Default Gas fumes

I have an '02 and for several months have been experiencing strong gas fumes, both while sitting/parked and to some extent while driving. Sometimes as strong as if I was carrying a gas container in the cabin. It is especially strong upon fill-up or sitting in garage. Familiar to anyone?

I just completed 80K service and TB. Indy did not advise any issues with gas smell but did fix a couple of vacuum hoses too during service. CEL was on before going in and was only off for a few days afterwards.

CEL (lean condition) is back on and had indy inspect, VAG/recheck and clear it. This light has continuously been on for several months and Indy felt nothing serious (barring any blinking) as likely another hose leak somewhere that he could not readily id without further work (smoke, etc) --He advised to investigate at next service interval or earlier if notice performance issues.

I don't record gas mileage (aka I don't want to know lol) so not sure if it has been affected and driving performance doesn't feel to have been deteriorated.

I feel these fumes are likely the cause of the CEL -- could gas fumes be related to the lean condition as code always indicates?? Has anyone experienced this and if so how resolved, repair, idea of costs? Thanks.

yes.. lean; not enough fuel to the engine. You have a leak and its a dangerous one to wait on.

Ok,wonderful ...I'll call the indy tomorrow. Is this something common and have you experienced it? Venture to guess on how intensive/costly to fix? If in fact a gas leak (seemingly obvious to the nose) it must be small because I don't see any puddling...good thing I don't smoke huh. One positive angle I could see some mpg improvement!

MPG improvements on the dashboard computer or actual miles driven per gallongs you poured in? Keep in mind that if your car is squirting gas around engine bay and that fuel was meant for the cylinders to burn in, your car thinks it burns less (since less fuel makes it into the cylinders) but you are still epxending as much or even more fuel than normal.

If I had a guess, I would say that a fuel hose or regulator in engine bay is leaking on you. Or maybe even injector. Neither one is safe as the second the fuel squirts around manifolds you will have engine bay fire.

Thanks for the input. I am calling the indy in a few minutes and this could help in the dialog. I'll check back with outcome.

the smell is not a common issue. The cause can be anything from a faulty gas line to a valve to the tank, etc. No way to diagnose on the web.

Just returned from Indy and diagnosed a leak in top of fuel tank...likely coming from evaporative hose or its entry point area to tank. Either way mucho, mucho labor ($$$)to drop tank to repair or even more labor to replace tank which in of itself is costly too. A used tank could be sourced to trim costs but repair time is unchanged.

Most importantly it was determined there is little/no risk for fire because of rear location and small size of leak. Because of this I am leaving unrepaired for now and avoiding topping of the tank as causes more leakage due to splashing. A repair estimate of $1400-$2600 makes this an easy decision for now. Unfortunately must now live with CEL and could make any other future issues less apparent. I would prefer to save for the eventual valve cover and suspension repair.

before you do this...... play dumb.

Just go to the dealer for the rollover nipple recall repair. It involves dropping the tank. They may fix it as part of the repair.

Call the dealer and give them your VIN and ask if the recall was done, as you bought it used, etc.

Yup, there was a recall for these tanks and it is a fire hazard hovewer you look at it. I think AoA can be pursuaded to cover that if it is not a part of recall already.

Wow, that could be huge..thanks for the info paulroad!
This sounds exactly like the problem I have.
Tks thejulex, 10-4...just checked this site and my car should qualify as part of the '02 recall on 4/8/08.
http://www.usedcarsplus.com/audi-rec...oad/index.html

I purchased this car as a second owner back in '05 but never rec'd any kind of notice/letter for this particular problem...hmmm.
I am hoping my VIN is included and if not it should have been.

I will gladly call my local dealer first thing tomorrow.

Thanks again -- Stay tuned!

