hey guys a recently took out my rs6 from the garage to drive it this weekend and everytime i drive it somewhere i have to jump it because it dies. today i went to a couple places and everytime i would start it it wont start. id have to jump it. the car does have electricity opening locking the car with the dash lights but doesnt start. the battery light, brake light, headlight all went on at the same time when i started it. also the window was very slow going back up. has this happened to anyone before?
