Help please

Ok a few days ago I replaced the VNT actuator because of the P00AF code, and limp home.

After I replaced the actuator Now I get P2563 code, Flashing glow plug light and NO limp home. What could be the issue?

I am completely lost I think the wires on top of the VNT are not seeing what they should be seeing as that is really the code.

So Help Please!

Soo what did you end up doing to resolve this issue. I'm in the same boat.Thanks

Ok I replaced the VNT and it has to be set correctly so the 2 screws on the threaded rod needed to show the correct voltage. I was off only about 1 or 2 turns on the VNT install.

So, After replacing the VNT part number 03L-198-716-A I had to go back and set it correctly with this
