Well, i just drove my car to work and back, turned it off and then went inside to get my school stuff. Came back out and there was nothing. No lights, no click, nada. Came home after borrowing a car. lights came on when the door opened but when I tried to start, the car went nuts. there was a click...but it just kept on clicking and clicking...even after the key was out. I took out the battery and its charging now. The battery is brand new so im sure its not that. Alternater??? i was also thinking maybe it has bad connections to the battery??? not sure, any help would be amazing.

Thanks

Audi 5000/100/200 have a spliced main wire that goes form the battery to engine/electronics. This splice often corrodes. Since many of the parts are the same on the V8 it might be a good idea to check it out. Go to sjmautotechnik.com and follow the diagnostic link.