Bad news and bad news....first, the rollover recall was completed on my car last year. This was my bad as I actually had the letter/docs/receipt etc...however my confusion was started after getting a 10 hrs. labor quote from my indy and I would have remembered such a repair of that extent. This is why I didn't even check. Come to find out the dealer told me it took them only 2 hrs as position of recalled nipple was on top/front of gas tank -- much easier to get to as only need to drop tank a foot to repair. Second, and here's the bummer, my leak is coming from a different nipple (or could be crack in tank) located in top/back of tank so would require total drop of backend including axle to completely diagnose and then repair. Either way it's a 10 hr min labor deal!! plus added cost of epoxy repair or worst total replacement of tank - the latter requires still more hours of labor beyond the exorbitant part cost.

Drumroll please...total costs will range depending on actual source of leak - from min of $1000 (simple nipple patch) to $3500 (new tank replacement). OUCH!!. Thought of the day...if tank needs replaced do I go with new at $2500 or used and save a ton of $$. Either way SUCKS because buying new only replaces with the same crappy, engineered part or used gives you the same with no warranty. And know what's worse than this?...making the repair and knowing that it's likely to break again right after the warranty period - and should you get lucky that it happens under warranty my guess it will be for parts only - gee thanks!

With other costly repairs just waiting on the horizon I guess I will be only making half fill-ups and loving that sweet aroma of gas fumes.

Last suggestion....

If it were me, I'd call AoA..being extremely complementary about the car, the service, the dealer etc. Let them know you have maintained the car by the book and did the recall. Now a year later to find another tank related issue..gas, smell, etc.

AoA has been known on safety items like a tank to bend over.. and good will the repair. Sometimes 100!, sometimes parts, or 50%..it varies. But nothing to loose by trying.

Crikeys! That's what an Allroad gas tank looks like? Sheesh, what a complicated blow mold piece.........it's a wonder any of them hold gas......I assume the OP's problem is with one of the other nipples up on the level where the filler port is?

This is good to know -- certainly not that you had problems but confirming others have had similar if not worse experiences. This is my other large concern...when will the next leak spring forth. As allroaddave stated so eloquently "it's a wonder any of them hold gas". Also as thejulex I believe hinted...there was a time prior to the recall that entire tanks were being replaced??

In any case AoA did contact me and the dealer today and advised they would get back to me -- extremely responsive considering I just sent the email yesterday afternoon! Certainly refreshing in these days of customer no service.

Allroaddave, would you mind terribly saving me some time and provide a brief synopsis...same problem/location of leak on each? resolution?

As it now stands they are confirming if this falls under the recall...already determined it does not --- and possibly confering with the service mgr. As eluded this individual's input might play a significant role in how this might be resolved. This would be unfortunate as inevitably objectivity would be put into question. The line "loyalty has its privileges" comes to mind --- doesn't bode well for those who use indys.

It my stand that the dealer should not be put in the middle of these cases.
Sure, they are needed to confirm problem and diagnose but hopefully stop short of opinion/stance.
While I respect and condone that loyal customers deserve special treatment certain situations like these sit outside those lines. It is my contention that it is a badly designed part susceptible to defects, recall or otherwise. While I understand and appreciate that a recall (voluntary or not) was initiated on a certain part of the tank, still this should not preclude them from accepting responsibility for other documented safety flaws. I hope and trust that they will see this not as an isolated, infrequent incident but one in which they have an obligation to further protect its customers. Here's to doing the right thing!!

I agree, based on what I see in the pic of the tank and the closeup of the broken nipple, what's to keep one of the other nipples from doing the same thing - same materials, same construction, all three have to be intact to contain the fuel.

I'd be curious as to why the one in the pic broke, what caused the torque or vibration that fractured the plastic? Did the hose come out of it's retainer or...?

Does gasoline cause the plastic nipples to become brittle and they just break?

Enquiring minds want to know!

This is why such a repair paid by AOA is called a "good will" repair. Both sides of the table have to demonstrate their good will.

The customer can do this being being complementary to the brand and dealer, confirming their desire to drive and stay with the brand.. even commenting about the new cars being released and the hope to test one and perhaps buy one down the road. All of this plays a part in AoA's decision for optional repairs.

Go meet your service guy and explain your view and how you need his help.
