1998 Audi A4 filter element problems.
 

My 1998 Audi A4 2.8l has a problem. The filter element keeps running when I turn the car off. It is also drawing power off the battery of course and ran down a brand new battery. The car has been parked for about a month now because of finances I'm scared to see how much it will be to fix it. When I tried to jumpstart the car as soon as I hook up the cables it starts running again and I can't even jumpstart it. I'm not sure what to do. I'm gonna take it to a shop for sure but I wanted to know if anyone else had this problem or if anyone could tell me what was wrong and how much it might be to fix. Thanks in advance. If you have any questions please ask I'll be here for a while. Thanks.
