2006 Audi A6 4.2 V8 water in cabin
Hello,
I have a 2006 Audi A6 4.2 V8 that has the water issue. I have water coming into the cabin from what appears to be the firewall or dash. It started on the passenger side everytime it rained. I cleaned the sunroof drain lines. I also popped the hood and cleaned out what leaves I could with an air compressor and shop vac. I thought I got a lot out. Now I have water pouring into the drivers side. I mean pouring. I took it through a car wash and I ended up with 2 inches of water coming in just left of the brake. I've searched everywhere for information regarding the 4.2 A6. Are there other lines that could be clogged in the engine bay? I saw with the A4 there are under the battery, but my battery is in the trunk. Any help would be appreciated. Thanks. Jayme |
The only thing that comes to mind is the plastic trim on the windshield. If that is no longer attached or the glue is gone or it got damaged it will let water straight into the cabin. Had that happen on my old 2002 A6 and it was pretty bad. However it is an easy fix if that is your problem. Inspect that plastic trim on the bottom of the windshield and make sure it's sealed correctly / not damaged. This piece should be glued in and sealed when the windshield is replaced. Did you have any recent windshield work done?

Bro same broblem on my a8. Check your sunroon drains. You should be able to see the hole from the top with sunroof open. Mine were clogged. I air pressured them and now they work just fine. Water doesnt get inside anymore. Fix it soon because mine flooded a module and my interior lighting is tripping now. .

I heard many people complaining about this issue and almost every time the fault was the sunroof.. So.. it must be here too I think. And it's quite logical in my opinion..
|
I have sunroof too.. I am wondering If I am going to have these type of problems too...
|
I have not experienced yet this problem.. I got my car from https://dsrleasing.com/ and I am completely satisfied! I believe that if you check once in a while the sunroof, everything will be ok.

There are plenum drains that conduct the water that runs down the windshield. If these are blocked water will find its way into the interior. This isn't only a problem with Audis. The onboard computer in our VW was fried because of this issue costing us over $3k in repair costs. This needs to become a regular maintenance item, particularly if you live in a wooded area.
There are YouTube videos that describe how to check for blockages and clear them. Do a search for Audi A6 plenum drain. |
