Gas cap and oil/headlight caution light
 

i have a b6 1.8 and a while back after i would turn the car off it would beep repeatedly and then for a long time like the lights were on. The caution light for oil, the gas cap being off, and some headlight washer one keeps flashing. Sometimes it does it and sometimes it doesnt but i took it in to our place where we take all of our dubs and audis and they said they fixed it but later that night it did it again. Has anyone had this problem?
Any solutions?


P.S. where can i get an oettinger grille for cheap to go with my oet bumper
