well let me start off by saying im new to foreign cars. my last 2 cars have been mustangs and the mpg's on those things are shitty so i decided for my 3rd car i wanted something more economical and landed upon a 2001 audi a4 2.8l with 71k miles on it. real nice car...but already notice a few problems...i have an oil leak and im worried about the parts/labor in getting it fixed. and also the passenger windows dont seem to work but the drivers side do? the drivers and passengers side power seats dont work. only the top part of it but not the up/down and forward/back ***. and the light that says one of your lightbulbs is not working properly turns on when you turn the lights on. i checked all the bulbs and they seem to be ok? well theres a little intro of my car and the problems it has...any help will be welcomed and greatly appreciated..

thanks
