Alright. I gave it a honest go. Did the best I could do, in my driveway. And I was not successful getting to what I wanted to get to.

Ultimately, with my situation, I will have to go the long hard road. To fix my tank leak. The sub-frame needs to come down. The drive shaft needs to be removed also. Not a driveway job. Brake lines.... Fuel lines.... Fuel fill neck.... Various wires....

I need rum,

Good Grief Charlie Brown. Leave that football alone! Take that drink and calm down.

What I am reading is that you have "guessed" that it is one of those lines on the top of the tank that have broken/come loose. If that has happened, it is the very first time that I have ever heard of that happening in a Q7/Cayenne/Touareg, period. There are a few places that seem to sometime leak, but that is not one of them.

Now, lets try to troubleshoot this. Now, what we know is that when you open the door, the fuel system is pressurized before you even start the Touareg. That is why you hear that little buzz when you open the door. It is the fuel pump starting for a couple of seconds. Now, the computer does not do this every single time you open the door. But, when the car has been sitting still, the fuel pressure drops. Now the fuel pressure is low and when you open the drivers door, buzz, buzz, buzz, the fuel lines are pressurized, before the engine is started.

Now this is important since that it would move the gas. If you have a leak, then you will start to smell the gas before the engine is started. If you have a large leak on the pressurized side, you should start getting drops of gas going somewhere, eventually landing on the ground.

Now, if you are really smelling gas, but not seeing any drips, then you probably have a smaller leak. Still dangerous, still smelly, but it is not a huge leak. A huge leak will end up on the ground. Are you finding any gas on the ground?

If you want to get an idea about the system, here is a good link. https://es.ifixit.com/Guide/Fixing+...ng+2004+2005+2006+2007+2008+2009+2010+Volkswagen+Touareg+Touareg+Gas+Leak/11326

Why don't you take it in and let the dealer do the fuel recall?

No spills on the ground in my parking spots, at home or work(I think).

Why don't you take it in and let the dealer do the fuel recall?

Because it isn't a flange issue. The only thing they can do, is drop the tank. An estimated 8-10 hours of labor.
Only then could they assess the problem. It was suggested to buy a new tank, before starting the process. So I wouldn't have to wait for delivery, and down time would be at a minimum.

Essentially, they don't know. They don't care(in my opinion), because to go through that much effort. Replacing it would be the only sensible solution. I didn't ask for a price on the tank. Because I'm not going through the dealership. Also, it's not worth THAT kind of money. In my head, I'm thinking this kind of job is going to run me $5,000 out the door. I bought it for 3k, then invested another 1K. It just is not worth it.

We have a local VW guru, here in Houston. The guy has been ranted and raved about on my TDI forum, and Vortex. I've been to him several times over the years. I'm sure he'll tell me the same thing as the dealership. Except he would rather look into repairing it, to save money and possibly time.

I'll see what he says, then make a decision,

So, per your above answer, it appears you have had it verified per the dealer technician that the leak is not related to the recall. Where did they tell you the leak was from? Anything anyone else at the dealer said does not matter. In the end, it the the tech who makes the warranty call in this situation.

I was under the impression that you were refusing to take the vehicle in to do the leak recall. Worried that the dealer would find a unrelated leak and hold your vehicle hostage.

Frankly, the dealer could state safety problems and refuse to let you drive it off the lot. The short version of this is the dealer calls the cops and tell you they will hand you the keys when the cops arrive. The cop will tell you not to drive it off. Unsafe = not road legal. But, you can still have it towed.

A real jerk dealer could attempt to hold the vehicle hostage, but your call to the police would remedy that quick. The cops would tell the dealer to release the car back to you. In the end, dealers can not legally just keep a car hostage.

Have you had either the dealer or someone else qualified check the top of the gas tank (via the holes under the rear seats) and verified that there is no gas or evidence or gas anywhere around the top of the engine. IMO this would need to be outside, with the engine running, and it would take a minimum of 10 minutes of observation to be certain.

If you don't or won't trust the dealer, why don't you ask the local VW guru to look over the problem?

I will not mind being proven wrong, but I have not seen any gas tank failures and so far I have not seen any real evidence that you have (1) checked and ruled out much more common leak areas and (2) that you have actually found the source of the gas tank leak. From what I can read, it seems that you have just decided that it must be the gas tank. That is an expensive jump to make and will cost you many thousands of dollars in what could end up the wrong repair.

Heck, before I pulled the tank, I would be looking very closely at the filler neck. Now that is the only other area that we have had a problem with and it was a rare problem.

I hope you the best, but unless you are good with a wrench this is a expensive car to maintain. If you do find and repair the leak, an update would be appreciated, but this is probably the last post I will make.

