I hope you guys can help:


I recently bought an Audi A4 and have been having problem with a draw on my battery that only happens once in awhile (every couple weeks.) Since it is so inconsistant, it is hard to test for since nothing ever seems to pull on it while they are physically there testing it.  The frustrating part is sometimes it will happen, I will jump it, and it will start without a problem for another couple weeks and then BAM! one morning it will just be dead.
The switch and starter went out recently and we hoped that was the cause. After replacing those it went another couple weeks and the draw came back. I am worried whatever it is will cause the switch or starter to fail again.  

I love this car, but I will have to get rid of it if I can't get it to consistantly start! Any advice would be great. I have already spent way too much having mechanics try and fix it.
