I took it to a dealer and to an independent mechanic already but they dont want to put their hands on it without driving the car first to hear from where it comes from and guess what? every time they drive it the car doesnt make the noise! I had to make a video to see if i was crazy...
You can hear the noise at exactly 0:48 and it goes on from there.

I fell in a puddle whole the other night and 2 days later this noise started to come up. It starts only when i drive under 20mph but after a while it disappears completely and it comes back if i stop for a long period of time. I dont feel anything strange while driving other than the noise. When i press hard theres a loud bang noise. any suggestions?

 

It almost sounds like a heat shield against an exhaust pipe. Not saying that's what it is but that would be the first thing I would check. May have just knocked something loose or bent it going into that pot hole and it only makes that sound under certain circumstances. Just a thought.

 

nooo ^^^ i know what that is its the rubber around the top of ur windshield outside the wind is flapping it its a major fault in tc2 put a piece of tape over it so u cover it and noise should stop if it does u know whats wrong if not then sry
