Hi guys
Drove down Cornwall and the last few miles the car list all boost, no noise, no bang, nothin just refuses to boost. No lights on the dash either so disconnected the battery overnight and still no change?
Can anyone help?
Cheers

How high does it rev? Is it capped, or will it go all the way? If it revs and there's no boost, I think you've got a massive leak, as a turbo has no choice but to boost.

Could be a dodgy recirc valve?

or just unplug the maf...
(ESP light will come on, and you will loose Traction control while the maf is unplugged)
it will run with slightly safer default settings using difference data, but would allow you to determine if the maf if the issue or not if it boosts ok unplugged.

Found the problem. Maf, and n75 were fine
Took tip off the turbo and it spun nice and freely. Checked the actuator to see if the wastegate was stuck open to font the two lock nuts had undone leaving the gate wide open!!!!
Closed the gate, nipped up the nuts and hey presto! BOOOOOOST!!!!!!!!
Cheers for help tho chaps
