The Bimmerprofs website documents this problem in detail, and also has some other really good information. Try putting the new injector into cyl 3.

I was caught out by this issue with an N43. It had a misfire on cylinder 4 which turned out to be a misfire on cyl 3. A lot of time/money was wasted before i discovered this. |
Wow that is very interesting...definitely could be the cause of my issue. I will replace Injector 4 and code it and see.
Meanwhile, I was reading where you had to reset the Adaptations on the DME AFTER you code the injectors. This was not included in any of the videos or DIY threads that I read. But, after doing so...the car runs perfectly fine now. Pretty smooth and no codes being thrown...
