Very loud injectors(possible wastegate rattle?) question

My 335i is under warranty until the end of October. Lately, as in the last two days, the injector ticking has gotten very loud and can be heard with the window closed. In addition, I hear what sounds like wastegate rattle at lower speeds( sounds like tin cans rattling in the hood). It doesn't seem to effect performance and no codes popped up with my obd tool. Im dropping the car off at the dealer on Monday. Aside from what I mentioned above, what should i look for when either describing the problem or talking to the mechanics to make sure that this can be fixed under warranty? What is the likely cause( replace injectors? replace fuel pump?). Its an 09 335i with 23k miles that has had the hpfp replaced, but other than that, standard maintenance. Thanks.
