I've had my car for 6 months and have noticed that when I start my car with the vent on blowing air I can smell exhaust fumes. It doesn't seem to happen every time and if I start the car with the air off I don't smell anything. I can turn the air on after ten minutes of driving and the smell is there at first then seems to go away, either that or I get used to the smell. My closest dealership is 60 miles away
View 4 RepliesI have a 2005 Passat and recently I noticed an exhaust fumes smell inside the car; windows closed. This occurs when driving in no traffic... My circulation is on open or outside air...
View 3 RepliesI've got an awd 1.8t and ever since I did my 3" downpipe and cat delete I've had an oil smell both inside my car and from my exhaust. I thought at first maybe it was the valve cover gasket which I did last summer, but it looks to be fine. Also it does smoke out of my exhaust sometimes, but a buddy told me if it was my turbo seals my oil level would reflect the seals being gone, which the oil level hasn't moved. What else could it be? Do I just need to put a cat backin?
View 5 RepliesAfter I start the car, warm up a bit then drive, there are exhaust fumes that get into the cabin as you can smell them.
It's happening more often now. I have spoken to my Phaeton tech who said that the car has a sensor that goes off and shuts down external air if it notices exhaust uses getting in.
I have been hearing a little bit of road noise on the driver side so I'm thinking some fumes are coming in from the door seal (although it looks fine).
Sometimes it's bad enough that you have to open the windows or you will feel sick. It passes within 5 minutes or so and the car is fine after that. It only happens right after ignition for a few minutes.
Why when I come to a stop with the heater on, the car smells like exhaust? I took in into our local Subaru shop and they couldn't find anything wrong. When I'm driving it's fine, but in town or in traffic, I have to keep shutting off the heater. If I forget, the car fills up fumes and I have to drive with the windows down or my daughter's asthma flares up.
View 14 RepliesI have a 2000 Ford Focus ZTS with about 135,000 miles on it with a fume problem. Once it's warm, I'm noticing what smells like exhaust fumes in the cabin when stopped or at low speed (not at highway speed.) It runs perfectly otherwise. I took it in a few months ago (before I noticed the correlation with engine temp), and the mechanic could not replicate the problem, and he said there was no exhaust leak, I now suspect this is because he only tested it cold.
View 4 RepliesMy 2011 Sonata smells like exhaust inside the cab of the car unless I keep the button pushed for "inside air circulation".
I called the dealer and as it turns out, this is a common problem with this model. A hose has to be replaced on the exhaust system.
I knew I was smelling exhaust and also knew there was a problem with the car/exhaust!
Since day one I've had an issue with the exhaust leaking on my car, right at the flex pipe before the cat. I have replaced it at least 5 times in the last year. Every 2 moths or so it tears the flexpipe right in half, like it's literally in 2 pieces when I take it out. So, I thought that maybe the factory dogbone mount was old and weak, causing the engine to move around more, therefore tearing the flexpipe apart, so I got an new dogbone with poly bushings to combat that. It did reduce engine movement, but the exhaust kept breaking at the same spot. Then I thought that the metal was weak from it being welded so many times, so I got a new downpipe with the cat on ebay for like 150 CAN, and put a new gasket on, and now it still leaks...
Only thing though, is that this time on cold starts (as it is winter, so around -25 celcius) its really REALLY loud, like the exhaust sheared off right after the cat. However, after a few hours of driving it seems to get quieter at idle, but if you give it a little gas, it is quite audible. Also I can see exhaust fumes coming out my engine bay on said cold starts, however if I get down to ground level, I can hear it plain as day right where the pinch clamp is that connects to the catback part.
So, my theory is that, cause the bands on the clamp rusted out so my dad just put those u-bolt muffler clamps on there, which I can see an opening in the clamp, even if they're tight, until the exhaust gets hot and expands, kinda making the seal tighter but not air tight like it should. So maybe that clamp isn't doing it's job anymore and I just need a new one. OR it could be that that stupid flex pipe is broken again or that the bolts holding it to the manifold aren't tight, which that can't be cause i got them pretty snug on there. I'll have to take a look underneath again, see If I see any carbon on the exhaust, which would mean a leak, but I checked a few weeks ago and it was shiny metal, no signs of any leaks.
Car is an 04 golf with the 2.0 engine code BEV if that makes any difference. I double checked and NONE of the hangers are broken, and it's held in the right spot as it should, there looks to be no force exerted on the flexpipe at all when installed in the car, so I'm really confused.
My car has an exhaust smell coming into the car; seems to be from in front of the passenger side of the engine. Mechanic said it was from leaking valve cover gaskets, which have been replaced about a month ago. The smell is coming back and getting stronger. When I am in stop/go traffic, I have to open the windows. What else could this be caused by?
View 6 RepliesI'm finding that when I'm stopped I'm getting fairly strong fumes inside the car. Is this unusual? I'd like to have some info before I talk to my dealer.
View 5 RepliesFor weeks I've been smelling gasoline fumes inside the car, usually when the weather is cold and when the car has been sitting overnight; sometimes while it is idling. Have had to car to my mechanic, who I have confidence in and who has done a good job with repairs in the past. He could not locate the source of the fumes.
View 9 RepliesI don't drive this car often. I primarily use it for towing a 6000 lb trailer during the "good" season. I drive it once a week during the off season to keep the rust off and the "blood running".
NOW its got some kind of gas fume issue. No DTC's set. Windows up, fan on low, Nothing on startup. Nothing when driving. I smell it slightly when at a stop light and then it fades away. I smell it strongly when backing up to park.
Almost as if it has something to do with fuel sloshing around in the tank. There is no visible fuel on the ground. But it doesn't take a large amount of fuel to make a BIG smell. Fuel cap is tight. I am averaging 19-20 mpg. (I drive like an old man). Where do I start?
