If I rolled down the windows and ran the car hard, I'd smell something bad. It's hard to describe the smell but it seemed to me that something's burning.

 

hopefully your clutch

 

Got any exhaust leaks?

 

I know my clutch is wearing down (needs to be replaced), but I'm not sure about the exhaust leak. How do I know if there's exhaust leak?

 

Smelled like burning oil?

How many miles do you have on your car?

If its oil, it is either:
-rear main seal leaking onto exhaust
-secondary turbo leaking onto exhaust

 

Maybe it's the oil, not sure. 141k miles on my car. Oh yeah, I'd only smell it after second turbo kicks in.

 

Check under your car; look at the secondary turbo and see if there is oil droplets at the bottom of the housing, and also see if there is oil burnt onto the main catalytic converter and back.

How much oil do you see on the ground after driving?

 

My mechanic just did the oil seal for the turbos, so there should be no leaks.

 

Is it a rotten egg smell??? I would check to see if you main cat is glowing try looking at night.

 

How about your brakes??
My .02 cents.
