Passat (B5) :: Exhaust Smell Through Heat Vents / Smoke Coming From Under The Hood
Feb 5, 2007
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?

I noticed a few months ago I wasn't getting much heat from my 99 Passat. I had the cooling system flushed and checked. Still no heat even after having all this done. Not long afterwords I started noticing that sweet smell through the vents, but couldn't find any leaks. I checked the expansion tank and it seemed to be slightly low so I added some coolant just to top it off and there it was. Steam started rolling up from the drivers side where the coolant had dripped on the exhaust and that's when I found the leak. I took the screws out that hold the tank to the bracket and discovered the leak coming from a short tube that appears to connect to nothing leaking coolant. Now here's my question, is the tank suppose to have a hole in it ? I thought it was suppose to be pressurized. What I don't figure is why didn't the shop notice it when they were refilling the system.

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 recently noticed that my car was starting to smell like oil burning off. Soon i realized that from time to time there would be a bit of smoke form under the hood I looked under the car and noticed that oil is dripping onto the cat but i am not sure from where. There is not alot of room in the back of these engines to see.

I have a 1985 Silverado where a mouse must have chewed through the main electrical wire that goes from the battery to the starter. Without knowing this, I tried to start the truck, it turned over a couple times, then a burnt electrical smell and smoke was coming from under the hood.
I replaced the wire and the starter. Now I have all electronics restored but when I turn the key, nothing happens. The lights don't dim and it doesn't even click. If I arc the solenoid on the starter, it turns over and runs just fine.
I have checked all the fuses and relays under the dash. Those don't appear burnt out and I've tried swapping relays and that doesn't work either.
Is there anything else that could have shorted out? Are there other fuses or relays that I'm missing? Or is there something with the ignition that could be causing it?

When I drive home from work at night I see a thin white smoke come from the right side on my hood. (Headlight area) I open the hood and I can't pin point it....smells vaguely on burnt rubber. I am new to a TDI so maybe I'm just being an idiot, but what is it? I drive spirited on the way home, but dont floor it. I do have one hill thats pretty steep I usually charge up...(fun to burn the rice rockets who struggle!) I thought maybe parking brake? Its only got 750 miles on it, so maybe its oil burning? 2006 v10

I purchased a Certified Pre-owned 2008 Lexus LS 460 in January 2011 with 29,000 miles. On April 2, 2011 I was parking my car and smelled wires burning and then saw smoke coming out of the hood. I immediately cut the engine, got my kids to safety and called 911. The firemen threw water on the engine and disconnected battery. It was towed to a local Lexus dealer and has been there since. They believe it was the starter, but the repairs as of yet are not complete. I submitted a claim with headquarters to give me my money back or a comparable vehicle. I am concerned about the safety of this vehicle and any residual chemicals and smoke that may remain with the vehicle.

I have a 2001 Lincoln Towncar (178,000 miles) with a heater core leak. I was on the highway and got some smoke out of the ac vents and ever since then I've smelled the sweet smell of coolant in the air coming from the AC. I haven't had any more smoke or vapor since the one time. I did my research and asked around and understand this to be the tell tale signs of a heater core leak and that it's one of those fun jobs that's going to be a high price tag at the shop because of the amount of labor (8-9 hours).
Since the dash has to come out, I thought it would be worth it to pay a little more and have a dealer do it since they'd be more accustomed to taking out and reinstalling that particular dash. So I describe the problem to the dealer over the phone and they want to diagnose it before giving me a quote on replacing the heater core. Why? No clue, I even asked the guy if there was any other possible way for coolant to get into the vents and he said not that he could think of.
Anyway, I took it into the dealer and low and behold they found a different coolant leak. It turns out for a while Ford used intake manifolds with a plastic part that is known to crack and leak coolant. The dealer wanted to replace the intake manifold and clear the condenser drain before we even got into for the heater core.
So here's where I get to my question. I ordered an intake manifold and replaced that myself, I still haven't addressed the heater core. The first puff of smoke and the coolant smell happened almost 5 months ago. I've been driving around with antifreeze in my trunk and my eye glued to the temp gauge and it has not budged at all. I started thinking if I could get through the winter months I'd just bypass the heater core and buy myself another 7-8 months where I don't need the heater and I could save up some cash to have a pro replace the heater core.
Now that the warmer weather is here, I'm left wondering--could the heater core really leak for 5 months without me ever having to add coolant and with the temp gauge never going above it's normal level?

