    Exhaust leak 2.0T

    I noticed the other day the car smelled like exhaust -- last night I used remote start and the smell was almost unbearable. I made it home, but I didn't feel good. This am, backed it out of garage, and couldn't even make it 2 miles to work. Parked it. Going to have to have dealership tow it in as it is too bad to drive 20 miles in it. Wondered if anyone else has had exhaust leak? I had the exhaust manifold/turbo bolt tightening recall done on it in the summer. I have 10K on it and it is a 2.0T.

    I am sorry to hear you have been experiencing an exhaust leak smell, WannaV. I would like to stay involved throughout your process while working with the dealer. Please contact me via private message so we can further discuss your situation.

    Took car to dealership and they couldn't duplicate the problem. They did tighten all bolts on exhaust system. Problem seems to occur only when I remote start car and let it idle for at least 5 min. I did notice this am that i rolled down the window at a stop and the exhaust was blowing back toward the front of the car and it had a very strong smell..... Is it possible that it is running rich without throwing any codes? I am running 93 octane and outside air temp is running 18-45 degrees F.

    Dealership has had my car exactly 1 week. Got a call today and they found the leak - said it was turbo wastegate leaking exhaust. Shield that covers turbo was coated with black soot. I am glad they finally found it - they really went the extra mile to find my elusive problem.
