Passat - Volkswagen :: 2005 - CEL Came On / Faint Exhaust Type Smell
Jun 15, 2015
CEL came on. No performance issues or noises coming from the car this time around. I did notice that after parking and killing engine, there is a faint exhaust-type smell though. I took the car to my local Advance Auto Parts and had them hook the car up to their computer for a diagnostic. Two codes came up.
1: P0431, warm-up catalyst efficiency bank 2 below threshold pending
2: P0431, warm-up catalyst efficiency bank 2 below threshold confirmed
The AAP employee didn't have anything to add to the code readouts. I'm concerned that this is a catalytic converter issue, and if that's the case, a repair would likely cost more than I'm willing to put into the car at this point. It has just over 125K miles on it.

My 2003 Passat has a noxious smell when I pull up to a parking space or sometimes when I stop at a light. It smells like burning oil or exhaust, but not all the time. The repair shop has replaced the oil pan, which was dented (by my 18-year-old son), replaced axle seal, and have replaced a broken and leaking PCV hose, but that has not solved the problem, and the don't know what else to do.

I have a 2009 nissan rogue that when driven for 30 minutes or more with the ac on leaves my clothing smelling like exhaust (faint smell). I have had the dealership look at the car and they cannot find anything. We have replaced the interior cabin air filter and I still find the smell. this is not something that I notice while driving until I have been in the car for 30 or so minutes. My wife also notices the smell in her clothes after driving and now won't drive the Nissan. We are running the car with maximum AC turned on with the air recirculation button on as well. SO, theoretically, no outside air should be getting in but it still seems like our clothes smell like we have been in a traffic jam with the windows down after 30 minutes of driving.

2000 Nissan Sentra with 105,000 miles. Runs great. All scheduled maintenance from the beginning. Grandma owned until I got a hold of it 2 years ago.
The beginning...
The car has had a slight exhaust-type smell for about a month. I thought it was either an exhaust leak or a small oil leak. I overlooked this as it was running great and I only drive to and from work at a total of 5 miles/day. I was going to be driving it about 20 miles so I figured I should just double check the oil.
Before my drive, I checked the oil and the dipstick said I had absolutely no oil. Backstory: I got my oil changed about 2 months ago and they broke the dipstick. They replaced it with a new one. I drove a few blocks to get oil. I purchased 2 quarts filled it up. I drove off and about a half a block later it started smoking bad. White smoke canvassing the whole street.
I turned around and went back to the auto parts store. I had a guy come out and look at it and he was baffled. The only thing he though was that it had run completely dry and it need more oil. We put 2 more quarts of oil in it (4 now) and it did not register at all on the dip-stick. A small oil leak was discovered coming from the head gasket (that was the smell). Also, there was no milkiness under the oil cap indicating
I decided to drive it back to work to leave it overnight. It smoked like hell and I made it about 4 blocks before it died. I pushed it the rest of the way and it stayed overnight.
The next day, I spoke to a mechanic friend. The only thing he could think of was that the dipstick was not the right size and it wasn’t reading any oil. The oil I put in was extra and the car was burning it off. He suggested I drain out all the oil and put 4 quarts in.
I drained all the oil but only 4 quarts came out. I added 3 quarts of oil and checked it again. Not it was reading about 10 times more oil than what I was supposed to have.
My mechanic friend said to start it up and the oil level should go down. I did start it up and the oil level did go down but it was reading about 5 times more oil than it should have. That is where I am at at this point. Hopefully it isn't a blown head gasket or piston.

I just had a blown motor swapped with a used engine with around 50,000 on it in my 2002 Toyota Camry LE 4 cyl.
After driving the car enough to warm up I turned the vent on and in comes a fairly strong exhaust type smell.
I have driven the car for a little over an hour since the motor swap.
The car is driving fine with plenty of power and no sputtering or rough idling.
I just called my mechanic and he seems to think it is due to the oil that is present on/around the motor/exhaust from the swap that is burning off.

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...

I just got a 2008 Passat and have noticed that after I start the car, for about 10 seconds, I can very faintly smell coolant, it happens when the fan is off or on, and the temp is either on hot or cold. Its not bad, but it is there for short time.
It reminds me of how my older VW's would have a bad heater core, but even that was only noticeable if the heat was ON, this happens heat on or off. Also I see no leaks in the engine of any sort, the car only has 150 miles on it currently.

