Technical Notes
The HE551W turbocharger is a variable-geometry unit where the actuator controls the turbo details to manage boost pressure. For this specific 4044721 replacement, verify that the actuator related hardware geometry and mounting details match your existing unit. Confirm the engine code (MD16, D9, or MD9) and production year against your service documentation. Do not assume universal fitment across all HE551W variants; check the OEM reference numbers on your current part to ensure the diaphragm and housing dimensions align correctly before installation.
