So I think I've got the N54 waste gate rattle. When the DCT changes gear or I'm at 50% throttle in gear there's a loud tinkling/ratcheting from under the car. Doesn't do it at idle but then I've had the software fix some time ago.
I don't think it's the exhaust flap as I've had that before and it's a different noise.
Really sad about this as I never seem to catch a break with this car.
As I'm on insured warranty unless something breaks it won't be sorted so rattles are rejected.
So I've got to ride around with this noise until something goes bang at which point while left stranded I may be able to claim under insured warranty.
Boring Lexus is in my future I think. I can't stand all the problems I've had with my two BMWs.
