I am getting some wicked rattle. If I pull off the belly pan and Jack the car up wil I have access to the turbos from the bottom to check out the wastegate arms and try tightening them?

Well got the car up on stands and removed the splash shield by passenger axle to gain access to rear turbo. The rear wastegate arm I can rattle by hand. I think I need to adjust the arm and see if tightening helps at all otherwise I'm going to upgrade to GC lites this winter.

Mine rattles too, can rattle it by hand. But it seems to be the rod connection, not the actual waste gate.

I'm getting a 30ff code, have since I bought the car. Wondering if the rattle is associated to the under boost I get and not reaching target boost pressure.
