ookii 2 Report post Posted July 14, 2023 Is It true that there's no fuse in BMW e92 series there's you could tap for 12v constant because the system turns it off after 30 minutes? If yes, what's the other option without draining my battery? I've read you can tap directly on the battery, but you have to tap it with a fuse which I don't know what fuse I should be using. Thanks!

Eagle 1661 Report post Posted July 14, 2023 Its the modules which go to sleep not actual 12V feed. All you need is to do is find a 5A rated fuse which has constant 12V being supplied to with the key out (use test light or multimeter). Then you just install in a mini fuse tap adaptor to piggy back off that and run your wiring. Quote Share this post Link to post Share on other sites