A little background on my Prius, I have an 08 that has around 179k miles on it and have never had any major mechanical problem. I have always kept up with routine maintenance. I use Synthetic oil and change it about every 6500 miles.
So, two weeks ago, it was time to change the spark plugs again. Carefully, I took out the old spark plugs and installed the new spark plugs. On the second spark plug wire and spark plug, I noticed a little bit of oil, so I wiped it off with a shop towel, installed the new plug, and kept going.
Interestingly enough, now I have a problem where when I first start my car (and only when I first start it) and I just have the interior fan running (not with the A/C on) I get some serious extreme exhaust fumes through my A/C vents and that wasn't happening before I changed the spark plugs.
Now my first thought was, "Shoot, what the hell did I do to my car?!"
Here's the weird part, once the ICE has warmed up and shut off for regular "ready" mode, I don't smell it ever again even if the ICE activates as I'm driving. Note that at this point, I haven't made any changes to what fan speed or setting the climate is on.
As soon as I turn my car back off, then back on again by pushing the power button, out comes the awful exhaust fumes again.
So, here's where the testing stage comes into play. I have tried everything I can think of. Yesterday, my father take the air box off and we made sure all of the hoses were attached and the recirculation hose didn't have a clamp. We replaced the clamp and resecured all of the hoses in the engine thinking that there might of been a loose hose with the exhaust recirculation.
I have been getting exhaust in my car cabin since last fall. It is worst when I first start up the engine. Once I get driving, it's not so bad. Switching off the heat or recirculating the air does nothing to change things. I used a CO detector in the cabin and the alarm didn't go off, but it still worries me that I might be breathing in carbon monoxide. And none of the shops have been able to diagnose it, let alone fix it. The first shop installed a new 'flex pipe'. The dealer thinks it's coming from a gasket near the flex pipe. The exhaust manifold is not cracked. A muffler shop said there was no leak. Is it possible that exhaust is somehow getting mixed into the air via a faulty valve or vent?
View 6 RepliesWell I started smelling Gas fumes in the cabin of my 11 GLS. The smell was intermittent for about a month now. Then last weekend it started getting bad. I found it only smelled when pulling fresh air through the HVAC, so it had to be under the hood. Pulled the engine cover to find the foam backing was soaked with gas. Started the car and could see the Hard fuel line dripping.
I saw from other post on the forum that this tube has one time use fitting on both ends and that a special tool is needed to torque the fittings. Dropped it off at the dealer yesterday and they are replacing the line today.
I tell you all this because the Dealer said that their records show my car had the short block replaced at 24000 miles. When replaced they probably didn't torque the line correctly causing it to leak.
The question I have is, Should I be more or less worried about the bottom end of this engine now that I know it has been replaced? The car has 44000 miles on it now.
AC recharge seemed to be when problem started. But... If I do NOT run the AC unit and drive it with VENT open there seems to be no smell. When I run the AC the smell appears. Since the AC system is supposed to be(I think) a closed under pressure system why would I get a gas smell ONLY when the AC is running? Starting /stopping it gets a bit worse. Baffled here but that's nothing new...
View 2 RepliesAbout two years ago, I noticed the smell of exhaust fumes in the cabin of my 2000 Honda Civic any time the vents were set to pull air from outside the cabin. Switching the vents to recirculate would prevent the fumes. Looking under the hood, I found the exhaust manifold was cracked, so I replaced it along with the catalyic converter (actually one piece in this model) and two O2 sensors. Since the replacement, the problem with exhaust fumes remains. I have asked my mechanic to look at this a couple of times, and he could not find the cause. What to try next to diagnose the problem. We use the car frequently, and just have to leave the vents set on recirculate. This becomes an issue on rainy, humid days when recirculate causes the windows to fog.
View 7 RepliesI recently bought a 2003 Hyundai Accent 1.6L DOHC manual transmission hatchback with 124000 miles. So far the work I have done in the car include replacing front bank 02 sensor, new flex pipe, exhaust manifold replaced with a used OEM part. Everything is going great with the car except that the check engine light is on with the P0442 and I occasionally smell gas or exhaust fumes (not sure) while driving and it goes away. My combined mpg is only about 23mpg.
I replaced the gas cap with a brand new OEM part then cleared the CEL. However, after driving 90 miles, it went back on so I brought it to my mechanic who recommended a smoke test. After the smoke test, he said the charcoal canister and the diagnostic module needs to be replaced. Is it worth replacing to fix the CEL code and if the code is related to me smelling fumes inside the car while driving. Also, I would like to know if there might be another problem causing this code instead of the charcoal canister or the diagnostic module.
I have been having an issue with exhaust fumes in my 13 GT (16,000 miles on it). I am positive its from the exhaust. Its definitely the "rotten egg" smell, not raw gasoline. I don't hear any leaks though.
It only happens when going up a hill when the engine is under more load than usual or under heavy acceleration. I am going to call the dealer about it and have them look at it.
I have a 2010 with 5k miles - bought <4 mos.
Last week, I started noticing a petroleum smell in the cabin. I've also had trouble with the inside windshield. When I tried it wipe it, it just smeared. Finally, I used some cleanser and it's clear. It took several applications to work.
I read in the Gen II forums about a loose oil filter cap. I checked mine today. I was able to turn it about 1/2 inch. Now, I'm getting headaches after I drive for more than 15 minutes or so. I've tried switching the circulation but I can't tell which way is better.
Something really strange is happening as I opened the hood after stopping the car the other day and it seems like something is burning ( doesn't smell like oil ) and smoky is coming out from the left side of engine compartment?!? What can it be as I can't see any oil leaks or anything? can something be melting
