325_driver 422 Report post Posted June 7, 2020 Pretty sure my e91 has a Parasitic draw on the battery, just had the battery go flat over night after a long drive from tauranga to Auckland. Will ista+ have any information on a module that was staying on causing it? I've tried doing voltage draw down tests on the fuse box, but the problem is intermittent so it's hard to test for it. Any common culprits for e9x? Quote Share this post Link to post Share on other sites

325_driver 422 Report post Posted June 7, 2020 No IBS I don't think. Ista said something about being ones equiped with nav or stop start. Anything in there to hint? Kms were 129,800 when it went flat, that centre console switch centre seems to be the closest possible one mileage wise. Or not really relevant? I have read in forums that those cig lighters can be a source of Parasitic drain, anyone had it happen? Quote Share this post Link to post Share on other sites
325_driver 422 Report post Posted June 8, 2020 Actually, wondering if anyone has had after market installations been the cause of this. (Bought it like this) The reverse camera looks wired in a funky way to the transmission instead of brake lights I would have thought, and sometimes it works, sometimes it doesn't turn off when I'm moving forward. Is this standard wiring round the O2 sensors? Looks a tad botchy. Quote Share this post Link to post Share on other sites
