Sorry if this is the wrong forum but I'm trying to help a friend with his 09 cabriolet. We just replaced the battery and alternator and after 5 days of him starting the car, it's now dead again. I'm at a loss as to what could be the culprit. Any ideas are welcome. Thanks guys.

I had the same problem once, I believe it's was the light auto switch, turn it to manual and the trunk light switch didn't turn off when closed, removed the bulb to test. it never happened again.
