Does anyone know if the same engine driven hydraulic pump is used for all 3 hydraulic options? In other words does Porsche Dynamic Chassis Control, Rear Wheel Steering, and Front Axle Lift all get their pressurized hydraulic fluid from one source? I ask because if I end up ordering RWS will I only need to worry about the maintenance or repair cost of one hydraulic pump and reservoir if I decide to also add FAL and/or PDCC? Thanks.

RWS has electric motors I believe. One on each side.

PDCC has its own reservoir and pump ( fluid change at 60000 miles).

Don't know about FAL

RWS, check. Electrical actuators at the rear wheels.

PDCC, check

FAL has its own electrically driven pump unit and is a closed system. No fluid service possible. (Ref: Porsche Engineering Magazine 2016-2)

Ooops.. re-read article. There is a fluid change possibility but no interval is specified.

GTSMeister, great information. Very helpful to know each system stands on its own with regard to adding them to a build. I did find the cost of servicing the PDCC system in a previous post. Not sure anyone has had their FAL fluid serviced, but I would imagine it is less complicated than servicing the PDCC system. Thanks for the quick reply.
