when a car makes its way on the wet road it leaves back marks of wheel (marks represents patch).

which I sourced back to my car

This doesn't quite make sense the word 'new' seeming to not be required. However a straight translation is that the source of the wet patch on the road was caused by your car.

But! the statement would require further explanation such as "the source of the wet patch on the road was my car." Then the explanation such as "my car has a leaking radiator" or maybe "my air conditioner was dripping"
