GTI 337/20th Anniversary :: Strong Gas-like Smell Coming From Engine Bay?
May 14, 2012
I recently had a turbo installed, everything went well, car runs very smooth considering having just upgraded the turbo. However, I keep noticing a strong smell coming from the engine bay. Kind of like a gas like smell or some chemical. At first I thought it was the loctite we used to put the gaskets in place burning off or the coating of the turbo but it has been a week and it still smells. I do not have a check engine light, my vacuum is right on the money, I am boosting fine, and my temperature gauge hasnt moved. What could this be? exhaust leak maybe?

Lately I've noticed an exhaust smell coming into the car when idling. Could it be an gasket. Car doesn't sound different at all or anything.

I got my heater core replaced about 2 months ago. Since than I get this almost like a burning smell coming through the vents. Took to dealer they said they dont know, because i replaced cabin filter, and they say they don't smell a coolant leak. So to find out they have to take apart my dash! Comes through when the car heats up/ or i turn on heater.

For the life of me I can't figure out what is causing this smell. Its got a little over 65k miles and for whatever reason when I'm driving at a steady 70-75mph on the highway I get this garbage like smell that can last between 2-6 sec or so with or without the a/c on. It appears to have no effect on the car though. I'm not overheating, I'm not losing any power from the motor, my clutch is still very smooth and no signs of slipping, my idle is solid as a rock, and I can't find any fluids leaking at all. It does seem to happen more frequently as the outside temperature increases and it is a very potent smell. I just can't find the source. It has only happened while I'm on the highway and have had absolutely zero luck finding that same smell when I've got it parked with the hood up.

I am hearing a rumbling noise when I hit 4000 rpms on all gears worst in 2nd and 3rd.... I just recently replaced the timing belt, TBA Done, valve cover gasket, and passenger side axle (through raxles). Anyways I started hearing noise after those repairs, my mechanic has gone through all the work recently done and cant find the problem..... We replaced the tranny mount thinking it was that, but no luck.... I have not lost boost, and noise starts 4000k and goes away at 4700k No codes are flashing.

Car was started for the first time after the radiator was flushed and new coolant was put on it. The car was just jumped and charged after was brought from a copart auction. Now my brother said that everything looks smooth, no xxxmas tree in the dashboard, idle is steady, engine sounds good.
Now here comes the thing, the temps of oil and water are at a proper level. When he steps on the gas pedal a few seconds later there is some sort of smoke coming out from the back of the engine (exhaust manifold, turbo, intercooler stock pipes from the SMIC) My question is cause he's not a mechanic and he will arrive tomorrow. crack manifold, shot turbo or some leak in the hoses?
aBtw the car has 105k miles.

Have a noise coming from their engine bay that kind of sounds like a bird chirping, but when you depress the clutch, it stops?

So my 1.8T GLI is making an odd sound that sounds like it's coming from the right side of the engine. Sounds like a busted bearing of some sort. Not too keen on this engine yet...

I just picked up a 20th about a month ago. It has 50k on it and recently I've noticed a faint whining coming from under the hood, most noticeable under idle and it changes pitch when I turn the wheel. I check the P/S fluid and it was low so I topped it off and I believe it has improved a bit but not too sure because I haven't gotten a chance to drive it yet. The steering does feel a little heavy but I figured that's normal because, well it's not a cadillac.

A 2003 20th GTI (1104). It has the 1.8T engine. Car has appx 75k miles on it, timing belt has not been done yet.
My concern is here: I checked it out the other day, and while it was running I heard a soft whirring sound coming from the engine. So I popped the hood and I couldn't really put my finger on what it could've been. I liked the car aside from that, and would like to get it, but I don't want a car with problems.

I've just recently starting getting a really annoying vibration coming from under the hood, only occurs while engine is running >~3000rpm's. Sounds like a metal plate shaking somewhere, any clues on where to check??

I had a friend check out a noise coming from my engine, and he said he thought it was an "idle pulley", and another friend say it sounds like my injectors. Its kind of a tinny sound and it gets louder as my RPM's go up. I dont know where to begin for diagnosis, but I heard it on a different Jetta about a week ago.

Mk7 GTI, currently at 5k miles but strong mildew smell coming from the vents.. I know the cabin air filters will last at least 15-20k miles.
I read before that the condensation hoses were sometimes installed incorrectly leading to run off inside the cabin. Can that be it?

My 337 didn't pass inspection (control arms, inner tie rod, no cat because the guy I bought it from sucked etc) but it sat for probably 3 weeks and I just sold my other car (I was planning on using that $2000 to get the 337 to pass inspection) but I just drove the VW down the street for the first time and it's making some scary sounds.
Basically when I give it throttle there's a high pitched whirring sound and something keeps rattling that sounds like its coming from the engine bay. I'm really freaked out, I'm leaving in two months because I'm transferring to a new college and I need this thing to run perfectly.
It's also shifting a little strangely and if you don't shift absolutely perfectly then it starts to rattle (not like you're about to stall but something completely different) I can't take it to a VW dealer or anything because I'm way over the 15 days past a failed inspection and I can't afford a tow.

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?

I have done some reading of past threads regarding both Gen 7 Camry with people having an issue with a strong smell coming from their vents after perhaps 1K miles or less on their vehicle. Looks like some people had it fixed (some fixing it by themselves) while others continued to experience the problem. Similar thread regarding Toyota Camry Hybrid but only brief thread. Then another thread regarding perhaps another smell like from plastics /battery (?) in Prius while I was on the Prius threads.
Has this problem been addressed/resolved either by Toyota or by owners who simply fixed it themselves? I also do not know if the Prius offensive odor (someone who was testing them noticed it while test driving) is a totally different thing (like I say someone said it was from plastics or battery itself, not sure.... )
These are things I never even thought of /considered when looking for a new vehicle, and never experienced in my older Camry.

The exhaust from my caprice if thick and white. And there's a strong carbon smell. Could this mean my cat converter is bad?

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.

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.

So i just got back into town after not driving her for about a week, started her up(barely), and saw engine light. While on the engine putters and sounds bad. The exhaust smells like gas. I have done no Mods except for APR stage one and a K & N air filter. Is it misfiring? Is my software bad?

Whenever I turn on the ac the air smells terrible and makes the ac almost unusable. I think there must be some mold or something.
