Hey Everyone. I have a really strange question... I had a couple of large plants in my car for a couple of days. Now my car smells like a green house every time I turn it on. It goes away after a few mins. of airconditioning. I have a C230 Sport. Can anyone tell me where my air filter is and if I can change it myself. Also, do you think that that is the problem? Any help would be greatly appriciated. Thanks!
