E46 M3 SMG II Pressure Sensor

This is a NEW replacement pressure sensor.

The pressure sensor is located on the block of the hydraulic unit and it measures the pressure of the hydraulic fluid. Due to the location of the sensor the instrument usually fails as a result of the excessively high ambient temperature within the engine bay, damaged pins from user installation and/or corrosion. 

A damaged sensor with incorrect pressure readings will make system go into error state and can overstress the electric motor. The feedback from this sensor is critical to system operation.