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

The other morning I started my car up and no heat or air would come out of my vents. The night before I had to drive through a blizzard and my car was completely packed with snow. The climate controls function normally, everything is lighting up when i select a button, but no air is coming out of the vents (rear defrost and seat warmers work fine). There is no sound of the blower starting when I turn the air on, hot or cold. I live in Northeast Ohio so we currently have several inches of snow and it's well below freezing outside. I live in an apartment so my car is outside 24/7 between being here and at work. I looked up a bunch of posts on here and other websites to try to figure it out. I ended up taking my cabin filter out and it is completely packed with snow. So i vacuumed out the snow that was left in the cabin filter housing as far as i could reach. I also unpacked as much snow as possible from wheel wells seeing as the HVAC vent goes to there, and the blower still doesn't work.
What I am guessing, which I could be completely wrong, is that the HVAC vent is completely packed with snow and it's not letting the blower turn. I guess my question is does that seem remotely possible or is it something else completely? My climate control doesn't work on the highest setting so I don't think its the relay I read about and my heater has been working fine with no noises or anything and I don't believe it would just go bad out of the blue.

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.

Today I drove to dinner in my 2012 6.7 with no problems then on the way home my brother said he noticed my truck was white smoking quite a bit and he said there was a very strong exhaust smell coming from my truck ( he was in his car behind me) I ran a diagnostic test and what came up was code P0401 (I believe that's right). Need to figure out what is going on with my truck before I take it to the mechanics and get charged up. The truck still has DPFs in it just has a DPF back exhaust and has a AFE cold air intake running on a stock tune. However I do have the DPF deletes and EGR delete sitting in my garage just haven't gotten them on the truck yet.

So, at 14k it looks like I have that musty smell coming out of the AC vents. I've seen a TSB on here that addresses it. Hopefully my first trip to the dealership for anything other than an oil change doesn't present me with any other surprises.

When the car is warm with the A/C off(vent air only) you can smell an oily smell coming from the inside air vents. The smell is also evident from the engine compartment when exiting the car. I do not have any oil leaks that I can find and have been good about cleaning up spilled oil when changing the filter. I've had the car when new and it currently has about 63k miles on it now. The smell seems to be getting worse. No mods to the engine and everything else seems to be running well otherwise.

I recently purchased a 01 Passat 1.8T and noticed a strong 'used oil' smell coming in through the vents, especially at stoplights; the vehicle continued to smell badly when parked and turned off.
After looking around the PCV system, I found a small check valve near the airbox that was dry-rotted and non-functioning. As I continued to search, I found a large PCV hose directly under the intake manifold closer to the firewall. This appears to be ~3/4" hose that appears to be missing a connector. It appears as though there was supposed to be some sort of male/male insert and some clamps that are supposed to connect these tubes.
Any diagram or a DIY replacement walk-through for the PCV sytem on the 1.8T? Now that I've found the pcv break, I'd really like to get it changed out.

I've got this weird problem , it started a month ago. Sometimes I would drive for half a hour, park the car, stop then engine and some white smoke comes out of the hood after a few seconds. But sometimes I can drive the same amount of time, park, stop the engine but no white smoke.
The only time I did notice it happening is when my temperature gauge isn't working properly , sometimes it will give the right reading (which is right on the middle) and while driving it will drop to 0. Also sometimes there is a smell of rubber burning I think (Doing my best here). But I've checked Google for people with my problem but all I read is either people with tail pipes issues or smoke directly in the drivers cabin. My white smoke is only when I kill the engine. There is no smoke coming out of the tail pipe nor in my cabin. Only a rubber burn kind of smell.

When stopped at lights I start to smell burning oil coming from the vents when I have the heat on. It only happens every now and then and only when you are stopped at a light. I tried letting the engine idle after driving once and I can't smell it when i open the hood. I do synthetic oil changes every 5,000 since the car was new. I don't know what it could be? My last oil change was about 2,000 miles ago so I can't see it being burn off from the last change still.

Noticed a deodorized smell coming from dash vents when heater put on? After my 30k service I noticed the smell of deodorizer.

As the title states I have lots of blue smoke out the exhaust and the smell of burnt oil. Checking other posts it looks like it could be a diverter valve, a pcv valve or the Turbo. I checked on line and autozone and parts America say these are not required for my car. I checked my Hanes manual (yes, that's all I have) and they don't have the DV or the pcv listed.
