Ev, are you turning off the igntition when you stop to load up the boat? If so maybe try keeping it running....

 

that would suck water up into the engine if your no carefull. i would never turn the car off if the exhaust was under water. it does sit in the water for a few minutes while i unload the boat though. but before the touareg i did the same thing with other cars and it never happened.

 

I would think that the worst that would happen is a rusted out exhaust system. If that happens I am sure there are some really nice stainless steel systems.

 

its like that the exhaust is so large in the back that it can hold so much water. It almost looks like it could be a gas tank. I will be excited to hear if anyone else has had this problem.

 

The exhaust system IS stainless, at least the rear muffler assy is.

I've never launched a boat with my Egg. I've done some deep water river crossings, but have never noticed it. I'll keep my eye on it during the next crossing.

 

Never shut the engine off if the tail pipe is underwater. The cooling effect of the water will contract the metal and suck the water in. When you start up you could blow the muffler off the car. I can see the boat launch from our slip. Great entertainment. Boats getting loose, falls into the lake, cars sliding into the water, lots of yelling. It's a hoot.

 

So lets get this straight, you are shutting the engine off when you load or unload your boat? You fear if you didn't do it, water would get sucked into the engine? How deep do you have to go with the front of the car to get the boat into the water? The water isn't going to get sucked into the exhaust when the engine is running.

 

Like i said above, i would never shut the car off if the tips of the exhaust were under water. I back the boat in till just about half way up the tips or sometims all the way over the tips. i have to do this because its a large boat and the boat ramp levels out at the bottom, hence i have to back it even more into the water. i have had the boat for a long time an know how to back the car in, etc. etc. All i am asking is that when I back the car in the tips are usually under water and i never shut the car off, it just sounds like bubbles are coming up. I pull the car out after i launch the boat and about ten gallons of water will spill or shoot our of the exhaust tips. Someone with a boat have this problem?

 

exactly...let the exhaust burble out of the water...exhaust flows out not in...you are sucking up water since there is no exhaust flow outward.

Mike's right on boat launches being entertainment...between that and watching travel trailers back into camping spots that pretty much makes up my summer fun. Yes I need to get a life.

 

If your Touareg is fairly level with the tips 1/2 way in the water perhaps where you are getting water in is where the muffler ties into the exhaust. There could be a gap and that is where water is getting into your exhaust.

 

Why don't you just raise the suspension to the off-road mode before going in the water?

 

i do raise it up to off road level. if you dont have a boat stop replying to this thread because you guys dont know what yall r talking about.

 

i will post picks next time i go out

 

You've got me all curious to back into a lake to see if this happens on mine...unfortunately every lake around here is frozen solid.

 

it only takes me like five minutes to get on the boat and ty to the dock and then i pull it out. its deff weird, but it makes the car sound realy good, realy deep sounding if you get my drift.

Nice 'tude. Just trying to be helpful. Nowhere in your previous messsages did you say you had raised it to the off-road setting. Gezz.

 

i was not talking to you ATIKOVI, sorry if you thought i was being rude. I was talking to these people asking me if i shut my car off when i get in the water when i said that i do not like four times already.

 

Evan, I do not see how you are ingesting water into the exhaust system with the engine running. There are no holes or gaps in the exhaust or you would have a serious exhaust leak when dry. The exhaust will get louder and sounds deeper due to the water cooling the exterior of the mufflers. As for you shooting water (approx 10 gallons) out of the tips, I'm at a loss. I too, am in South Texas and have made creek crossing and "waded" through quite a bit of water. I notice the tone changes after leaving the water and I know my Treg sounds like an outboard while still under water. I have parked and exited, to see the water line and check my fog lamps for water infiltration. I've noticed alot of water dumping from voids under the body but never observed water shooting out (even seeping out) the exhaust tips.

I wouldnt worry about it though as long as you have a decent drive home to dry-out the exhaust system. Alot of the system is stainless and designed for water exposure.

BTW, you out on Travis, or LBJ?

 

i think that i will go down to the dock this weekend and make a video so everyone can see it.

 

I'm sure it would be ingesting some water if the tips are submerged, based on the fact that at idle, there's probably not enough exhaust flow to offset the water that's wanting to flow in and occupy the space in the exhaust. If there was more exhaust flow (like the engine was revved up), it may not happen as much, since there is more exhaust gases and pressure pushing back against the water.

I can't really comment on longevity, but if the exhaust is stainless to begin with, you likely won't have much of a problem, as long as the drive home evaporates/blows out most of it. I don't know what kind of packing material (if any) is in the muffler, or what effect that much water may have on it, but I'd think it'd have to be somewhat moisture resistant, as condensation goes through there anyway on cold humid mornings.

One word of caution though: Don't back the Touareg into the water too deeply. The air exhaust vents for the interior are down behind the bumper cover. Check this thread for posts from Arkarch and myself for more info:

Wow. It's amazing just how much dirt gets in behind the body panels... (that is dirt, right?)

 

Evan, a video would be great. Include your boat and trailer in it also please!! I am a boating aficionado although I have yet to trailer it with the Treg. I know the configurations and problems with ramps are almost equal to the number of ramps out there so a video will help. But is the Treg still on an incline while you are (un)loading the boat?

I guess I also am not "getting the picture" because I would have guessed that gravity would have drained most of the water before you exited the ramp.

I am not trying to be rude and it probably wouldn't do any good, but if you have to put the Treg, while in off-road, that far in the water, the owner needs to get off his arse Dead Horse and do something with the ramp.

 

well our lake is a drainage lake that maintains all the lakes down to the gulf of mexico, since we have no rain its about 40 feet low. dont worry you all will know what im talking about after this weekend. the egg is also on about a 30 or so degree ramp, when you get the trailer in all the way it levels out, not the egg. here a a few picts to tie u over, im the one drivin

 

There's not many things in life that beat lounging around on a boat all day and sucking back a cooler full of beers. :drunk:

 

i think my friend there drinkstoo many beers, he looks like he has tits

 

LOL, well I admit I've been into the beers too much too...I have the same problem

 

same issue with Cayenne S

Hey Evan,

I know it's been a couple years since this post was active... just had the same issue with my '04 Cayenne S. Exactly as you described... and NO (everyone else) I DIDN'T TURN THE ENGINE OFF WHILE THE CAR WAS IN THE WATER... after pulling everything out, I made sure I got as much of the water out of the muffler as I could before finally stopping the car.

So bizarre... with a 7700 pound towing capacity I would think that many people with larger boats (having to back in to deeper waters) would be reporting the same thing. I've backed many boats down ramps with other trucks and heard the exhaust gurgle while temporarily submerged... NEVER have I seen gallons of water come shooting out of the exhaust after pulling the truck/trailer out of the water.

Called my Porsche dealer and they seemed puzzled by it too... hmmm.
