99 passat 1.8T... Just started yesterday, may be due to the cold weather now, but it has a strong fuel smell upon cold start... Under the hood, the smell seems to be coming from near the air box... Anything there that could be leaking?

Fuel line after the fuel filter going to the engine has sprung a leak...
Either way fuel line part number 561-130-307 is leaking wanted to give another heads up to people who are experiencing diesel smell inside the cabin...
B5 1.8T - A few weeks ago, I had some battery issues. Long story short, I ended up changing the battery. A few days later I began to have an issue with my coil/ICM. I decided it was probably a good time to do the delete and conversion to 2.0FSI coils. Before doing that, I used a generic hand held scanner to clear codes and see which would come back just to have a baseline for after the conversion.
At this point, car is not starting at all and I'm getting smell of fuel after cranking. I pull out plugs and see they are soaked with gas. I probably shouldn't have, but at this point I went and converted everything over, expecting that when I was done it would start....
Meanwhile, at this point the car cranks but doesn't start, and it seems as if fuel is dumping into the cylinders. Hooking up to an Elmscan5 and Scantool software, I get absolutely no codes (it IS connecting to ECU to some extent). Im not even able to get the cable to work at all with VCDS lite..
So I have NO codes and a car that turns over but wont start and smells strongly of fuel when I'm cranking it.. I am reluctant to buy anymore tools or software at this point; I'm thinking maybe I fried the ECM, or could it be as simple as throttle body adaptation?
Ok, 04 Passat, 1.8T AWM
CEL is on for po456 (very small evap leak) and every time I fill up on fuel, I can smell a STRONG fuel odor, from near the fuel neck, and inside the car. Stops after it hits around 3/4 area. No leaks, and the car runs fine. Gas cap, and N80 valve were just replaced, both parts are from the dealer. I'm going to bring it in for a smoke test soon. All recall notices have been done too, I just did the timing belt.
I was one of the many lucky ones to have my engine stall on me, and just had the replacement put in back in April. Drove the car from San Diego to Phoenix, and everything was fine.
A couple of weeks ago, I noticed some gas vapor fumes coming into the car usually during the initial start up, and then the smell would go away.
I read some old threads from 2011 about the pcv hose causing this issue for many owners, so I replaced both the valve and the hose. This hasn't solved the issue, and when i run the vehicle and inspect under the hood, the fume smell is still coming from that vicinity.
Is there some other valve nearby that i should inspect or replace?

