Had an issue where I ran out of gas due to faulty tank level sensor. Replaced I tank pump assembly and replaced injector at the same time because it was time anyways. But now on idle it revs up and almost dies, hesitates when I try to rev it and sounds like it’s not firing on all cylinders. No cel. Had a lean code before injectors. That’s all I’ve gotten. Any help would be amazing!

Fuel filter? Best would be to check what codes are in the car using ISTA+. Not all codes show wirth the average commercial code readers. The code(s) may help you steer towards the root problem.

Using ISTA+ also allows you to check the fuel rail pressure and fuel pumps operation, along with the injectors

Any idea how where to find a new fuel filter. Can’t find anything on FCP Euro.

The only thing I have is this, but do not know exact location, etc. I recommend that you use ISTA (need an ENET cable) to diagnose and narrow down the problem instead of random troubleshooting. The problem may not be a straightforward "no fuel" or "plugged injector feed lines", etc. May also need calibration after all those replacements you did.

I did program the injectors. I’ll look into ista today. Thank you!

Recommend to ask for ISTA+ and the data-set here. https://f30.bimmerpost.com/forums/sh...16911&page=105

ENET cable needed (there may be cheaper cable options): https://www.amazon.com/Ethernet-Diag.../dp/B07FVN68JR
