Wired sound when accelerating, possible air leak

Hey
I own a 2010 x6 35d, first owner, with aprox 240.000km

Last week I changed the intake manifold, large thermostat, glow plugs, a small oil pipe from small turbo(the one oil pipe above), 2 water pipes, gasket from egr and throttle valve(between them), gasket from vacum pump, gasket from air intake that goes in throttle valve.

2 days later a strange noise appeard, like an air leak when I accelerate, and is coming from driver side. At idle is no sound. The acceleration also is with low boost, like from 1800-2000rpm

Error appear only if I accelerate over 3000rpm
Check engine emissions incressed, fist time
4530 boost pressure control, control deviation
3FF1 air mass meter
483D Throttle valve actuator

Secone time
Check engine incressed emissions
3F25 3F25 charge air hose monitoring
3FF1 3FF1 air mass meter
4530 4530 boost pressure control, control deviation
483D 483D Throttle valve actuator

On 8.1.2025 the service will start working again.
Any guess?
I feel like a air intake leak, don t think that the new intake manifold craked( is Piersburg) maybe a air intake tube
