Touareg :: Ticking Under Heavy Acceleration And Strong Smell Of Exhaust In Cabin?


Jul 5, 2005

Not long ago my wife said the air recirc doesn't work any more on our '04 V8 and I had to admit that I agreed. After a little investigative driving, I noted that heavy acceleration (or uphill climb) causes V8 to tick (can hear it reflecting on passing walls, for instance) and strong smell of exhaust in cabin.

I thought it might be a manifold/exhaust system leak causing the noise and the exhaust smell. Seems to be only when driving aggressively or climbing. Soonest the local dealer can see it is 7/21 (16 days from now). You think it safe to drive?

Passat (B5) :: Strong Exhaust Smell Around The Car And In The Cabin Except When A/C Is On

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?

Camry :: Strong Exhaust Type Smell In Cabin After Warm Up And Vents On

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.

Touareg :: Exhaust Noise Upon Medium To Heavy Acceleration

I have noticed since day 1 of owning my v8, that there i a horrible sound that comes from the exhaust upon medium to heavy acceleration - a loud fluttering is the best way i can describe it. I took it to the dealer and one tech said something was definitely wrong, the other went and got a new reg off the showroom floor and demonstrated that it is common and normal. Although another new reg did the same thing, i am not convinced that this obnoxious sound is normal ...

Santa Fe (CM - 2007-12) :: Strong Fuel Smell In Cabin

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.

Lexus LS 2007+ :: 2009 LS460 - Strong Gas Smell In Cabin And Around Gas Tank

Yesterday afternoon, after a 90 minutes stop and go commute, a strong gas smell developed in the cabin of my 2009 LS460. The factory call-back service was performed on the car few months ago.

During yesterday's long commute, the LS460 passenger side wheels run over some garbage on the high way at high speed, and after that I can hear some noise from passenger side, sounds like a flag's flopping sound.

Other than that, recent incidents that I can think of that might be related are:

1. All 8 control arms of front wheels replaced about 3 weeks ago
2. Have been using Sam's Club premium 93 gas for the past 4 weeks

Golf/GTI VII :: Strong Odor Of Windshield Washer Fluid / Cabin Was Filled With Smell

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.

Ford Wiring/Electrical :: All Gauges Stopped Working / Strong Burning Smell Inside Cabin

My father in-law gave us a 1996 explorer AWD with a 5.0 for my son who is 16. A couple of weeks later he's out learning with my wife and a very strong electrical smell took over the cabin. They came right home and when I got in I found all of the gauges not working. The instrument lights work, blinkers work, but all gauges do nothing. Pulled cluster and wires look O.K. behind it from what I can see. They saw no smoke, just smell, fuses look O.K.. What could cook on this vehicle that would wipe out just the gauges?

Elantra MD (2010-15) :: Intermittent Strong Exhaust Smell

I'm going to take my Elantra in to get it checked. My Elantra is a 2013, got it in March. Over the last few weeks, I would say, on 4 days or so there has been a STRONG exhaust smell. No smoke, nothing else but a smell. If I'm pulling into the garage with no idling, just pull in and park, I get out and the smell in the garage is very strong. I have to leave the garage open for at least an hour if not more to air it out. The cab ends up having a light smell inside the next day still.

If I'm parking outside when I get out I can still smell it, but not quite as strong, because I'm not in an enclosed area. I don't think it's an exhaust manifold leak, because I don't hear the popping. My best guess is it would be in the tail pipe area pre-catalytic converter, or in the catalytic converter if it is in fact an exhaust leak.

Jeep - Liberty :: Strong Exhaust Smell Coming In Through The Vents

For the last few months, I've had an annoying problem with my 2003 Liberty. If I'm driving the car with the blower on (i.e. when it's cold out), whenever I stop the car and am idling, I get a very strong exhaust smell coming in through the vents. If I turn the fan off, the smell goes away. At first I figured it was due to being behind other vehicles, but now I've noticed that it does it all the time, even when there's nobody else around.

I brought the jeep into a shop a couple of weeks ago to deal with a separate CEL issue (evap leak - fixed by replacing gas cap) and I asked the mechanic to look for an exhaust leak. He said he didn't see any readily apparent problems with the exhaust line.

