Was racing other day, car was running well quick, no problems at all, came to a roundabout, pulled away normally when went to put foot down no turbo spool up at all. boost gauge doesnt read any boost pressure.
no smoke, any air leaks or engine light on, just drives as a none turbo now?
have eliminated ecu, boost controller and turbo actuator.
any poss causes?
im thinkin of takin down pipe off next to check wastegate arm/flap, could this cause this problem, even though never heard anything breaking up through exhaust?
cheers

no air leaks can be found or heard. im thinking map sensor before take down decat to inspect turbo? but why no engine light on if this is the case?

Similar thing happened to me, it was only the Cir Clip which connected the waste gate actuator rod on the turbo. Have a look see if the rod had come loose off the Turbo.

Or something has jammed in the turbo blades and is stopping it from spinning.

It's nothing obvious like a IC hose/hard pipe popped off/massive split, is it?

Are the turbo shaft bearings seized, might be worth a look ?
