Dan648v:
Take it to a garage and get them to vacuum test the actuator. That'll tell if it's working, that's what my Audi tech did  :happy2:

cutchie:
So thought I would update this I've now replaced the turbo and the fault is Still the same still peaking at 4psi every time anyone any other ideas?

Dan_FR:
4 psi is about actuator pressure when measured at the inlet

Data logging with VCDS is needed need to check all readings and whether the ECU is requesting boost (N75DC% - block 116 from memory - or thereabouts)

cutchie:
003



114



115

cutchie:
these are the graphs I logged but tbh I don't really know what im looking at or for! lol does anyone else see out anything out of place?
