1.4 TSI GT 170 - Boost Control Valve & Turbo Issues

[TwebbGBC]

Hi everyone, so after 3 months of the same issue and trying to get it sorted im beginning to lose my mind doing it.

I've had the following error codes for quite a while now:
08196 Intake Manifold Flap Bank 1 Stuck Open P2004
00579 Solenoid Valve (A) for Boost Pressure Control (N75) Malfunction P0243 - Intermittent

I've scoured parts left and right and I finally managed to find an Intake Manifold (from Latvia of all places) but I've bought two different valves and they have both said they're for my car, but they don't fit. Here's an Imgur album for pictures of the Valve and the Fault Codes: https://imgur.com/a/sTrwCtA

Does anyone have any advice or know the exact part I need. Let's hope third valve is the charm!
