

later i'll post pictures of exactly where the water is coming in etc. but i don't have time right now.

See if yuo can use an air compressor to clear the tube of any blockage. It sometimes works.

Replacing those hoses is a real pain in the ***. Most of the interior has to be removed to acess the ends of the hoses. All of the pillar panels have to be removed to get the headliner out. The hoses are foamed into place. Theyre a real pain to pull out. Youll want to use the old hose to pull the new one thru. Its very hard to fish the new one thru. Definatly try blowing them out first thou.

Don't wait to get this fixed, my sunroof hoses were clogged and caused my door locks/window air pump to quit working all together, $1,150 to fix.

I dont think the tube is clogged. Water runs through it fine and comes out where its supposed to come out, but after about a gallon, it leaks into the car as well. may it still only be clogged? it sounds like i wont be able to replace the tube myself but the dealers will definately charge some serious cash for a tube replacement. any other ideas?

Ok, so for anyone that has a waterleak on the left side of their car PAY ATTENTION! This is EXACTLY what is going on in my particular situation:






---READ---
In the pictures below, the yellow highlighted area just indicates that normally there would be an interior trim panel there, but i removed the trim in that area to get a better look of whats going on. The green indicates the path of water out of your view (inside the pillar) or its just an arrow showing you something in the picture. The blue is visible water exiting where it is supposed to exit. The red is visible water exiting inside the car, where it should not be.









Click the image to open in full size.
Heres a picture of the general left side of my car just in case.




Click the image to open in full size.
This is the left front corner of the sunroof. To the left is the left side of the car. the arrow is indicating the location of the drainage hole which is out of view.




Click the image to open in full size.
this is a close up, so you can see the exact location of the drainage hole.




Click the image to open in full size.
Here you can see where the water is supposed to enter, and where the tube runs down the pillar, and where it is SUPPOSED to exit (water coming out in the correct place is blue). You can also see where the water is entering the car (generally, not exact -- this is in red)




Click the image to open in full size.
Here is the exit point for the water on the outside of the car. it's under the hinges of the front driver's door.




Click the image to open in full size.
Another picture that shows whats going on inside the car.














does this better explain what's going on for everyone. i will see massive water leaking in after pouring about a gallon of water into the drainage point and no less. This weekend i will try cleaning out the drainage tube at my brother's work.

Default RE: Audi A4 - Water Leak

no problem, i had taken the pictures earlier so i could explain to anyone who needed. If you think you're having the same problem, get to fixing it quick. if you look at the pictures, you'll notice the flow of water runs right over the fuses and a load of electrical wires. NOT GOOD. it could cause serious problems so try to fix it quick! i need to do the same.

edit: i'm glad everything made sense there

Default RE: Audi A4 - Water Leak

We had water sloshing around under the driver's seat and in the left rear passenger footwell of our 2001 A4 Avant. Audi diagnosed it as blockage under the plastic covering at the base of the windshield under the hood. They descibe that area as having two "bowls" that can accumulate leaves and debris. When the bowl drains get clogged, heavy rain fills the bowls to overflowing and it comes into the cabin.

You might look there as the isue may not be related to the moonroof drains.

You just reminded me of something. That is right where the avants run the water hose for the rear wiper washer. Not unheard of for that to leak in that area. Those pictures dont look like an avant but if it is an avant thats something else to think about. Its usually just a fittiiing that gets disconnected in that area.

The bowl you speak of, its the one that is on the far left hand side? because i believe i know what your talking bout. i think this weekend is going to be a trial and error one for me bacause there are alot of suggestions of what it might be.

Default RE: Audi A4 - Water Leak

Is there a way for the water to accumulate in the rear drivers side footwell in addition to the front? I am new to the A4 (I've owned it 4 days) and have the exact same problem, although I found at least a half inch of water in the rear as well.

Default a4 water leak

hey this an old thread but im replying mostly to ckandes 1 and hopefully il help you guys out..

i have a 98 a4 and in heavy rain, water pools (literally standing water) in the drivers side floor area as well as in the seat behind it...water has never reached any rightside area of the car... uhmm... ive gotten the water out by wet-vac sucking it up and then fan drying it over night - works very well and saves the hundreds of dollars it might cost to have it done at a shop..

the leaking water problem only happens in moderately heavy rain (and i think it happened when i washed my car once) so ive read some stuff online and came to think that is was a leak or busted tube from the windsheild overflow into the floor of the car...the water itslef has no oily or engine smells and has usually smelled like dirty rain water which confirms my belief of a outside leak..

until recently i didnt consider the sun/moon roof thing to be another cause but i think that it is probably exactly what it happening so if any of you has a problem like this check two things first: 1. a leak from near the windsheild drain off, 2. a leak from the sun/moon roof drainage system

interestingly enough ckandes said that this water could be running over fuses and wiring and just after i noticed this leaking water problem, my back left window stopped working completely...my guess was that is was a simple fuse problem..and now i think i know exactly what it is and what caused it
hope this helps
