Some sort of leak?? Engine Bay

This is in conjunction to my earlier post about the engine shaking:

I just looked underneath my car and noticed that the whole bottom plastic cover underneath the engine is soaked in some sort of oil/gas/grease combination. It wasn't there before and I actually had the engine all cleaned by BMW as a part of their Spring Clinic. Now I also turned the fan on and I could smell gas in the cabin.

Possible fuel line leak or something causing the engine to shake due to not enough fuel going in?

What do you think?

I would start by removing the under shield and checking all your fuel lines and for oil leaks..
