Guess I need a fuel injector

This is on my USA 328d.

Getting a code for fuel injector: P02D1

Sounds like it's partially clogged and the ECU has determined it can't make any further fuel trim adjustments.

What is the accepted process for this? Order a new one? Order four? Send mine off to be cleaned and flow-tested?

Is the process for swapping them easy? I'm guessing crack the fuel rail open a smidge somewhere to bleed off pressure and then unbolt, pull out, and replace?

Very easy to replace on these engines compared to older M57.
Just get a used injector and code IMA values with ISTA or other tool when you have the time.
Coding IMA value is not that important but helps to keep the adjustment values down.

Ultrasonic fuel injector cleaner is one of the best investments.

UPDATE UPDATE UPDATE

I bought a bottle of Archoil diesel additive and dumped the entire bottle in while filling up. The car runs quite a bit smoother now and the CEL is gone.

Lucky! Now make sure to use something like hot shots EDT every fill up, and their diesel extreme twice a year to keep the injectors clean.
