Porsche Cayenne - Passenger Floor Leak - Easy Fix!

- *Note: before attempting this procedure, please watch my other video to show you the absolute easiest method to check and see if the problem lies with the AC condensation drain flap. You can check this WITHOUT THE USE OF ANY TOOLS!
• Porsche Cayenne - Wate...
Please don't pay someone to do this. If you discover water in the passenger floorboard of your Porsche Cayenne, its going to be one of three things:
1.) Spilled drink
2.) Water from clogged A/C condensation drain
3.) Water from a clogged rain drain
Nine times out of ten the easiest answer is the correct answer. This video will show you how to check both the rain drains and the A/C condensation drain.
Initially it took me a bit of time troubleshooting, but hopefully with this video, it should not take anyone more than 15 minutes! Save yourself some time / money.
Tools Needed:
-Torx Screw
-Simple ratchet
-Small pliers
-Elbow grease
Vehicle in video: 2012 Porsche Cayenne
In case anyone was wondering, this also applies to the Audi Q7 and VW Tourag. Thanks for the great video, definitely helped me out!
Thanks Rayan!
Your definitely right Rayan, I had the same, exact issue, on my V8 Volkswagen Touareg
you probably just saved me $500. 10 minute job. thank you
Awesome!
The “little door” that gets plugged up is actually just a rubber disc that is part of the drain. Some dealers simply pull the disk off the end so the drain flows more freely. If you pull down the top of the carpet in that area you can pull the entire firewall grommet out which makes the rubber disk removal easier. Some dealer tech’s also modify the upper drains by cutting off some of the bottom to make them flow easier and less likely to clog.
Thanks for taking the time to explain this process … saved me a trip to the dealer.
You're welcome! Glad it helped.
..and tins of moni too....
Had water literally pouring out and soaking the passenger footwell carpet. Took to two dealers and surprisingly this is not covered under warranty. They said that its part of yearly maintenance to clean out the drains. I owned the car less than a year. Anyway the dealer said that I could leave it but could not get to it until one week meaning the car with wet carpet would sit in the lot...no to that. Also told me since this was not going to be covered under warranty that I should file an insurance claim to have all the carpeting ripped out and replaced costing probably a couple thousand dollars...no to that. I literally watched this video, unclogged the drain under the glovebox and took a wet/dry vac to the carpet. Saved me a few thousand dollars and all the headache. Thank you kind sir!
Heck yes. Just proves that anyone can work on a car if they're willing to get out of their comfort zone and use some elbow grease. Glad you saved yourself some cash. Good worj!
Hey young man, I just want you to know how much I certainly appreciate you taking the time to make this video. I'm having the same water/wet issues with my 2009 Cayenne. I'm definitely definitely going to tackle this issue this weekend. Thanks again bro!
You're quite welcome! I hope it helps to some degree. Kind regards!
@@aughtrnb Thanks! Need a bit of help. I got the panel off, but not sure how to get the hose clamp loose. Did you use regular pliers?
Excellent video. This worked for me. Get 2 large yogurt container ready to catch about 500-1000ml of water. A great Mcgyver trick: use a long rubber flexible drain cleaner with a brush in the end and you will be able to feed it through all the way to the end of the pipe and out the other side. Pull back and forth couple times and you will be all set. Try this before opening up the wheel well or reaching into the engine bay. Hope that helps!
Then use shop vac as vacuum to suck up all the water thru the wet carpet and then as a blower to dry it.
Thanks again for making this video!!
You are my hero. Your instructions were perfect and I fixed my wife's cayenne in just a few minutes
So glad it helped!
Thanks for all the posts. I took the clamp and hose off, cleaned it out and it worked for a couple of months and then the flap stuck again. I then took it out again and tore off the flap and reinserted it. It turns out I could see the drain hose from inside the engine compartment (near the catalytic converters). It seems to me the easiest fix would be to just reach your arm into the engine compartment and tear off the drain hose flap and the fix would be done in 60 seconds! FWIW
Good idea Ron. I just attempted to clear it without damaging anything but that sounds like an easy fix!
Great video. Followed your directions and it was pretty easy. Hardest part was getting the clamp pushed back. Water definitely will drip out during this process so have a water absorbent rag. I used the one I have when drying my car off after it's washed. Worked great. I tried using a long screwdriver but wasn't convinced it was opening or moving the little flap in the hose so I used a metal hanger and inserted it all the way in until I heard it in the wheelwell. After that I decided to start the car and run the AC on LOW for about 4 minutes just to see the water dripping as it should. Turned out great and overall took about 30 minutes.
