Audi A4

Audi a4 quattro 1.8t

I do not drive my car much but the past weekend I drove it a few hours to NJ. (Which ive done several times). Got an oil change and tire rotation there 2 days before I left to come back home. 3 days after I came home (and not driving it) I was going to drive it and it wouldnt start! It took about 10 seconds to catch! Very very weird. Then I went to put the windows down and they werent the same (i had to hold down the button for as far as I wanted the windows down, unlike usually where you push it once and it rolls all the way down). I thought I heard a slight noise from the engine area, but im not sure.
still cant start it normally. What happened?
