18.4-1101a indicates the pressure sensor is at the base of the filter housing; that'd seem to be an appropriate place if you want to hook up a test gauge. TDM indicates that pressure may drop to .3bar at idle and should be at least 3bar at 3Krpm. 18.1-1101a deals w/ the oil pressure relief valve on the pump and indicates that control cuts in at 5.8bar. I'm wisless at the moment but it might just be worth a peek. Symptoms?
