jetta will start but wont drive HELP!
 

Well, I was driving like usual and all of a sudden something in the engine broke or something because there was this loud scraping noise and immediately the car wouldn't drive. So I just nuetraled it into a parking lot, all the while, making noise. I stopped and tried to restart it, it started up but wouldnt go anywhere, like if I was trying to drive in nuetral. The EPC light is on, maybe the check engine, I dont remember. Can someone tell me what kind of problem this could be and a price range to fix it. If its an easy fix, maybe I can do it but I doubt it. Just wanted to know, thanks in advance
