as of a few months ago my z's battery wouldnt last over 2 days before completely draining - after getting a new battery the problem arose shortly about 2 weeks later, I would find the battery 100% drained the next day after use; not even enough juice to get the doors unlocked/locked with remote, a jump start brought it back to life each time

a mechanic had a look and he is 95% certain its the ipdm, would that be a common solution to this problem? didnt seem to find that being the solution to similar scenarios,

appreciate all feedback, thanks
