Alternator went out the other day, now I know that there were two main different types installed in this era Audi and they are not interchangeable due to the adapters appearently. But I cannot find a replacement alternator for the one I have currently anywhere... It's part number is 078903016 F. It's a 14v 120a. Can someone please help me find one and or one compatible. Preferably not something cross country. I'm out of Seattle and would love to have it in the next day or two
Any help is appreciated
