Hey guys, I'm pulling my hair out on this. I have a 2006 jetta tdi BRM and I was getting excessive oil in my intercooler pipes and I was afraid my turbo was going to detonate. So I replaced the turbo cartridge. Upon reinstalling when I start it if I hit the accelerator immediately the turbo will boost like it should. But if I let off it goes into a sort of limp mode and won't boost or get above 1k rpms. It is all stock other than an egr delete. I'm also getting a P2564 code. Does that mean my actuator needs replaced? Thanks for the help.
