RPM creep?

It's not on the pump itself. There is a solenoid on top of the engine kind of under the manifold in front of the turbo. It attaches to that shiny bolt in the centre of this pic. The plate below the turbo is blocking the tube that goes down next to the uppipe which would usually open up to the head.

Heaps of useful pics in here. You'd replace the turbo side solenoid if the baro sensor was dead, not the pump itself. Find a logger/reader to check the baro pressure before forking out for a new one though.

nice, thanks for that clarification.

This pic also clears it all up for me, matched up to yours.

Thanks! Ill report back once i figure out how to check the pressure.

maybe while im down there (if i need to fix anything), ill go ahead and take out my banjo filter too. I assume i see it in your photo just left of the attachment for the solenoid...might be different on my 08.
