2005 Volkswagen Polo burning oil

You need some punctuation in that huge sentence, otherwise it can be read at least three different way. I DO understand the oil is disappearing real fast. If you see blue smoke from the tail pipe, we know the cause. If not, there has to be a leak, and to lose oil that fast it should be a pretty big leak. If nothing is obvious your mechanic can add a small bottle of dark purple dye to the oil, then he will search later with a black light. The dye will show up as a bright yellow stain that can be followed back to the source of the leak.
