Insight to an issue that I had on an N54. TL;DR - while I had a code for an injector, 1, 2, 3 or DME internal fault”, It ended up just being injector number 2 internal fault.
My mosfets all tested fine ended up upgrading to msd81 from msd80 trash and all the injectors on the bank with 3 eBay injector and they leaked for while but still got the car around only slight misfire on start up
That’s the approach that I would take. If my injectors 4,5,6 were all throwing codes, either all of them are bad, or just one (even two) of them are going out and bringing the whole bank with them. That’s all of course, after testing my DME. Personally, I think testing the DME is easier than the test I explained in the video. You just need a good multimeter and patience.
god i hate my car. i have same issue but it happened while testing on a tune. i blew my 2 mosfets and had 4, 5 ,6 cylinders go down. replaced mosfets now 4, 5 wont activate. im guessing injectors now. it just has the 2e33 and 2e34 fuel injector activation code but no 30ba so could be short to i guess.
@@CarlosTorres-zx1yb replaced DME. non of the injectors had issues. if mosfets blow highly likely dme went with it especally if you tune a msd80 and have not upgraded to msd81.
I got lucky with it being just my injectors. Outside of this video, I did tests on my DME. At the time I did not find any issues with any of the MOSFETs. It’s 100% worth testing your DME. If your DME is fine, you’ll be back at the same square I was when I started this video.
Did you fix the problem cos i have the same problem too. My case the car doesn't start at all. And it doesn't specify which cylinder, it just say x,y,z I need help

I have this on my 335is on Cylinder 1 only getting
“2e30 dme fuel injector cylinder 1 activation”
Any ideas? Swap the injector?
Did you fixed it?
Having code 30bb 4,5,6 injector had dme tested and everything fine with dme am gonna replace bank 2 injectors and code them

What did you end up doing, same situation just cylinder 3

I sent my DME out to ECU pro with the same codes but they were still getting the codes on the car they plugged it into.
Sounds like the DME is the source of those issues. I’m not familiar with ECUPro but they should be flash you a new DME
I have the code 30BA and 30BB
