BMW E46 E60 E63 E64 E85 330I 525I SMG I HYDRAULIC UNIT PUMP ASSEMBLY 23427571297 23427507107

Description

The BMW SMG Hydraulic Pump Assembly (Part numbers: 23427571297, 23427507107, 23017568176) is a new OEM replacement complete with hardware and seals. This pump plays a crucial role in the SMG system by building hydraulic pressure for clutch actuation and all gearbox shifting. Failure of this component can result in erratic transmission and drivability issues, including misshifting, failure to shift, and prevention of the vehicle’s engine from starting.

Typically, the SMG pump motor will undergo wear and fail internally between 60,000 to 80,000 miles, dependent on driving habits. It is recommended to replace the relay concurrently, as it often gets damaged over time and could potentially short out the new SMG pump.

This assembly is compatible with a range of BMW models including the 325Ci, 325i, 325ti, 330Ci, 330i (1999-2006 E46), 525i, 530i, 545i, 550i (2001-2007 E60, E61), 630i, 645Ci, 650i (2004-2007 E63, E64) and Z4 (2002-2005 E85), all equipped with SMG transmission.
