BMW is using a newer injector now and if you replace one in the bank then all 6 have to be replaced if you have the old ones. I took my car in last month due to misfiring and they replaced one bank of injectors (eventhough I only had one bad injector). Luckily i had a misfire in the other bank when they tested the injectors and they replaced my other bank of injectors.
