Performance ES vs GT

[jamesy12345]

Yup, I twigged the b...££££ about the turbo but the company who reconditioned my turbo set the wastegate to open early. I have every confidence that when I have corrected the mistake to "half a hole" or around 5mm not the 1-2 mm movement of the actuator rod they imposed on me, some more power will appear. I unlocked the actuator rod, loosening the 10mm nut, removed the circlip and pulled off the rod from wastegate spigot. I tried to rotate the turnbuckle but could not actually move it. Locking compound or crimping??? Looks like a small dimple in the turnbuckle body.
What I am very interested in is the condition of the regulating valve. If this indeed triggered a fault in my Robou, then it will have to go back and be mended.
Would anyone have a known, proven, regulating valve I can buy from them please. It would be pointless to have the ECU checked to find the regulating valve may blow it again. I will, of course check the resistance as Robou suggested.
The red pipe from the regulating valve goes to a new diaphragm working the actuator rod. The wastegate is new.
The white pipe goes from the turbo area to the regulating valve. Let me know if the set up is erroneous.
This is all proving quite disheartening.

I replied on the 480 forum but repeated here...

Try using molegrips fella rather than pliers. Here's a schematic of the system



Top hose (black) feeds pressure to the solenoid, middle hose (red) goes to wastegate actuator. Yellow hose not so important. Colour references are to my photo, which may not match yours. If you suspect your boost solenoid it's resistance between pins can be checked...



...but if you have no luck I may have one somewhere