I can not think of anything that I have not covered. Sure it could be the tank and it could be a pinhole leak in a hose, it could be so many things. But really these vehicles are famous for one gas leak problem and they can do it without having a huge pool of gas sitting on the top of the engine. Sometimes, the leak is mostly gas vapor and any evidence is very hard to find when the engine is not running. Get a mechanic to look it over before you try to just replace the entire tank.

Sorry, for the confusion.
I didn't take the truck in, I simply called the dealership and asked about it all. So, no. There was no definite answers as to what is going on.*

I was under the impression that you were refusing to take the vehicle in to do the leak recall. Worried that the dealer would find a unrelated leak and hold your vehicle hostage.*

But, you can still have it towed.

And I still am! Is that strange?*
I honestly am worried about a hostage take over. Right now, this is my only working vehicle. And the PD getting me for gross polluting.*

If you don't or won't trust the dealer, why don't you ask the local VW guru to look over the problem?

I'll plan on taking it to the guru this weekend. However, I'm afraid that he'll say something similar. And have to drop the tank from the truck. Just dropping the tank is not so simple. As explained before. I think I'll go in for a diagnosis first, see if he can find something without dropping everything. Bring it back, when I have more funds something like that.

I will not mind being proven wrong, but I have not seen any gas tank failures and so far I have not seen any real evidence that you have (1) checked and ruled out much more common leak areas and (2) that you have actually found the source of* the gas tank leak. From what I can read, it seems that you have just decided that it must be the gas tank. That is an expensive jump to make and will cost you many thousands of dollars in what could end up the wrong repair.

You're not wrong.*
The first thing that I checked was the fuel pumps. I popped the cover off, ran the engine to see if I had a ruptured/broken housing like in the link provided. I don't have that issue, the leak is not from there. Also the leak first happened while the truck was turned off, and I was filling the tank. So I ruled out electrical based operation(s).

It's true, that I haven't looked at the filler neck. The only reason why, is because when I did leak. It was all from the driver side of the tank. Not the passenger side.*
That's my only reasoning why.

Heck, before I pulled the tank, I would be looking very closely at the filler neck. Now that is the only other area that we have had a problem with and it was a rare problem.

I can definitely do the searching. Maybe I did jump the gun, by keeping closed minded to options. It just SEEMS like everything leading to tank drop. How does one check the filler neck with it in the truck?

I hope you the best, but unless you are good with a wrench this is a expensive car to maintain. If you do find and repair the leak, an update would be appreciated, but this is probably the last post I will make.*

I'll still don't think is a breach in the tank. Possible broken fuel line? I don't know about that either. I still think it's that pick up port, on the forward most point of the tank. All of that is basically on where I saw it draining from while at the fill station.*

And you're correct:

Broken fuel pump

Fuel flange

Filler neck(still have to do my homework)

That's it! No other recorded problems. Which is why I am also confused.*

All we can do is wait for the report from the shop. While I am handy with a wrench, I am no technician. And I'm getting out of my league.*


We'll see what the guru says. Stay tuned,*

I wish you the best. I have managed to come up with a tiny bit more that might be helpful.

1. Never overfill the gas. It will come back to bite you if you do.

2. The filler neck is a nightmare in modern vehicles, especially this vehicle.

3. I have also seen shops that will use a pressurized smoke machine and then try to find the escaping smoke to pinpoint leaks.

Look over this. It might help. Whoever diagnosis this problem will need access to a inspection camera (camera on a long stick) to figure this out.

I don't really post much here, but wanted to let others know about this issue. I had this problem in June 2017. I purchased a new VDO fuel filter flange from Ebay, the retainer ring and gasket from a VW dealership. It isn't hard to do. I did the work myself and the 3 parts cost me around $110. I did lubricate the gasket that makes contact to the retainer ring & body of the car with a non-petroleum lubricant. I received a recall notice from VW and asked to be reimbursed for the parts ($110). I submitted the claim with receipts and photos and they denied my claim. I think the reason was that the fuel filter flange was from VDO and not directly from VW. Of course everyone knows that VDO makes the part for VW and the file the VW logo off to sell it on the aftermarket. I hope others are more successful in getting reimbursement. It is kind of sad. One guy in this post was charged $790 for the repair. I did it for $110 and that is all I wanted. VW is too cheap. If any need the correct part # or help, please let me know.

ZeroR2, since it is an active recall, go file a safety claim at the NHTSA website.

https://www-odi.nhtsa.dot.gov/VehicleComplaint/

Reference that your problem is a safety defect, leaking fuel and that you repaired it. Then note that you found VW active recall for the problem, submitted the repair bill parts cost to VW, and VW denied to reimburse you for the recall.

