You can use any intake cleaner and a lint-free rag. And your car amy not run good without adapting the Throttle body. I did align mine without Vag-Com by disconnecting my battery for a few minutes, connecting it, then turning my key to the ON postition without starting, and leaving it like that for 8-15 minutes, then take the key out and restart. It worked for my 99' 2.0, if it doesn't work the first time you may want to try again. Good luck!
