N63TU Injector replacement
Well, looks like at 125k miles my 2016 X5 50i needs new injectors. I’m getting “bank 2 lean” when I give it a healthy amount of throttle.
For those of you who have replaced your injectors, any special tips or tricks? Anything I should look out for? Special tools needed? Possibly an “injector puller” I’ve seen? I know the injector compensation numbers will have to be put in the ECM. . |

You sure it’s the injector and not the HPFP?

Is there a way to test the fuel pump before replacing it?
I did get a “bank 2 lean wide variation” code in addition to just bank 2 lean…would that indicate fuel pump instead? |

Agreed…checked using smoke and didn’t find anything. I figure at 125k miles it’d be good to refresh the fuel system, although it sucks to be spending even MORE money right after Christmas lol

if you’re able to datalog or watch rail pressure under WOT and it crashes, that would tell you it’s the high pressure fuel pump.

On BimmerLink I was able to find “filtered rail pressure” but it isn’t separated into bank 1 and bank 2. Any suggestions as to what to search for? |

I’d have to search myself on BimmerLink tbh. I know on BM3 and MHD we get requested and actual rail pressure measuring blocks. I’ll see what I can dig up on Google.

injectors are very possible. I believe ISTA can run an injector test but I’m not 100% certain.
