About 54347193448 Hydraulic Tailgate Pump
Hydraulic pumps are used for hydraulic drive systems. Hydraulic pump is a mechanical power source that transforms mechanical power into hydraulic power. It generates flow with enough power to overcome the pressure caused by the pump outlet load.
The Convertible Top Motor helps to raise or lower the convertible's top. The convertible motor drives the pump which is connected to the motor at one end and the fluid reservoir on the other end. The pump generates a pressure varying from 300 to 450 psi. It is fitted in the trunk area and supplies hydraulic fluid to the lift cylinders which are mounted on either side of the vehicle.

I replaced the motor on my 2008 BMW Z4 with this part. It was an exact fit, except for missing one screw hole for the cable bracket. It worked immediately after the install. Longevity is to be seen.
