Ok this is a picture of a IVM on a F10,,,,the IVM supplies power to the DME for the injectors and ignition coils,,,now by chance you might have short circuit one of the ignition coils or power to a injector the IVM might be your problem.
will this is a little trick,,,you can cut the top off and you can see regular fuses inside,,,,just replace the blown fuse and you are ready to go again,,,instead of buying a whole new IVM.

One would wonder what they were thinking when they sealed that shut. Why did the fuse blow?

We have seen a fuse blown with a pinched harness,,,,BMW sealed it shut to make more money buying a new one,,,,instead of replacing a fuse

We found the pinched wiring harness near the DME,,,you have to start performing OHM test on each wire

Should I have power on pins 5 and 6 of that 6 pin connector on the IVM when the ignition is on? I am not seeing power there and so am about to try to cutoff the top to inspect. But because it is both pins it seems more that it might be a faulty relay, because I think they are driven off of the same relay. Your insight would be greatly appreciated.

I don’t know if pins 5 and 6 have power without looking at a wiring diagram

This is the link for wiring diagram, you may need to have an account with newtis, it appeaar that pin 4 has to be grounded by the DME before that relay energizes and provides power to pins 5 and 6, is that what you see here: https://www.newtis.info/tisv2/a/en/f10-528i-lim/wiring-functional-info/power-train/engine-electronics-mevd/voltage-supply/control-unit-power-supply/HTODAW62

Sorry I can’t see the wiring diagram,,,,but that is normal for bmw to have the ground wiring activate the relay from the DME