Eventually VW will be forced to give you the $110 back because VW does not like active tickets in the NHTSA website. Yes, VW is a really cheap ^&%*%*!

 

[nickyt]

Since we wanted to expand on exactly how cheap and terrible VW has been recently.

That’s absurd. According to these court documents, engineers at VW had the audacity to issue a software update to customers that dialed down emissions control usage and spewed more NOx into the environment, just so the company could save a (warranty) buck.

https://jalopnik.com/vw-made-its-defeat-device-more-potent-to-save-on-warran-1786442999

Yes. VW knew the adblue system was defective and deliberately made sure that the part failed after warranty so that the customer, not VW, would have to pay for the repair!

 

[ZeroR2]

That is actually what I did. I didn't know that it would be PITA to them. Thanks for that information. I will update the results. They were sure quick to deny my claim. VW said it would take around 60 days to review and I got a denial letter within 1 week. It was rubber stamped.

 

[ZeroR2]

Follow up: Here is the response from NHTSA.

Unfortunately, riembursement is not a matter that NHTSA has jurisdiction over. The NHTSA Hotline Information Center can provide you assistance and information regarding vehicle safety, recalls or motor vehicle equipment defects.

 

[nickyt]

Drat. Sorry about that. At this point, it might be hard to get VW to pay.

 

[ZeroR2]

Drat. Sorry about that. At this point, it might be hard to get VW to pay.

The interesting part is this (on NHTSA website)... I need to think about next step????

If I pay for needed repairs before a recall is ordered, am I entitled to reimbursement?

Yes, under certain conditions. Manufacturers are required to provide reimbursement for certain costs incurred by owners to remedy safety defect conditions prior to a recall. Vehicle manufacturers are required to reimburse owners for costs incurred to remedy a defect based on either (1) the date NHTSA opens its Engineering Analysis, or (2) one year prior to the manufacturer’s notification of a defect to NHTSA, whichever is earlier. The closing date of eligibility for reimbursement of repair of a motor vehicle is 10 days after the manufacturer mails the last of the owner notices informing owners of a safety defect recall and cost-free remedy. For replacement of equipment, the closing date is either the same as for motor vehicles or 30 days after the manufacturer’s closing of its efforts to provide public notice of the existence of a defect, whichever is later. Documentation of the costs is required for reimbursement. While the current reimbursement policy is a relatively new requirement, manufacturers have in the past often voluntarily agreed to absorb such costs, provided customers could prove the pre-recall repairs remedied the defect in question.​

So I just had my recall done on Tuesday and somehow my fuel pumps might have gone out today. Limped it to the closest dealership because I'm a few hours from home and my trusty mechanic. Is there any way the dealership could have created a vacuum leak or anything else during the recall fix and my fuel pumps are fine?

[Built4Sin]

Could be a bad seal, when they put the new tops on. A few YouTube videos mentioned just changing the filter is dicey since the seals for the pump assembly don't always seal tight after being opened (plastic top and bottom halves that hold the filter, not the tank itself).

 

[dferrero]

fuel pumps fail with recall repair?

Fuel Pump Flange recall supposed to be about an hour of work. After 4.5 hrs and several attempts dealer is saying both fuel pumps have failed...not producing enough fuel pressure. The symptoms were engine stumbling after starting. Low 400 rpm idle and pressing on the gas pedal and nothing happens. Multiple techs and troubleshooting later and no-go. I've never had problems, never smelled fuel, never had any idle problems...I expect the dealer to deal with VW to sort out whatever the final repair is needed...but I drove in with a fully working Touareg, I expect to leave dealer with a full working Touareg. I left with a loaner about 5.5 hours after arriving.......to make it more "odd", dealer said another 2004 Touareg came in for the recall work and left with two new fuel pumps also..same day...I have a call-back scheduled with VW Customer Care to get out in front of this... Also wondering what will become of my just-filled fuel - I think it took 22 gallons it was on empty. Looking for advice and/or tips on sorting this out with dealer and/or vw before anything escalates.

 

[enchanted egg]

Why is this only going back to 2007? I just replaced the part on my 2005 V6 because of the same problem.

I got the letter and I have a 2004 V-8.

That is strange..

Below is a link to a fuel pump replacement. It gives you a good overview of the fuel tank parts.

While both pumps going bad at the exact same time is possible, I would be looking at other things. Like, perhaps the dealer kinked the fuel line. Or since both pumps go thru the single fuel filter, perhaps the filter is clogged up.

Both problems could make you have low fuel flow rates from both pumps.

My understanding is all the dealer was to do was to put a plastic seal or wrap over the top of the fuel cap. Do they even need to remove the cap (aka open the fuel tank) to do this. With one hour of labor, I doubt the fuel tank is being opened.
