Passat (B5) :: 2002 GLX V6 - Gas Leak And Strong Odor
Aug 26, 2012
Car: 02 Passat GLX V6 4motion
Mileage: 99k
Just recently bought this car (3 months ago) and I have had lots of issue with it already. I topped off the tank that same week and it started to leak gas right under the gas tank (driver side in front of the rear wheel).
No engine light came on. It leaked for couple of days for about an hour after I park the car then it would stop until I drive again. It did that for couple of days until the gas level went down to 2/3 then it stopped. Since then I stopped topping it off and it hasn't leaked.
However I always smell gas even when its not leaking. When I go around the car the odor comes from right in front of the rear wheel (driver side).
Prior History: This car was rear ended before and fixed up by the prior owner. The seller told me that he had recently replaced the fuel pressure regulator that week.
I took it to the mechanic and had them do a smoke test. They couldn't pin point the leak so they recommended replacing the entire fuel tank for $1800. I walked away and thought I would just keep the fuel level low and keep driving. However the gas smell really bothers me because the car is parked in the garage and the gas odor builds up to unbearable condition.
What could cause this issue? Does this has anything to do with fuel pressure regulator that was replaced? Anything to do with fuel pump because of the rear end accident or loose seal in that area? Do you think it is necessary to replace the whole tank for this?

I let my sister borrow my 1995 4 banger Ford Ranger for about a week. To make a long story short, when I drove it home I could smell a really strong gas odor so I pulled into a gas station and noticed gas pouring out of from what looked like the fuel filter area right under the driver's side.
Anyway, it took another 5 gallons to get home and I later crawled under and took a look. It looks like someone grabbed the fuel line and tried to unsuccessfully pull it out of the fuel filter by hand. I could literally see the imprint of the person's hand where they grabbed the line. They had pulled the line so hard that it crimped and split which is why gas was leaking like a water hose.
I picked up a Ranger specific Dorman fuel-line repair kit from Advance and had my brother install it for me as I'm no mechanic. It was fine for a few days and then I started to smell gas again so I crawled under and took a look. There's just barely a small leak coming from the connector barb/union on the kit. Anyway, I didn't know what else to do so I dropped the Ranger off at a local shop this evening. With that said, this is fixable, right?

I have a 2014 TDI with 86,000 miles on it. Several weeks ago I had the heater core changed and since then the car has ran hot twice when what appears to be a regen. The heat has stopped working again. When it is running hot, I can smell a strong odor of ammonia. It does not run hot all the time. Last time it ran hot, I felt the radiator and it was not hot all over. The passenger side hose was not hot and the top of the radiator was not hot. I have taken it to the dealership several times.
At first they said that they thought that the thermostat needed changing. I declined and said that it would run hot all the time with a bad thermostat. The last time I brought it to the dealer - I stated that I think the radiator is clogged. Now they are indicating that they want to change the radiator, thermostat, heater core (again), and flush the system. The system has been pressure tested and no leaks have been found. The tech indicated that it ran hot while in the shop with the A/C on and it boiled over.

I have leased a new Hyundai Elantra Limited 2012. We have noticed a very strong odor in the trunk. We have removed all the trunk mats and spare tire insulation trying to air them out and the smell still persists. It smells like something is burning or has burnt near the wheel wells or the back fold down seats. How to get rid of it?

I have a rernote starter installed on my '07 SF 3.3. It will leave the engine running for 18 minutes before shutting off. If I get into the vehicle after it has been running for over 10 minutes or so, there is a strong odor of gas inside.
Where I might look for where it is coming from? If I remember to leave the vehicle in "recirculate" mode the night before, the odor is less, but my wife and I drive it equally so often the recirlcualte button will not be pressed.
Not sure if there is a leak somewhere (no other signs of a leak or gas odor while driving), or if this is "normal"...

Over the last 2 days here in NJ were its been cold. When starting the Treg and get out of the car I smell a strong odor of gas from the Exhaust. This normal? Haven't had this smell before. Seems like it drives normal. Don't get to drive it everyday anymore. Only on weekends as my wife take the Treg to work now.

I have a 2007 Santa Fe GLS with about 68k. Starter her up this am and smelled a very strong odor of gasoline in the cabin. I check my garage floor and didn't see any leaks. Drove it for a few minutes and the smell went away. What might be causing this?

I remember reading very recently about someone who found a fix to the strong fuel odor on cold starts. I can't seem to find it anywhere. I think it mentioned something about a bad ignition coil or something.

I have a problem that I cannot pinpoint. For at least 2 months now, I have noticed a strong odor almost like a diesel coming from the exhaust. I replaced the plugs, wires, air filter and cleaned out the throttle body but it remains. No check engine light and runs smooth. Also, noticed a significant loss of coolant from the overflow bottle. Filling it every 3 days. Took it out to inspect for holes or cracks and nothing. Not sure if all these are related. Every oil change the used oil smells like fuel. I was thinking rings going bad but don't think that would solve the coolant loss which is unseen. Everything under the hood is dry.

I changed the gas cap on my car. This did not change a thing. I took to i believe reliable mechanic (has worked on car several times) and was told it is bad leak from the "sending" (I think) tube. I think it is the plastic? thing that sends fuel to the fuel pump. This is cracked.

