It always troubles you when the experts are kinda guessing... 'we see this before and changing injectors helps'... I assume that the dealer was talking with BMWNA/PUMA and got approval/instructions from them. Which means that the experiences of others are helping with your car.

I'd have liked them to replace all injectors- if there was a mfg issue, I want a new lot of matched injectors... too late for that, but keep it in mind if there are more misfires.

This CAN be serious, if an injector fails and fills a cylinder with fuel. But that is why it has a 'deactivate' function I am guessing.

In terms of 'will something else happen' or 'did they get it right', just give it time. I expect that it will act up soon if issues remain.

Keep it as simple as possible...but no simpler.
