Ok, i know a lot about the wastegate rattle (and actually slightly have it... :sigh:) but i've encountered another problem also...
Every time after starting the car (especially cold) and making a first firm pull, i can hear a loud metallic harsh sound from exhaust when changing gear up, usually from 1->2 (AT). When changing from 2->3 right after everything is normal. I think it has to be related to the turbos as it need a bit of boost to happen. When driving "normally" i cannot hear it.
- It cannot be the buterfly valve as it has been removed
- all vacuum / boost lines have been changed
- no fault codes
- JB4, stock pipes
Any ideas? The car looks amazing now after all updates and the sound makes it feel like a 6$ shitbucket.
