Yoda, if it were me, I would ask them at the Audi forum. Sometimes people can find really helpful folks on forums. You may want to make sure to tell them that you are strapped for money and know almost nothing about cars. While you know nothing about fuel injection, you are pretty good at giving injections . I bet if you keep asking and letting them know your situation, someone will take an interest in helping. Often thats why they are there. They want to help. Just a thought.

I got great help from people on "AOL helping hands" forum. Someone actually helped me on the phone to download and reinstall all programs and software after I unexpectedly reformatted my computer. Its what she enjoyed doing. So she hung out there to help. And she was not the only one. So, maybe you can try turning more to the folks on the Audi forum to get things squared away with the car, if it feels right to do that?
