Why it happens

Likely root causes behind P2581

Hot-side geometry binds from soot and high EGT exposure.
VGT actuator worm gear or position electronics fail after fighting a stuck vane pack.
Oil-cooked centre cartridge and worn turbine shaft bearings after hard shutdowns.
Oil seal leakage sends oil into charge pipes or exhaust.
