Phaeton :: Exhaust Fumes In The Cabin - Can Feel Smell
Feb 10, 2012
After 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.

I 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.

From time to time, i get some exhaust smoke smell in the car, when driving slow or standing in a queue.
90% of the time everything it's perfect, but at a sudden moment, the rpm is rising with 50 or so, the instant consumption rises from let's say 1.4l/h to 1.8-2.0l/h when in gear and standing, i get a small vibration and then the exhaust smell appears.
If i'm closing the recirculation, then no more smell.
After 15-20 min, everything get back as it use to be, 1.4l/h consumption, no vibrations no smells no nothing.
This i think happens when the dpf is cleaning and i cought with vcds of a friend when it happened and the exhaust temp was 350 celsius or something. Usually is 200 degrees celsius, so it is a dpf regeneration. Also the car is running smoother after this.
Still..the smoke smell... it's annoying and quite strong. There is no sign of smoke from the exhaust pipes, flexible pipe or whatever. There is no sign at all anywhere.
I have a small theory but i don't know from where to start. Usually the catalyst temp is 200 degrees. When it's 350, it expanding more, or at least the cracks are expanding and smoke+smell is from there...but there is no sign anywhere.

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?

Well 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.

About 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.

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.

Newly acquired 2002 Accord.
At idle and while at a stop, the cabin receives a heavy dose of exhaust fumes (nope, not from the auto in front of me - I'm often alone at stop lights/signs)... what is the most likely culprit?
This did not seem to occur until AFTER I had the timing belt (package) replaced...coincidence

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

I 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...

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.

I just got my 2000 Passat back from the body shop. I rear-ended an SUV about a month ago and had my hood, front bumper, left headlight, A/C compressor, and radiator replaced.
HOWEVER, now when I let 'fresh air' into the cabin, I smell a strong exhaust smell. When I push the 'recycle air' button, the smell goes away. This leads me to think that somehow my exhaust pipe was cracked/damaged in the collision and is now spewing exhaust gas into the engine compartment - and thus when I allow fresh air (front the engine compartment) into the cabin...I am getting toxic exhaust blown in my face!
Where should I look for signs of an exhaust leak and is there an easy 'trick' to find the leak?

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?

Gas / Exhaust fume smell ... in the cabin? I've been noticing I smell like I've been in an old school muscle car running straight pipes every time I take the car out. More of an exhaust fume smell but sometimes the fresh gas smell is very strong.

I have a 2014 RX 350. I have noticed an intermittent issue with exhaust smells coming into the cabin when the car is on recirculate and I am at highway speed. It happens when I am first accelerating after I've entered the freeway. If I get the odor, I can make it go away by briefly hitting the recirc/fresh button to bring in fresh air for a few moments. This doesn't happen driving around town.

Driving along last night and suddenly slightly oily smell in cabin. Then notice oil pressure drops from normal 82 ish to about 25. Recovers to about 70 by time I get to Waitrose (about ten mins). Park up and do shopping. Move car and check for oil patch - none found. Drive home and pressure still lower than usual - but recovers to just under normal. No warning lights - open oil filler cap and seems to be some in there. No oil leak found.

'90 Maxima 256k.....recently I've noticed exhaust coming in through the vents when I have the AC on and have been idling or driving in slow traffic. I know I have a small exhaust manifold leak because I hear the clicking. The problem is this exhaust smell happens very intermittently. Usually on hot humid days when I have the AC on. I have tried to duplicate the issue to no avail. Sometimes I can sit in a parking lot at idle with the AC on for 30 minutes and I don't smell any exhaust (not even when I smell under the hood). How can this be? If it truly was an exhaust leak then it would leak all the time and I would smell it. Could my EGR valve be leaking? When the EGR valve is activated?

Mechanics are stumped. 3 months ago, during a 4WD commute through the snow, I started noticing what at the time smelled like bus exhaust coming into the cabin. My SES lights comes on for 2-3 days, then off for 2-3 days. Codes say MAP sensor and low coolant coolant.level. When the SUV warms up fully, you can smell the odor strongly under the hood, inside the cabin while sitting at a stop light, and inside with the Heat or AC on. Mechanics had the car for days, replacing cam and Map sensors. There is no evidence of exhaust leaks or coolant on the engine. Level of coolant has been dropping slowly in the reservoir.

I have always had a occasionally burning smell in the cabin when I am using the heating system. Has never happened in summer. Only happens randomly in winter when I am using the heat. I don't think I have seen steam and stuff and definitely no water puddle in footwell area. This strongly makes me think that I have a leak in the heater core area, maybe not the core itself, just o-rings and things like that. Vw has checked many times and replaced the valve gaskets. But the smell is still there. This morning when the smell came, I opened up the hood immediately and I think the smell was around the passenger side plenum chamber area.
