Hey, im new to the site and a this is my first audi. Im having some weird problems with the car. I went out to my car and the battery was dead so I jumped it and it wouldnt turn over. All the lights turned on and I could hear it trying start for a second or two then it would stop and start making a fast ticking sound sound. I left the car over night and made sure all the lights and electronics we're off. Next day battery was dead again, I jumped it, charged it for awhile and it still wouldnt start. The battery died again after I left the car for awhile. The dash is showing an epc code. I searched that and came up with a possible crank position or a couple other possibilities but i cant seem to figure out what would be draining the battery. Any help is extremely appreciated. Thanks
