Hello Everybody

My OEM turbo died in 98k miles so i bought some aftermarket BS from eBay for 440$. I bought k04.
It worked great for 2 weeks but today I lost power. Before I could hear the diverter valve (stock) and also I could hear the air going to the intake.
Today I don't hear DV and air so is that mean that my wastegate is stack open? Or maybe it is something different? Spring?
I would really appreciate if anybody could guide me
