Golf IV / Jetta IV :: 1.8t - Oil Smell Inside Car And From Exhaust
I'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?

2000 Golf Gl AEG 2.0
My car smells of fuel in the exhaust and when checking the oil it is mixed. I have a cel and it says the o2 sensor is bad, not sure if a bad o2 would be causing all of this or not. The air filter is clean and I have done a few oil changes also. The oil is low also after so many miles but cannot seem to see any leaks.
Car also has over 200,000 miles. Is it necessary to change the gear oil in the vehicle?
Golf IV / Jetta IV :: Bad Gas Mileage And Exterior Gas Smell

for your information, i have already changed the pollen filter withe a new one.
Golf IV / Jetta IV :: CEL On / Misfire And Smell Of Gasoline
I just recently picked up a 2000 Jetta VR6. its 173k miles on it and has few issues with it.
The Background. The car had a check engine light on and when i bought it I was told it was just an o2 sensor and i trusted him cuz i knew the guy (sorta). Bad move on my part, but not terrible. After I bought the car, i took it to autozone to just get the codes and be sure. It came up with a P1116 - o2 sensor heater circuit open on bank 1 (expected), and I also got a P0302 - misfire cylinder 2 (dafuq?). The misfire surprised me cuz it did not feel like it was misfiring whatsoever and it did not have flashing CEL.
After driving the car for a few days, I have noticed a few things that make me believe that it is either a faulty injector or seal.
1. The misfire, but not significant misfire. The only time I can tell any difference on how the car performs is when its at idle, it tends to not idle completely steady and vibrates a little more than what an engine should. Other than that, the car pulls great and not any issues.
2. The smell of gasoline is prevalent. It takes about 30 seconds before it just plain out reeks. And if you pop the hood and stick your nose right next to cylinder 2, you probably get high off the fumes (if that's possible). I am sure its coming from somewhere under the plenum because it was leaking some type of liquid that I had initially thought was just oil but I really think its gasoline.
Golf IV / Jetta IV :: 2004 - Strong Gas Smell When Idling
I have a 2004 Jetta w/ the 2.0 engine, auto transmission. Lately it has developed a very gassy smell when idling. Could be all the time I guess, but I only ever notice it when idling. It seems more noticeable on the passenger side of the car, or maybe my wife just has a better sense of smell than I do since she noticed it before I did.
The car seems to run fine, about the same as it always has. The idle is slightly rough, but it has been like that ever since I got the car. I got it with about 110,000 miles on it and had the timing belt and water pump replaced as soon as I got it. Mileage now is about 130,000. No info on the maintenance history of the car, but when I had the timing belt changed they said it looked like it was probably the original one.
The check engine light has never come on. I think I'm due for some new spark plugs so I was going to be replacing them soon anyways. Not sure what to check out here that might be causing this?
Golf IV / Jetta IV :: When Run Defrost With Heat On / Antifreeze Smell
I have a 1999.5 Jetta 2.0 question:
When I run my defrost with the heat on, I smell antifreeze pretty strongly. I am also having trouble keeping the windshield defogger/defrosted without the heat constantly blowing on it. Signs point to heater core, right? So I tried a bottle of Bars Leaks aluminum radiator stop leak with the metal flakes in it. When I run the heat on the feet or front/face/torso setting, it does not smell like antifreeze (unless it's when it very first starts and it's so slight that I don't notice). When I run the defrost with the heat on, it smells pretty strongly of antifreeze. I see no antifreeze on the passenger side carpet.
Golf IV / Jetta IV :: 1.8t Sounds Like A Diesel / Gas Smell In Engine Bay
My 2005 gti 1.8t started sounding weird a few days ago, it has a really deeper tone to it, sounds like a truck or a diesel. I can also smell gas in the engine bay, car seems like it runs fine just sounds really funky. Sound gets louder as I accelerate.
Here what it t sounds like right now. Sound is coming from top of the motor or behind it near downpipe, not beneath the car from exhaust.

