Hello,
I've recently cleaned the VNT vanes on my 1.9 TDI BLS due to an overboosting issue. The vanes were heavily caked and difficult to move. After reassembling everything, the car now runs poorly and produces a lot of gray/black smoke. It struggles to rev to 3,000 RPM, and sometimes even to 1,500 RPM. However, when I disconnect the VNT vacuum hose, the car runs normally and boosts as expected, which is puzzling. There are no fault codes present.
How vacuum hoses are currently connected: Could this be due to something I did during the reassembly, or could it be a faulty VNT actuator or N75 valve?

The engine is a 1.9 TDI PD (105 HP) BLS.
Thanks in advance for any help, guys!
