Thanks for the RealOEM suggestion. But the BMW service bulletin is saying that the parts catalog information isn't accurate and shouldn't be used.

The bulletin provides a process for determining what should be the proper part number. My concern is that of the two part numbers it lists, it's telling me to put in the one that's different than what the factory installed.

So do I trust the bulletin, or stick with what the factory installed? The injectors are expensive enough that I'd prefer not to be guessing which is right...
