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 |