I have a 2010 Prius and it has developed a very strong mold smell/odor. It is strongest when the car has been sitting with the windows up. I have tried many of the tips in the forum regarding not using the recirc mode. I've clean the car inside and out, mats, carpeting, every compartment.
I have talked to the dealer parts counter and replaced the cabin air filter with the carbon filter and used the 2 can treatment that Toyota sells (one in the a/c drain x2 and the other in the air intake.). No joy.
I took it to the service department they did the same thing - again, no joy.
They have asked me to bring it back for, and I quote, "exploratory surgery." I asked if this the covered under the Toyota Certified Warranty. He could not confirm that it would be covered.

Has encountered a strong odor of washer fluid when using it on your windows. I was driving to work this morning through a snow storm and needed to use my washer fluid for the first time. As soon as I turned it on the entire cabin was filled with that smell. Could this be a leak?I thought it was all confined within the engine compartment so not sure why I smell it immediately upon using.

When I fill my tank with gas I get a very strong odor of gas throughout the vehicle, what do I need to check to fix this?
Also this one is weird, but everytime I make left turns ONLY, my Jeep does a down shift but stays in Neutral longer than it should but then kicks into gear by me taking my foot off the gas pedal and reapplying. What this could be? I have made sure that my Transmission levels were fine but I am baffled what the problem is?

I have been smelling fuel on and off for the last few weeks. I thought it was the fuel bowl drain valve so I ordered the kit for the whole fuel bowl from diesel o-rings. I did the rebuild this morning and I don't see any visual leaks. Still smell a strong odor of diesel though. The lower engine cradle is all wet and the valley is still a little wet too. Could I still have a leak and if so where to look? Could it be just wet still from draining the fuel bowl and needs time to go away?

Lately I have noticed an intermittent strong overheating odor coming from the rear passenger tire area of my 1999 Sonata. I was also beginning to notice the car vibrating or riding unevenly. I took it in to Les Schwab to have the brakes checked and was told they were fine with over 50% on all four brakes. I did have the front tires replaced as they were worn and wearing unevenly and was told this is what was more than likely causing the vibrating. That was a couple of weeks ago and I had not noticed any odor coming from the wheel well until yesterday the minute I opened my car door after driving home from work there was the same strong toxic smelling odor coming from the same rear passenger wheel well, but not from anywhere else. I have only noticed this smell after driving home from work and there is a fairly steep hill I go down not too far from my home. Is this a brake issue or something else?

In December, I took my 2001 Ford Escape (123,000 miles) to my mechanic to find the source of a burning odor that I'd been smelling after driving. My engine light had also gone on several times and the engine ran rough, especially after very wet weather. They attributed the engine light to a cylinder 4 misfire, and the smell to oil leaking from my valve cover gasket. They strongly recommended, due to the proximity of my coils and spark plugs to the valve cover gasket, that I have my (still original) spark plugs and coils replaced in all 6 cylinders.
Considering that one coil had already been causing problems, they said that it would save labor to do them while they were so close in proximity. Considering the age and mileage of my car, the fact that I'd like to keep it for a couple of years, and the fact that this is a trusted mechanic, I took their advice. I had all of these repairs done to the tune of 1800.
Following this repair, I still smelled the burning odor. I gave it a couple of weeks, thinking this may be recently-leaked oil burning off, and then brought it back to my mechanic. They could not easily identify the location of the leak, so they injected dye, and I returned a few days later.
Now I'm being told that the oil leak is from my timing cover gasket. In addition to that, they say that the oil pan gasket will need replacement, because of its proximity to the timing case. My valve cover will also have to be removed and possibly replaced, but they said that they can possibly reuse it since it was just replaced in December. There was some discussion of replacing the timing chain while they were in the case. As an aside, I have had no indication that my timing chain has any issues.

I have an Oct 2001 2.7 GLS which apart from the odd ABS Tone Wheel and speed sensor issues has been uber reliable and a real pleasure to own (I've had it from new).
We had a problem about a year ago when the wife didn't get the fuel cut-off when filling up and over filled the car resulting in fuel pouring out of the tank vent and down the fuel tank under the car but after a long drive that cleared up and has not happened again. Interestingly we didn't get any engine CEL's or have any codes turn up at all when checked by my mechanic.
Over the past couple of weeks we have noticed a very strong smell of fuel under the car around the fuel tank. I can't see any indication that there is a fuel leak but have noticed when filling up that the smell is very strong and as the car runs the fuel down the smell reduces to almost nothing.
Today I removed the rear seats and the fuel pump access panels to see if there was any seeping around the pump gaskets but couldn't see anything and the top of the tank around the both pumps was a dry as a bone. Using a torch I did however notice that there was a darkening of the fuel tank surface in the centre which I guess is close to the vent valve, part 311990b:
Or maybe is where the fuel vent pipe runs to?

My 2002 6 cylinder Malibu gives an odor of gas when turning on the heater it has had a fuel pump and filter install 8 months ago and there has not been any smell until I used the heater this winter. I understand fuel consumption is more when using the heater but this is ridiculous I go around 8 or 10 miles and i've used more than a quarter of a tank.
