Question about 2000 Volkswagen Passat 4Motion

1 Answer

White smoke coming from AC and under hoods smells of burning oil

I've got a 2000 Passat Wagon. It's a V6.

Occasionally a white smoke either comes through the AC vents or from under the hood. I've never been able to stop and see where it is coming from under the hood, but it only comes out of the sides or close to the windshield. There is never a lot of smoke and after driving for a few minutes the smoke and/or smell goes away. It smells like burning rubber or oil. Sometimes you can smell it but not see the smoke.

My wife thinks that it may only happen when we are running the AC. It certainly doesn't happen every time we drive.

In addition, I have a check engine light and a message that says "Emissions Workshop." I've checked online and it seems like the message could be anything or it could mean nothing. If I unhook the battery, the message goes away for about a week, then returns.

    Mine is a 2000 VW Jetta GL. Not every time I run my AC, but randomly when I run it I see white smoke come out of the vents. I stop the car and turn off the AC and it stops. Nothing else happens. The air stays cold. Everything else seems normal. Still can't figure out why. I've called many auto shops and all have said they need to see it happen in order to diagnose, but it does not happen on command, so still a mystery.

most autoparts stores will run the check engine light for you for free....I am assuming that you either have a clogged catalytic converter, or your o2 sensor is throwing a fault....have autozone check it out and post back.

White smoke is coming out of my vents


White smoke is usually indicative of a blown head gasket. Usually if you have blue smoke it's oil......If you have white smoke and possibly a "sweet" smell to it, that's normally coolant.
If it's coming out of your vents then I'd say you need new gaskets now. What's happened is the gasket blew out so bad that the smoke made it's way through the vent system, it's also coming from under your hood I bet giving my past experience with this.
Definitely new head gaskets to fix this though.

2012 kia sedona white smoke comes out of exhast when first started


White smoke is usually an indication of burning antifreeze and burning oil would have a more bluish tint to it and smell like burning oil. If it's a 2012, isn't it still covered by the KIA warranty though??

White smoke and the smell of burning rubber. I have had lots maintenance of work done to my car. I was starting to notice and smell burn oil. I had a small valve cover leak so I just had the whole...


Bradley,
You have stated two problems. Coming to second first. Smell of burning rubber. in the car rubber is only at two places where it can burn, The tyres, unlikely as you have not commented upon your driving habits. Some people like to rev the engine so much before take off that the tyres go burning for the first few hundred meters. And then there is rubber on the wires and cables. You have to check the wires for any heat while the engine is running.
Coming to the first now. White smoke is generally of unburnt fiel and not oil. Oil alwayd give black smoke and that is the indication you get when the exhaust is giving black smoke. That means that the engine is consuming oil. if it is white then that indicates that the engine is cold and burning more gas/diesel. Is your a diesel vehicle?? But as you say it from under the hood. And that too behind the engine block. May be that the gasket is leaking from somewhere. If you could check the engine oil level for a few days early in the morning before starting the engine. If the level drops and the exhaust tail pipe does not blacken your finger when you rub it in it would mean that the oil is being burnt. Now what I suggest is that with the engine running and hand brakes on, go under the car with hood open and try to locate the source of the smoke. I am sure you would be able to locate it.
Then we talk again.

Smoke is coming out from under my hood...checked antifreeze and oil so it fine


white smoke usualy tells about a leakage in the cooling. check that. dont forgett to refill. get it repaired or DIY. attention: could be really hot.

if it smells like fuel, a fuel line is broken. then dont drive any more since it can catch fire.

if the smoke is not white, go to the repair shop instantly.
