15 Volvo D13H Turbo issues, part numbers?

Started the truck this morning and it had a really rough idle and popped up the code P004607 that shows as a turbo actuator code.

I have no clue what the turbo part number is since the plate sticker is half torn off on the turbo. I'd like to ask if I should replace the turbo or the actuator. Is there a way I can check to see if the vanes are sticking or if it is a bad actuator myself?

Truck has 508k miles on it. If I do end up having to replace the turbo can anyone give me a good part number for the one I need (dealer wants $4800 for just turbo with actuator)? Last 8 of vin is FN180531. I'd ask the dealer but the manager has a ####ty rule about not giving out part numbers.

Thanks

Nevermind. Looked closely at the actuator and noticed one of the wire had frayed insulation. Little bit of liquid tape and good as new!

 

That's my plan, omaha is the next closest dealer to me and they are an actual full volvo dealer rather than a subcontractor dealer like my local one.

I've had quite a few stupid wiring issues already so I think from now on I'll just start looking at wiring. Helps that ive got diagrams now for sure.
