Yeah i brought my car into the dealer but i had my aftermarket mufflers on. And i had cut my stock ones off. They always worked on the car when i had them on. But this time they wouldnt do it. I got a stock exhaust now so im hoping theyll fix the problem. I cant take that rattling sound and the lag anymore.

Yeah, I took off every engine mod that I had, left all the suspension, no hassel, went through the series of test they proceed through, resulting in new turbos....GL

best way to check is to simply reach down into the engine bay and check the play on your wastegate rod....

but if you don't feel like it, the rattle will be present even at driving temps, so you may have nothing to worry about

Ohhhhh, that's what it is. I started hearing a faint rattle on acceleration two days ago. Luckily, my tune, intake and exhaust are Dinan, so I won't have to take my car apart in 20 degree weather.
