Hi, i have an audi a6 3.0tdi se tip which due to the heavy rains has for whatever reason filled up with water mainly in the front drivers and rear drivers footwell.

Got the car on a ramp today, and managed to get the rubber gromets out underneath the drivers side front and rear, by which a load of water drained out.

Problem is now my drivers side electric seat has stopped working a few days back. Do the electric seats have a separate fuse which could have blown, as the passenger electric seat is working fine???....or could it be worse?

Also could someone tell me where the water drain holes are so i can see if they are blocked, so it doesnt fill up with water again?

any help much appreciated.

Forgot to add the battery is in the boot, as i read the c5 models had a problem with water drain blockages.

audidep

oh, and no sunroof.

With no sunroof, and water in footwell it sounds like a cowl drain.

Seat no working could be due to a module under the carpet getting wet.

audidep

hi, sorry to sound stupid, but which is the cowl drain?

Is there a way of moving the seat or taking it out as i cant get to the module?

jakematic

Am going to have to defer to the folks who do more of their own work.
Our A6 mostly goes to the main Audi dealer.

I also found the C5 battery thread, but since your's is in the boot....

I am desperately in need of some help. This great British summer and the excellent design of the Audi plenum plugs are filling my a6 (c6) with water.

I couldn't follow the diagrams above, does anyone have any photos or video links to help. I am stressing about this now.

Will Audi help out given it is a known (ish) fault?

Ben.

Actually this a problem in a lot of cars. Not just Audi. If you live or park in an area with lots of tree debris then the drain/udders will fill. Its a maintenance problem and not a design problem.

Open your hood and remove the strip of rubber that goes from one wing to the other (No5 in the picture), then lift off the plastic cover (No4 in the picture).
Below this cover you will see something like the following picture.

Shine a torch down in the area where the red circle is and there is a rubber bung with a cross shaped cut in it, this is the drain pipe.
You can just about get at it with a vacuum cleaner hose, I taped a piece of rubber pipe onto the cleaner hose to make it easier.
If you can't get down there, remove the nuts and lift the alarm horn to one side for better access.

Clean all debris out of this chamber before replacing the cover.

It is so easy to remove this cover that you should make this part of cleaning the car.

I hope this makes it a little clearer for you.
























Sorry, the part marked "Alarm Horn" is the heater valves.
