1999 Audi A6

Engine Performance problem
1999 Audi A6 6 cyl All Wheel Drive Automatic 170000 miles

a couple of days ago, my car was working just fine. I went to work and forgot my lights on, when I came back I had to get a boost to start it up. I got back home and charged my battery, but now my car seems to not want to shift and its real sluggish. My car wont accelerate at all. And when I go up hill I can barely go 40 km/h. Can you please help me with my problem?