Thanks again for the great video.
So glad it worked out! Its a pretty simple process. Ive had to do it twice now.
I was struggling to get the clamp loosened so I can pull the rubber tube down but been straggling. How did you get the clamp to loosen?
@@ssudhi17 I had to use a good pair of channel lock plyers and wiggle it down while using the plyers in my right hand and push down on the opposite side of the clamp with my left. Don't be afraid to use some force. Its hard but u can do it.
@@aughtrnb thanks!
This was a huge help! Applied the same process to our 2016 and were successful so far. Thanks for taking the time to post this overview.
Glad it helped!
Thank you!!! I had this issue for a few years and finally decided to look into it. I did the wheel liner drain which wasn’t bad but need to do this one. My floor looked like someone dumped a bucket of water and it always happens after it rains hard.
Thank you! Excellent video. I used a hose from a small siphon pump to make sure that the blockage was cleared. Seemed safer than using a screw driver, far less likely to puncture the tube. The close-up images here certainly helped, visibility is limited due to the tight space you have to work. Cheers!
Glad it helped. You're right about the screwdriver...but that was all i had at the time that could reach. 😀
Thanks so much for the video, just had a lot of rain and my passenger footwell got soaked! Never again :)
Glad it helped you out! It saved me a bunch of money. 😁
Thank You! I have the poor man's Porsche. 2011 VW Treg with exact same set up. I suspected that area under glove box but your video confirms it. I don't believe water leaks out of the hose but overflows from above when the hose is plugged. You may have some more water hanging around behind your dash for a couple of days.
No problem! you are absolutely correct in that the trap door gets hung up, the water backs up above the tube and overflows from the dash. It leaks down and drips into your floorboard from below the glove box. Such a simple little thing that causes such a big problem.
I believe I have this issue with a 2012 VW Tdi Tuareg. After hard rain I could hear the water gushing out on the footwell as I accelerated. The soundproofing felt behind the panel, which you remove to access the hose in the video, was soaked. @Aughtrnb thanks so much for the video! I'm wondering about long term electrical issues as there are wires running by the door threshold. My guess would be to dry it out properly the car's fan on high.
Man, really wish this was posted a month earlier!
I had the same issue in February 2019. Removed the wheel well plugs, but the problem persisted. Of course, it was the problem you described.
yes. i ve spent so much on repairing due to overflooded under the carpet!!!
Dude, you may have saved me a lot of money. Thanks!!!!
Awesome!
Great video and thank you for being so detailed. It worked on my 2014 Cayenne and saved me a trip to the dealership and money. My front passenger well had so much water that I had to use a wet vac.
Me as well. Make sure to leave a floor fan going in the floorboard with the windows down. Dry it out or your floor will smell like mildew. 😀
Big thumbs up. Just did my Cayenne, tons of water came up. I use a straw to spray silicon lube, then feel/poke that flap door 50 times until I feel that door freely moves. It seems German cars use a lot of tubs with a flap door inside to achieve one direction flow. There is no hose clamp in my cayenne, a base model.
Thanks for posting. Will work on my Cayenne this week.
Hope it helps!
I had this exact problem, and fixed it as per the description. It only took about five minutes. Sliding the steel ring off was a bit of a pain. I found a lot of debris come out and a remarkable amount of water. Hopefully it will work!
It worked. I did not open up the wheel well. Really appreciate this video. Thank you.
Great video, my 2011 just started displaying this issue. Will use your technique to hopefully correct the issue. Thanks for posting.
No problem. Glad it helped!
for my case, the overflow is repeating once a year.....
Great explanation.thanks!
Thank you so much , had the same issue in my 2016 Cayenne. Can't believe this thing is still happening even though Porsche know about it and do nothing.
Sorry to hear that. Hope it helps!
Same here. I have a 2019 Cayenne. I just found half a tub of water in the battery compartment underneath the passenger floor mat. Thank you for your time.
Helped a lot, appreciated
Ok .. last note. WD 40 silicone does not harm rubber. I used that. The VW Treg has 3 cross head screws instead of the 1 you had and they are a pain to re-install. You can replace with #7 sheet metal screw with a 1/4 inch hex head for easier Upside down install.
I appreciate the video I have an 08 Cayenne S and I’m having that issue on both sides I kinda figured it was something like that because it’s fresh water ( distilled ) not like a heater core where it would smell up the cab with antifreeze.
Thanks for the good information.
