Readiness: N/A

-------------------------------------------------------------------------------

I've been told that it could be any of these things:

- Faulty Pressure Converter Valve / Boost Control Solenoid (N75 valve?)
- Perforated diaphragm in the Vacuum (VNT) Actuator ?
- Sticking turbo vanes
- Faulty Intake Manifold (it's the plastic one, with the flaps) and/or Flap Actuator

The car runs well on the whole (throughout the rev-range) but has occasionally been down on power when cruising and trying to accelerate. It's only gone into limp mode once, before this reading was taken and I don't want it to happen again.

Can anyone help?

I don't think I have a DV? I've got the diesel BMN PD170 engine.
