Question Help 2E33 Fuel injector activation

I am getting the code 2E33 fuel injector activation cylinder 4. A few weeks ago I got the 30BB code with cylinder 4,5,6 misfiring, I replaced all the mosfets and it ran well for a while. Now I got this 2E33 code for cylinder 4 so I replaced the injector same result 2E33 fuel injector activation cylinder 4. I opened up the DME to check the mosfets they're all good any ideas? This is on a 2007 335i.

Sounds like a harness problem. Maybe that's why the mosfet went bad in the first place.

Im guessing youre coding it. Also, is the index 5 a known working injector?
Perhaps swapping inj 4 with cyl 3 (since 3 and 4 are held together) would be a good idea to chk if code moves