I was checking oil and noticed fuel smell in oil. lot of short trips but also driven til hot at least a couple of times every week with long rides weekly or bi weekly.
Also smelling gas on start up and first minute or so. Some fuel smell in exhaust. The jeep runs well.
Today I was out test driving trucks. I found a truck that I fell in love with down the street from my mom's. It is a Ford f150 with a 5.3L Titan V8 engine with 4 wheel drive. When I went to test drive it with the initial turn of the key it smelled of gas but quickly went away. When I went down and had the step dad take a look at it we smelled it again but it went away even quicker the second time.
It has been sitting for 6mo prior to this drive other than it moving from Point A to Point be about 3 months ago.
Might I also add.. I bought the truck. My brother in law asked me if it was fuel injected and had that smell, I said "yes". He said I would have a big problem. Do I?
I'm checking all places to look for a fuel leak. I park on a concrete slab, with no drips.
I have already mopped up as much fluid from the valley from recently having all of the injectors replaced. I still need to clean it further with simple green, and stuff white paper towel in the valley so I can really know if there is a leak.
3 years ago I replaced the water drain valve o rings, but I suppose they could have gone bad again.
I have been getting a smell of Diesel Fuel into the cab of my truck, its not an exhaust smell but an unburned fuel smell...
View 6 RepliesWhen I turn the key all the way over, I hear only one click, and no engine sound. Playing with park or neutral positions do nothing. Battery and connections are good. I am getting a raw fuel smell out of the tail pipe after it finally starts. The check engine light intermittently comes on, by now it is mostly on.
My guesses are: fuel pump/relay problems, starter/connection problems.
I own a 99 Mk4 Golf 2.0L the issue I have been experiencing for almost a year now. Is that I'm getting a fuel odor smell every time the car is either idling or moving. My check engine light is on I have also noticed after pumping fuel the car has a difficult time turning on. It eventually turns on and runs .
View 6 RepliesI have a 2003 F 350 Diesel. When the heater is on, I can smell diesel fuel through the vent. This happens mainly when I am at a stop sign and the fan is on high. I did some research on this forum and found some others with a similar problem. The question I have is it seems like some said it was the cracked injector cups or a leak at the reservoir on top of the motor where the filter is. What I wasn't sure of was the symptoms. If it is a crack injector cup, would the smell be all the time and not just when I am stopped at a stop sign? Or would it be intermittent as well? It is definitely not exhaust smell. It smells like fuel. If it is the gaskets in the reservoir, I think I will do the blue spring replacement cause that seemed to improve a couple things based on the treads of the forum. I do see drips on the pavement every once in a while at the front of the truck towards the passenger side of the truck. Not all the way to the side near the tire, but off center on the passenger side. Is there anything that could be leaking fuel on that side of the motor?
View 4 RepliesI have been smelling fuel on and off for the last few weeks. I thought it was the fuel bowl drain valve so I ordered the kit for the whole fuel bowl from diesel o-rings. I did the rebuild this morning and I don't see any visual leaks. Still smell a strong odor of diesel though. The lower engine cradle is all wet and the valley is still a little wet too. Could I still have a leak and if so where to look? Could it be just wet still from draining the fuel bowl and needs time to go away?
View 14 RepliesI've thought I smelt diesel fuel on an off for a while, but never found the source.
Tonight, 17 degrees out I have fuel in the valley and it appears as if the back of the drain valve is wet.
A fuel bowl rebuild is on the short list. Is this typical, the cold weather brings the issue to light?
New to me 2003 F250 Super Cab 6.8 V10. Great condition inside and out. 68,000 miles. Began smelling fuel (gas) a few days after driving it 250 miles from purchase location. Traced leak down to the top of the gas tank. Staining was visible around the rear vent. Applied about 5 psi to the tank and sprayed soap around until I saw bubbles coming from a hairline crack at the rear vent connection. Its where the fitting for the hose comes out of the tank.
My first choice would be to hot weld the crack. I'm not very comfortable with the idea of a heat source near a gas tank. I'm not sure, but the heat from the plastic welder might be hot enough to ignite fumes? Second option is to try some industrial 2 part epoxy (PIG) and seal it with that. Is there pressure inside the tank, and if so how much? Can try this fix with epoxy or JB Weld?
Alright, my dad taken it to a mechanic, and guess what, it's still there. Only happens when the engine's warmed up. This is pretty much all I know, but it comes in through the a.c. and seems to come out of the engine compartment on the passengers side.
View 6 RepliesI 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.
View 1 RepliesWhenever my Passat is at idle I smell gas and it gets stronger the longer I'm stationary.Would this be part of that gas tank recall earlier this year or something else? VW didn't send me a recall notice on this.

After almost 9 years, 130K miles on my 2000 GLX wagon 5-sp., for the last 6 months I'm noticing an increasing oily "smell" when at idle after the engine is warm. Other posts suggest it might be a leak in rear cam seals or valve cover gasket dripping small amounts of oil down on the exhaust system. There's been no visible oil leak when the car is parked and it does NOT "use" oil between every 5K changes. Is replacing the valve cover gaskets a job within the reach of a moderately experienced DIYer?
View 3 RepliesSomething really strange is happening as I opened the hood after stopping the car the other day and it seems like something is burning ( doesn't smell like oil ) and smoky is coming out from the left side of engine compartment?!? What can it be as I can't see any oil leaks or anything? can something be melting
View 1 RepliesHaving burning oil smell coming from the V6. Took it to the dealership and they tole me it has an oil leak on the the header then it burns off. It seems to get much worse when the RPM's are some what high. Only 70,000 miles too. Guess its getting to stay that way for a while.
