As asked does it come back with injector unpluged?
I would be working on the code if it keeps coming back.
Get the repair flow chart for that code and go threw it step by step.
A factory repair manual or the all data sub.

The all data on line sub has code repair flow chart and should have the VCM pin outs and pin test.

Also scroll down threw the post there was a link to a free libary lin posted if you want to try it for info.

And some one will help you.
Give all info.
Engine and engine code.