I'm having a strange exhaust leak type noise (loud exhaust type noise like hole in exhaust pipe) that goes away after about 20-30 seconds.. quite noisy in the garage. Can't see anything obvious. I tried the dealer but they always send a porter to bring the cars to the service bay and of course it stops by then! They couldn't duplicate the noise.

About a month and a half ago, I took my 2005 Honda Civic LX to a mechanic for an oil change. He informed me that my air filter needed to be replaced as well, so I told him to go ahead and do so. Ever since I got the car back, however, I've been smelling car exhaust unless I push the button for recirculated air. What could be causing this?

I have a 2007 Passat turbo wagon and my cat converter got a hole in it the other day. I drove in morning and it was just noisy otherwise fine. My wife took it in afternoon and almost didn't make it home. Could hardly make it up a hill and brakes had to be applied to floor. Anti lock would vibrate but not very responsive to stopping. Was towed to local mechanic next day and he thinks problems are related. Could the computer cause a breakdown of the brakes due to bad exhaust system? He says he can't find ant leaks in brake system. He is waiting for the cat converter to come in to replace and hopes brakes will work again.

Just put a dual flowmaster exhaust on my truck, a week later my engine light came on. I also smell a sulfer smell and the truck seems to sutter when in gear at a stop, and also hard to start at times. What this could be!

I have a 99 Passat wagon. After I got hit in the left rear quarter panel, I started detecting exhaust smell in the car when I opened the windows or sun roof. The exhaust pipe did not get damaged, but neither the body shop nor the regular shop could detect anything out of the ordinary. My theory is that the new bumper cover may be a little different than the one that was on there and does not let the gasses flow past the bumper the way it was before I got hit.

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?

My 2001.5 Passat traditionally does not start easily when it is less than 6degrees outside. Today it was that cold..it started easily..but about 30 minutes into my drive to work..I realized it was a little smoky and exhaustish smelling in the car..once I realized it wasn't the car next to me..i realized if I turned off the heat..the smell went away..but at the stoplight..i could see smoke coming from under the hood..out the corner by the passenger/dashboard... Car has 80,000, recent oil change, what it is?

When I run the heater on high to be directed through the dash and foot areas here in Wisconsin, I receive wonderful heat from the dash, but ice-cold air to the feet. What is going on? Do I have a clogged heater core or line? Or could this be an easy fix I could do myself?

My daughter drives a 2005 Passat station wagon, has a small child and one on the way. She has had intermittent problems with the car just not wanting to crank. After sitting 15-20 minutes it will crank. But the wait and not knowing if it will crank is taxing me and her. Especially since she has another one on the way. She has taken it to a reputable mechanic. They kept it for 3 days, cranking it on and off without a problem, and told her they couldn't find anything.

I have a 2004 Jaguar X-Type 3.0 that I use as a daily driver. This morning, when I got in the car I immediately noticed a strong smell of gas. I've had an empty gas can in the trunk for a couple days so I wrote it off as being due to that and expected the smell to dissipate after a bit. I turned on the A/C and the smell only got worse. Obviously I've got a leak somewhere, the weird thing is that the engine bay doesnt smell at all and I'm not able to smell it when outside the car. I plan to take it in to get looked at (my poor wallet) but I'd like to have a good place to start.

I own a 2005 Volkswagon Passat, and took it to my mechanic yesterday to get a sticker and my new summer tires put on. When I picked up the car, the passenger side speaker is no longer working. About a month ago I took my car to a specialist to have an aftermarket radio put in for me that I got for my birthday so I can listen to my iPod. Why my passenger side speaker is not working anymore? Does it have anything to do with what my mechanic might have messed up when putting the new tires on?

2005 VW passat... I bought this car used. I was told the front engine mount needed to be replaced. When it was replaced, the vibration began. The mechanic used an after market mount. He replaced it with a VW mount and also replaced the two side mounts for the transmission with VW mounts. The vibration was still there. I then took it to a VW dealer and they confirmed that the mounts were installed properly and could not identify the cause. I took it to a third mechanic who made some adjustments to the front mount and that reduced the vibration somewhat. After a few months, the vibration increased and I took the car to another VW dealer. He said the front and side mount needed to be replaced. That was done and still the vibration continued. What else could be going on to cause this problem. Carfax indicated no accidents or body repairs.
