Today I’ve done further research on my low boost issue. I’m running Cataclean through the system just incase there’s a blocked exhaust issue, I don’t think there is but just in case.
Anyway I read that disconnecting the yellow wastegate line to the boost control valve should create a huge swathe of boost….so I disconnected it and did a trial (gentle) run. Nothing. Bugger all just the usual barely into the white boost.
So does this point towards a duff actuator? The forum I was reading in the states then cured this by replacing the actuator, is this correct for all cases?
I’m sending the car in to my Subaru guy next week so I guess he’ll be able to pressurise the wastegate to establish if it’s working or not. I understand the T5R runs the same turbo as the Impreza TD04 so maybe my guy may have an actuator that will be swappable?
Amended to state actuator not wastegate
