White smoke that smells like burning plastic

Everyday as soon as I start my car white smoke appears on the left corner of the engine bay. I haven't really noticed a significant drop in my oil level. The smell of the smoke is similar to burning plastic. I also haven't really noticed an obvious oil leak. My antifreeze level is right where it need to be. I am trying to gather knowledge in regards to this problem to avoid taking it to an outrageously expensive BMW repair shop. Any help/suggestions will be much appreciated!