Golf IV / Jetta IV :: Cranking But Will Not Fire - Fuel Smell
2000 1.8t 5 speed Jetta ... The car has run fine up until recently when I started having some starting issues. It was intermittent, and got more frequent and longer. The car will crank but not fire. In the beginning, I could crank it for a few seconds, turn off and turn back on and then it would fire like nothing happen. This continued to happen and progressively get worse until I could not get it started, I could smell fuel which lead me to assume I had to spark.
Today I went out to swap crank sensors but only tried for a little while and cant really get my hand up there. So, I disconnected the battery for a while, went back and connected it, and it started. Up until this point I have had the same 2 codes, over/under boost, but the car has always ran with them present. I scanned today and got a p1545 Throttle position sensor code...But only got that one time. Ive been messing around with disconnecting and reconnecting the battery and among one of these times, the EPC light came on and would not rev passed 1k rpm. turned it off, turned it on, and it was fine after that.
Im sure I have a sensor about to let go Im just not too sure which one it is. I dont have vcds and am not getting a low signal code from the crank sensor with the scanner I have.
Golf IV / Jetta IV :: Won't Start - No Smell Of Gas If Pump The Throttle
I have a 2.0 IV 5sd
Today it won't start, and there is not any smell of gas if I pump the throttle. How long to fuel pumps last?
Should I just replace it? I have to admit, nothing has gone wrong with this car since it was new!!!!!
Golf IV / Jetta IV :: Burning Oil Smell From Engine Bay After Driving For A While
My engine bay smells of burning oil after driving for a while. I have cleaned up the engine in order to find the leak. There is some gunky residue on the belt side of the engine but that wouldn't cause the smell.
Crawling under the car I found that there appears to be a leak between the (what I think is) the aluminum intake side of the turbo and the cast iron center. You can see it in the videos below:

This is the only leak near the exhaust that I can find. Does this mean that the seals inside my turbo are toast and I will need to either rebuild or replace it? What is the best course of action? Rebuild? New OEM Turbo?
Golf IV / Jetta IV :: Coolant Burning Smell - Car Overheating While Driving
Last night while i was driving my car began to overheat. I could smell coolant burning. I pulled over and opened my hood. The coolant inside the coolant pod was boiling. Some coolant lines were steaming as well. I could also hear a gurgly like noise coming the engine. This is a 1.8t gti

I am looking at a 05 GLI 5 speed with 133k miles. I drove it yesterday and it runs fine, but I smelled coolant after I turned it off. I was told by the dealer that the turbo is leaking some, it was spooling while driving and didn't seem to do anything funny. The check engine light came on and said coolant was low when we got back, when I cranked it back up the light was out. Just not sure about it.
View 4 RepliesGolf IV / Jetta IV :: Hot Rubber Smell When Under Periods Of Extended Boost
I have noticed that my car makes a hot rubber smell when under periods of extended boost. I live in CO and there are sections of road where, just to maintain highway speeds, my car will hit and hold 5psi as I motor up a mtn pass or very long/big hill...that could be a few miles with periods where it might just drop to 0 for a minute or two depending on traffic or a spot where things level out for a sec. (Downshifting doesn't really change this, only the rpm range...the hill/load stays constant)
Anyways, I don't notice this any other time. No visible oil leaks. The catch can is emptied. No smoke from engine or tailpipe. So I am fairly certain this is rubber I am smelling.
I am wondering if perhaps it's just the turbo getting hot enough to make the stock boost hose smell? It seems obvious to me that it is directly related to turbo heat. All searches I have done lead me to crayon smells or burnt oil...this is neither. Car runs fantastic otherwise, but this smell just sucks.
Golf IV / Jetta IV :: 2001 - Hot Plastic Or Wire Smell From Vents
I have an 01 GTI GLX with climatronic, and I've noticed this hot plastic or hot wire smell in the vents. Yes the fan wire gets hot when the car is hot and AC is on. But I don't think that's it. I've torn the passenger side apart, took the blower motor out, not it. The vent / recirculate motor is external to the vents, the only other place is behind the radio for the other one. What else is internal, if anything, that could be causing this smell? I'm concerned that something will melt or burn up.
I've been wondering if the ecm in the cowl would be getting hot but I can't smell anything with the plastics on. I would say it does seem to occur after driving for about ten minutes in town. But it also seems like it's there when I first start it up also.

Golf IV / Jetta IV :: Smell Of Antifreeze Coming From Vents - Heater Core?
My car had the smell of antifreeze coming from the vents, but it goes away when I use the "recirculating" button. Do u think it's the heater core? I hope not though. Also how much is the coolant suppose to be filled up too? Mine filled up a lot more then half the reservoir.
