Mk7 2012 2.2 125PS RWD is slipping into limp mode with MIL and Powertrain light on, generally when on high load up a hill.
Read codes: P0045 Turbo boost control solenoid open circuit.
The turbo on this van is, I believe, a VNT turbo (variable vane).
The vane angle controls the boost and the vane angle is controlled by the electronic actuator on the front of the turbo.
If this is all correct, is the fault telling me there is an electrical open circuit on the electronic actuator?
If so, does the whole turbo assembly require replacement?
Thanks,
Jon.
