Passat (B5) :: CEL On For Code PO456 / Strong Fuel Smell On Fill Up
Mar 8, 2011
Ok, 04 Passat, 1.8T AWM
CEL is on for po456 (very small evap leak) and every time I fill up on fuel, I can smell a STRONG fuel odor, from near the fuel neck, and inside the car. Stops after it hits around 3/4 area. No leaks, and the car runs fine. Gas cap, and N80 valve were just replaced, both parts are from the dealer. I'm going to bring it in for a smoke test soon. All recall notices have been done too, I just did the timing belt.

I have no problems pumping gas in, but the entire car cabin smells very strongly of gas after filling up. It seems to come from the area of the charcoal canister. No dripping of gas, no puddles... Did a smoke test, no leaks showed up anywhere (according to the mechanic). I do not want to start throwing parts at this to fix it - where should I start, and in what order should I throw parts? 2003 elantra GT sedan, 70k ....

Well, finally! After wanting a code to troubleshoot this low gas mileage and fuel smell (outside the car, usually, but sometimes inside the car also) for 3 months, I FINALLY got a trouble code.
Bad news is: it's P0457.
2001 2.7L. Where would you check first? I've already replaced the cap and pump (the old cap was fine). Pulled the EVAP can off today, no holes or anything that I saw to cause a leak. Where is this "two-way valve" located? Think it might be the place to look?

Today while leaving work my car was giving off a strong fuel smell. Wife noticed the garage stunk of gasoline when she got home.
I removed the engine cover just now, and ran the car and checked for any leaks around the fuel rail area, but didn't notice anything.

So I had my sikky headers installed about 3 weeks ago by JE import. Since then they have been a constant hassle by installing a faulty O2 simulator which made me have to get in the car yet again drive to them an hour an a half away.
After another week I got CEL for a second time. After they fixed the faulty O2 sim....
Recently I have noticed a very strong fuel smell while driving. I understand you might get a fuel smell while at a light and the windows are down but I am experience one at cruising speed. I have gotten my car lifted three times in the past week to tighten the flanges connecting to the joeZ as well as checked for leaks (none were found) and there still is this strong smell
I do not want to install high flow cats.

I have a 2007 Hyundai Santa Fe with 83k on it. For some months now, I have always been smelling strong fuel scent in the cabin. I took it to the workshop and was told it's my fuel canister so i handed money to the Mechanic to buy one to replace it. He called back to tell me he cannot get one to but can work on it by blocking the pipes or lines. I am not that convinced because i know the canister is there for a purpose so if he goes ahead to block the pipe or whatever, then it means something else can go wrong in the interim; but I'm in a quandary now and want that fuel scent to stop.

My wife was driving to work today and she called me when she was almost to work and said that when she was at the red-light and said when she started from the red-light the car was fine and she hit a certain rpm and the rpm's dropped and there was a strong smell of fuel. The car was still running and would idle fine but was running almost like it was flooded or had a miss like a coil pack or spark plug. There was no check engine so I am not sure I haven't got to look at the car yet.
I forgot to mention a few months back she had a check engine for the intake manifold runner flap called the dealer and set up an appointment to take it in. Took it up and by the time we got there the check engine was off and car was running fine no issues. They said no sense in bringing it in now just set another appointment if it comes back on which it never has and still isn't on but I am wondering if this problem is related to that? I know for sure that the car is still covered under the enhanced warranty for the injectors and intake manifold.

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?

I have a 2007 Santa Fe. If I fill the tank to full, or close to full I will have a fuel smell in the car until the tank runs under 3/4. If I keep it under 3/4 I usally do not get the smell in the car.
The dealer could not figure it out and I still have this issue. It seems the smell is more in the front of the cabin then the rear. It just could seem that way since the smell is very strong. I have to park the car with the windows open.
There are no fuel leaks, no fuel on the ground, no drips, and the no spillage when I filled the tank.

My dad's Camry (which I also drive), has been having a problem since a couple of months now. Whenever I floor the vehicle, you can feel the power kick in but after a couple seconds you can feel a slightly lack of power. Its not like the car doesn't accelerates, but it does feels like if you release the pedal a bit.
The car also has the following issues:
-Shifting problems: The car has been having shifting problems due to the automatic transmission fluid temperature sensor (don't know if this may cause the ecu to go in some sort of "emergency mode" and reduce the power a bit)
-Strong fuel smell after driving: After some driving, you can smell fuel mainly at the back of the car.
I'm thinking in about changing the sparkplugs as we have never done it to the car. Car has 80.000km (50.000 miles) Car is a Toyota Camry 2007 V6 3.5 2GR-FE

I have a 2002 Oldsmobile Silhouette which has been a great car, but due to its age has had some issues in the past year. The most recent is that it does not start well. When I turn the key, it chugs but I have to push the gas to get it to start and then there is a very strong fuel smell. We had it "tuned up" recently, but that did not work ( in fact the starting has gotten worse).

On a recent long drive home through some very hot weather, I noticed a strong smell of gas at the back of the truck. Now, I've caught a whiff of gas before the trip but it was always faint. Figured it was some gas that dripped on fill up.
At a rest area, I go and look around see no leaks and finally check the fuel cap. Lots of pressure trapped. I ended up leaving the cap off the rest of the run home. Can't find a cause.

After the upgrade to APR Stage 1, there is a strong Gas smell in the car. The APR dealer indicates that this is normal (expected) due to the additional boost.
Is this correct. DO all of you who have the APR upgrade have a gas smell in the car? The car has a stock exhaust.

03 Baja, 4cyl, automatic. 195,000+Every now and again I get a fuel smell. Full tank, empty tank, half a tank... doesn't seem to matter. Usually switching up the gas I put in clears the issue. This time, not so much. Really strong and causing me to banish the car for the garage due to it stinking up the house.The odor MAY be coming from the left/drivers side of the car. (I only say this as if it is outside in the parking lot, I notice it more on that side.

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?

There is no noise that would indicate a hole in the muffler, just the exhaust smell. I'm wondering if the catalytic converter is going out? If it is the catalytic converter, will it strand me on the highway eventually?

Having a strong odor/smell in there car after service at the dealer? I have a strong smell as if someone sprayed an aerosol can in the car or a marker was left without the lid on it. It has been 2 days since the service and the smell is still there. I called the dealer and they said they would take a look at it, but they didn't know what it would be. I though it might be the adblue since they did refill it, but I don't think that stuff has this strong of a smell and the filler is in the trunk area.

Its a 2009 Prius with about 75K miles on it. I have scangauge on the dash as well as mini-VCI. It is setting PO456 code time after time. I reset it, but it comes back in about 50 mils of driving. Its not the gas cap, I turn it until it clicks every time. Something is wrong with evaporative emissions system, which I wouldn't care about, except it might mask some other fault code that is more serious, as it keeps check eng. light on all the time.

This is my first car with leatherette, wondering if that is causing the smell? Its not the monster mats. I have had several new cars and this is different than the average new car smell. Looking to getting rid of it?

Yesterday, after having driven the car twice, I got in it to move it, and it would not start. It almost turns over, but never reaches a start, until the dash prompts me to to STOP. I also notice a stong gasoline smell when I get out of the car. What this might be?