I'd like to deal with this because it's not very pleasant to inhale exhaust fumes through the vents. I intend to take it back in - but is there anything I can tell him (i.e. like, a particular part of the exhaust system to inspect more carefully) that will solve the problem?

Impala - Chevrolet :: 2011 - Strong Sulfur Smell Coming From The Exhaust

I purchased a 2011 Chevrolet Impala last year with 14,000. When the car reach 26,000 I begin to smell a very strong sulfur smell coming from the exhaust. I took the car to the local Chevrolet dealer and was told that the particles in the catalytic converter begin to break up at about 26,000 mile and the result is a sulfur smell.

I didn't believe that all Impalas had this problem. So I took it to the Chevrolet dealer in the next town where I personally know and trust the maintenance chief. He put his two best men on the car and could not find anything wrong. I was told to try another gas station which I did but it did not work. I now have 31,000 miles on the car and the smell is very strong coming into the passenger compartment when stopped.

Sonata I45 (YF - 2011+) :: Heavy Fuel / Exhaust Smell

My car if left on in park for 3-4 minutes starts to have a heavy smell of something... Is my car running a little rich or is there a more serious underlying problem?

RPM of car idle is 750.

And car doesn't smell like fuel when I'm driving, only if I leave the car running for a while and it sits there does this smell begin to build up.

Passat (B5) :: Exhaust Smell In Cabin - Possible Causes?

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?

Grand AM :: Car Running Rough With White Smoke And Strong Gas Smell Coming From Exhaust

My car was running rough, with white smoke and strong gas smell coming from exhaust. It died out on me a few times as if it was not getting enough acceleration. Well, I coded it and said misfire cylinder 3 and 4. I also tried to shut down 3 and 4, but did not shut down. I switched 3 and 4 with 1 and 2, still did not shut down cylinders 3 and 4. Engine coils are good, engine module was tested and passed twice. Ok, fuel injectors 3 and 4 were leaky and I changed them out. New spark plugs and boots. New oil and filter..(There was gas in my oil and oil in my air filter.) With the new parts....my car sounds soooo much better!!! still a little rough, does not bog down, but it still has the strong gas smell and white smoke from exhaust..(gas smell soo bad I had to open all doors to the garage!!) What else could be wrong?!?! I'm getting frustrated!! It also has NOT ever over heated, does not run high.

Ford 6.7L Power Stroke Diesel :: Strong Exhaust Smell On Cold Start?

We've had a run of -20 to -40 weather here for the past few weeks.

A few weeks back I noticed that when I climbed into my truck after command-start warm up for 10 minutes, and I could smell strong exhaust.

I figured it was hopefully the wind, or an isolated event.

Over the past few weeks I've used my truck for 3-4 more around town runs and every time I warm it up I get the strong exhaust smell. It's that rich, eye watering, sickening exhaust smell. I also notice a small yellow frozen puddle under the exhaust tips that wasn't there before.

It's bad in the cab, but even walking around outside the truck and the smell is sickening. I actually just started the truck and I could actually smell the exhaust smell faintly, from inside my house! This has never before occurred. Prior to this, a person could hardly tell it was a diesel by the smell of the exhaust.

Once the truck is up to temperature the smell seems to disappear, or at least lessen.

Ford Ranger / B-Series :: 1994 - Running Rich / Strong Exhaust Smell

1994 reg cab 4.ol 13ok.. my wife just got it, been doing some small things like replaced dome light, replaced cargo/third brake light, truck starts and seems to run ok. but i get a headache in it which i believe is carbon monoxide, has a leak or something? i text previous owner, he said he replaced 02 sensors, but didnt say if they were bosch or a good brand.. also trucks has a oil pressure and coolant temp gauge fitted on by the gear shift as the dash gauges for those functions are out. Does this mean the CTS may not be working and affecting fuel/air I do not know these trucks i only just found out what this strange silver looking thing was it is the IAC, I Believe, then there is this black plastic vacuum type cylinder by the passenger side firewall, what is that? and right against the drivers side fire wall is a small reservoir type thingy, is this something to do with ABS? i do have an ABS light on, was hoping it was the bulb out on the third brake light or something quirky like that no such luck its still on after starting engine. but i am concerned about this running rich/strong smell as we really cant take it far as is it, its dangerous, may have to get a smoke test? Just got the truck, trying to get caught up..

Phaeton :: Exhaust Smoke Smell In Cabin

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.
