Please forgive me for arriving late and joining the conversation after all the great info already posted, just thought this would be the place to get real world, first hand knowledge on the turbo/waste gate debacle. First off just purchased my first BMW
, a 2007 335i, LOVE it! After a few days of driving the car i have realized this "rattle" under the hood. To my surprise this IS a common issue. Also, on a side note (because it was also mentioned in this thread), the HPFP is another warranty piece? Long story short my car is mint with 65,xxx on the clock. I have an appointment to take the car back to the dealer monday to have the rattle looked into. Should the service dept. already know about these problems and fix them? Does my car fall into the warranty category? Thank you in advance for any and all helpful info. BTW new to the forum and love it!
