Rattling coming from Waste Gate.

[dreamerx5]

I have posted several threads here and bimmerfest about the rattling noise coming from my BMW X5 35i. After taking my car in at leat 6 times to the dealer, they finally determined that the noise coming from my car is the Waste Gate. The rattling sound appears as when you start the car and at the Under load. You can only hear it when you have the windows rolled down.

Apparently, there are other owners that have the same issue but are not bothered ny the rattle. My resonse to that is "WTF". How does that not bother you??? My $70,000 car sounds like a Lawn Mower!!!

Now that we figured out where the noise is coming form, i'd like to ask if anyone hears this and if this bothers you?

Probably means a turbo waste gate, it's a well documented issue on the N54 motor I believe...

wate gate from the turbo. It really bothers me a lot. Im assuming that you can not hear this.

I'm not sure if it's the wastegate,but when I cold start it the rattle from underneath the car sounds like a can full of coins.

Pretty sure that's the wg,but it's quiet once warmed