I will check mine.
Thanks! I appreciate the video. Have the same moisture show up in my 2016 Cayenne today, so I will check into this further.
Great video mate. Thanks for taking the time to do it. Very helpful.....
Thanks for the help. I have a 2008 Cayenne. Having similar issue. I thought cabin filter was clogged causing icing. But this seems to be maybe my issue.
Hope it helps you out! Takes a little time but pretty straightforward and fairly simple to do. Will save you a few bucks. 👍
Great video. Thank you for posting.
thanks, wonder if the macan has the same set up?
Top video - I'm doing to my 2012 GTS tomorrow....now to find out how to clear my rear rain water channels as I have a ton of water in the trunk! Many thanks!
Hope it helps!
Thank you! I was looking for this since the under the car did not do it.
Hope it helped! :)
Same as the other identical siblings - VW Touareg and Audi Q7..
Thank you for information
Very good information! thanks!
I stick an airhose into the rubber tube and just blow it out. Less risk of perforating the hose with a screwdriver. I've done this 2x over the last 3 years.
Great DIY video! thank you!
Glad it helped!
Thank you!!
Thank you for the awesome DIY.
You're welcome! Hope it helped.
Excellent
Thanks
Really good advice - thank you!
You're quite welcome! Glad it could help.
Thanks for the tip!
Just released a quart of water from the AC plenum. First thing I'm gonna do before putting the hose back on is replace that P.O.S. VW clamp with a regular 1/2 hose clamp.
Haha awesome. Good luck! :)
4:18 I did that, shoved a screwdriver down there, moved it Around, felt like it opened up but year later I have water in footwell again.
Thanks for posting the help. When I went inside the fender well, the rubber grommet was packed pretty full of leaves and twigs. Cleaned it out. A water flush flowed directly through.
THe hose under the glove box however, I kept putting water in it and never saw it come out. Hmmmm. Gonna have to keep looking.
Yeah it drains down and ties in somewhere near the passenger rain boot...but lower. Good luck!
Thanks for the very informative video, did this but had tons of water soaked the floorboard carpet. so pulled carpet back to dry but noticed there is a black styrophome section that i dont know where to put back in place. Can you help?
Hmmm unfortunately I am not familiar with that piece as I did not pull the carpet back to dry it out. Just a shop vac and a squeegee towel. Then I left a fan running in the floorboard with the windows down in the garage for a day or so.
Great!!!!Just what I needed.....
Thanks - really helpful -
nice job
Thank you!
Thank you very much 🇺🇸
Good video bud
Thanks!
It's like they didn't change much under the shell of the 2008. That looks like the same problem that I'm going to fix tomorrow. One design flaw after another.
hey bro, how do you undo the clamp? I don't want to break it or ruin the rubber tube
A set of plyers. Squeeze it together while sliding it off the tube. It can be a bit tough to clamp. Lock plyers would work best
Top video!
Thanks!! life saver
Awesome thank you
thanks,
This is caused because your bulkhead drains are blocked, I made a video for a quick easy fix over 2 years ago which I hope you'll find this helpful..
Don't ever use WD40 on rubber as its petroleum based and will cause more permanent damage long term.
There is more than one reason water can back up into a car. Bulkhead drains were the first thing I checked as mentioned in the video. They were clear. This particular issue was due to the stuck trap door that drains the condensation out through the firewall. And I've used WD40 on rubber window seals for years with no deteriorating issues. The WD40 website even states its safe to use on rubber. Just not on polycarbonate.
I have to do this about every 1,000 miles now. The door always moves freely when I’m done but it keeps getting stuck.
I have another video listed in my description. Watch it on how to keep the trap and door from sticking shut again. Hope this helps!
@@aughtrnb I’m gonna go see if I can find that flap on the turbo right now
@@aughtrnb lol you have a tiny v6. I have a 4.8 v8 twin turbo. I can’t see shit, engine takes up all the space in the engine compartment
Reading theses comments, I'm coming to the conclusion that Porsche should do a factory recall for this issue.
Absolutely! I had it drained just a month ago and now I’m having the SAME EXACT PROBLEM.
They really should. Things like this give Porsche a bad reputation, especially since they refuse to fix it.
@@lifehackertips Maybe it would take an act of God, or congress, for them do something about it.
@@bennysays007 what I notice is, people who Park under trees, tend to have the problem recurred often.
@@BarbermanMalik I park in a garage, no trees anywhere, never drive off road, still happened twice.
Shame on you Porsche!
