Yes, AFAIK it's stock. Will BMW just replace the injectors if I ask?
Not just for asking but they will test them. You have to declare a problem first. If they find something "wrong" they will replace them. If they are making a lot of noise, you have a miss, bad running motor or engine light. Maybe fuel mileage but that's a tougher one. I think it's worth getting the car looked at for sure. Even for piece of mind.
