My indy guy told me to save my money and do one.
He said, if I had took it to BMW they would have changed them all along with the coils just to reap the benefits of the 3rd party warranty that I have.
If you can leverage your warranty provider into covering all of them, definitely do that as injectors aren't particularly cheap. If this is coming out of pocket, then it just becomes a question of how much you're comfortable spending. Do one for low cost and have it potentially be a short term fix until the next one goes, or bite the bullet and do them all to have the peace of mind.
