Okay, so 10 & 12 were in the wrong order on the manifold end. And the ecv or iav both didn't move.
I swapped those to their right spot. Went for a drive, iav and ecv both began working in diagnostic mode. But I'm still having the cut out at about 3k revs and boost was about 2/3 psi.
So at the moment.
ECV is working
IAV is working
1 is correct
2 is correct
3 is correct
4 doesn't exist
5 is correct
6 is correct
7 doesn't exist
8 is correct
9 doesn't exist
10 is correct order onto manifold
11 is correct order onto manifold
12 is correct order onto manifold
21 is correct
22 is correct
23 is correct
However, 10, 11, 12, is where the B4 diagram differs from the gen2 (BG5) TT.
12 has a T piece that runs through an air filter into the firewall. This line into firewall is numbered, but looks correct?
Both 11 & 12 are on the correct pipes across the top of the manifold.
10 travels across the top of the manifold and drops into the air intake before the primary turbo, and Ts off into the guard. But my 10 looks like the hose \10\ diagram.
I also have an extra pipe which comes from the passenger side off the manifold which has no home/ doesn exist on your B4 diagram.
This is a BG5 TT.
