I think I'm in the same place as you. My car has absolutely no power and there are some metal clanking noise. Happened fairly quickly. Although the noise seems to toggle somewhat with my AC. If the AC is off the noise is worse. Does that make sense. Also, I was curious if I was to get a K04 turbo would the total audi performance chip work with it or would I need to get a different program? Any help is appreciated. Thanks!
