Re: 2003 A6 3.0, white smoke from engine bay (plastic smell) :S
I never said it was from changing my oil. I just didnt think it was oil burning because of the plastic smell.
But I found out synthetic smells like plastic when burnt.
It happens when the engine is hot. Right now I am assuming valve cover gaskets.
I will have the shop look at it next time its in. No I dont have any after market subs or amps. My headlights are stock.
Thanks for responding I will post what I find out. Right now I am still driving it and it doesn't always happen.
That day it was warm out.

Burning smell for changed oil, I don't think so. Either oil is dripping on to a manifold or exhaust or that a wire or something is either in contact with something hot or electrical.
Can you smell it right at start up, when the engine is cold, or you have to wait awhile till it gets warm?
You don't have any aftermarket subs or amps? or mods (such as aftermarket HID?)

Re: 2003 A6 3.0, white smoke from engine bay (plastic smell) :S
im having the same problem now..dosent over heat or anything and runs great just when I stop the and pop the hood it has slight smoke from the left side only with similar smell....thanks in advance.
I have a 2003 A6 3.0 with 100k, there is white smoke coming from the left back side of the engine bay (plastic smell)
. It has happened at least three time now but only when the outdoor temp has been +32*C (from what I've noted). The temperature gauges all read normal and there's no check engine light on, scan is all good.
I was at a red light once and it billowed out the passenger side wheel arch with an overwhelming plastic smell, then just stoped
Does anyone know what the cause of this is?
Thanks in advance!!

Did you ever figure it out ? I have a 04 A6 C5 3.0 and same thing is happening.
Bought the car in the winter all was fine. Now its starting to get nice out and I noticed smoke from passenger side.
I popped the hood and the smoke smells like burning plastic .
Not burning oil , Not burning rubber but burning plastic.
Its coming from the passenger side close to the fire wall.
Anyone ?
Thanks for your time.

Did you ever get a final resolutation to your smoking problem ? I have a similar problem. I have white smoke on the left side of my engine compartment when the car is first started (from cold). The smoke smells like plastic burning, but it goes away in about 3-4 minutes. I'm really wondering what this could be.

Forgot all about this forum lol.
The dealer told me it was probably just some coolant that had leaked out of the reservoir and it wasn't a big deal/ was common. It mostly happened after the car was warmed up and the outside temp was 35degrees plus (rarely). The car never overheated it just had some white plastic smelling smoke that came out once in a while. I don't own the car anymore so I don't know if its still reoccurring to this day.

thanks for the reply I appreciate it...I guess I bought a "lemon" I drove 8 hours out of my way drove the car on the interstate and the thing over heated...dropped it off at the nearest shop and had some hoses replaced and the timing belt plus the water pump and thermostat so I was praying the smoke was nothing too expensive or a DIY project....great care but built cheaply... thanks again!
