I have a 2003 a6 2.7t q. It has about 36,000 miles on it and I bought it used a few months ago from a dealership and brought it to audi to get check out and everything was fine! Today I get into the car and the right side (both front and back) is flooded with about 6 inches of water. It was not on the leather, just the floor. No windows, doors, or sunroof was open. I'm confused as to what is wrong and i was wondering if anyone could give me some guidance before i call audi or a mechanic because my parents are reluctant to pay too much money to get this checked out. Please help! thanks in advance

 

Do a search for clogged battery drains & sunroof drains.

I would not start your car until you dry out the computers located under your drivers seat.

Best of luck and welcome to the forums.

check the plastic trim at the bottom of yuor windshield near the wiper locations. if it is not put back perfectly and sealed right it WILL cause water to leak in the car towards the right side, near where the cabin filter probably is

 

oh and yeah checkj the modules under the front seat, I know the TIP trany module is there (you even have an Auto? or 6 spd ). Remove the carpet and check it out, dry things out... There is a screw on the right side in the passenger footwell, wehre the kick panel is near door frame... unscrew it, unclip the whole vertical trim, thenremove trim along door sill, lift up the carpet and chekc it out

 

It's an automatic. Yeah, we removed all of the carpeting etc and unscrewed the panels and found that all of the wires were wet so i'm drying that out now as best i can. As of now, the electrical stuff in the car is not working properly. The abs sign lights up and all the gears light up in the display. I'll go check out the plastic trim near the windshield as well.

 

I checked the seal near the windshield and it's completely sealed. I'm guessing it's the sunroof drain. Now i'm just waiting for everything to completely dry out(i've been vacuuming and blow drying).

 

Did you open up the transmission and central convenience computer? Make sure you do that and dry them out. Were you able to verify the drains under the battery were not clogged. I would say they are the most common reason for our cars flooding.

 

I would second Jeff's opinion.
As someone who "unclogged" (they were unobstructed in any shape or form) the sunroof drains, I can vouch that there's no way water from a leaking sunroof would pool on the floor without the headliner being soaked FIRST...
Secondly, IF you would have had clogged drains, water should have been present on the driver side as well.
Is gotta be your firewall drain hole that's clogged. The water sips through the fresh air vent flap.

 

Okay thanks. Honestly, as a girl I know nothing about cars :x so this help is very much appreciated. My dad isn't home at the moment to check the drains under the battery either so is there any way i could do this? Also, how do i check for a firewall drain clog? Thanks again

 

We are talking about the same drain(my car only has one)s. The firewall is the metal panel (wall) in between the cabin and the engine bay. I guess it suppose to protect the riders from a possible fire in the engine bay - hence its name.
In between the lip of this firewall and the windshield's base, you suppose to have a plastic cover (cowl), which if you pop out you can access the battery. If you have a 10 metric (the most common size for the battery nuts)wrench you can remove the battery (+ terminal first) and you should be able to locate the drain(s).
good luck.
