Question about 2004 Audi A6

1 Answer

04 audi a6 2.7t i noticed a chemical/plastic burn smell when i would run the car for a normal drive from a to b but today i lifted the hood and saw white smoke coming from underneath the coolant tank.

It was underneath the coolant tank, not directly, and by the heat shield an manifold. hard to see or get there i can't find out whats happening. it's like something is maybe leaking onto the engine block and burning but i don't know why.

The coolant overflow tank may have started leaking.

    that's what i'm starting to think because i see where the smoke is coming from off the exhaust manifold and it really doesn't look like burnt oil drippings to me, hopefully it's just the overflow tank and not something worse

Smoking from under hood


A leak of some fluid, probably oil, dripping onto the exhaust. This smells terrible, and it only needs a drop or two.

Burning plastic smell from under hood


You will need to check where the liquid is coming from, It may be anything from Air Con, Fuel, Transmission Fluid etc..

The fact you smell burning plastic could be 3 things..

1, Brake pads could smell and burn down if they are on too tight (Had this problem with a trailer). Hence when you apply the brakes it could be squirting brake fluid out due to too much pressure.
- Check brake fluid

2, If the smell and liquid is inside the car (front pass side) it could be the air ducts. Under the dashboard you have air ducts etc for the fans and in car cooling (brother had issue with this)

3, Whatever the fluid is, it could possibly drip onto something hot, unusual for liquid to smell like plastic though, Auto transmission oil smells like fish.

Best bet would be the brakes. Next time you smell it just smell in the wheel mag and see if you can smell it, check the engine fluids often and dont use A/C (Air Con) as that does drip fluid (normal). If it is the brakes smelling you will need to have the lines bled out, tyre places may be able to do this, and possibly new brake pads

Good luck

I recently had a 100,000 major service on my 2004 TL. Within a couple days I noticed a pronounced smell of burning oil. I have since noticed a puddle of oil has formed under the car and just today there...


It's probably OK to drive. I imagine they failed to get the oil filter properly seated and you're getting a little leak there. DO BE SURE to check the oil level before you drive it and add if necessary.

Ignition switch was sticking for weeks but starting i would start the car then pull the swirch back a little an everything was ok i had a music system installed one day five hours later my head lights...


It sounds like you have more than one problem with your Audi. The coolant leak and the ignition switch are two separate issues. I would recommend that you take the car to the Audi dealer or to an independent garage that specializes on German cars and have the vehicle checked.

2005 Chevy Impala exhaust smell


neither one of these would cause gas to leak. sure it is not coolant ? if you think it is gas it is not safe to drive car as it could catch on fire. possible cause would be a leaking injector.

2000 Audi s4 has strong smell of gasoline


Pop the hood and check all the fueling lines, then check your gas tank and see if you just spilled some. Then check your exhaust pipes because you are probably running rich. You may need to change your spark plugs, or possibly a mass air flow sensor, or oxygen sensors. you should get either a vagcom to scan it or an OBD-II scanner.
