Hi and welcome to the asylum , lol

I’ve got a D3 but can looks those codes up for u, will post them up in a bit
 
@Bear LR

Here u go

P006A = Manifold absolute pressure – mass or volume air flow correlation
P00BD - Air-mass meter or air-flow sensor
P023594 Turbo sensor

First thing to check would be for a cracked inlet manifold or may be a turbo issue , know that’s not much help

Alas I’ve not got a D4 but the guys here are very knowledgable

I have had a look at inlet manifold's, 2nd turbo isolation valve, MAF clean, when the engine reeves up to 1800 RPM and higher, than decreases 2nd turbo inlet manifold flows air through the second MAF into the air box with a squeal like sound, the 2nd turbo inlet control arm is free moving.
