Test 1: Retractable Trunk Lid Grip System Pressure Check

Disconnect pneumatic line from retractable trunk lid grip actuator. Connect Yellow connector on Vacuum/Pressure Tester (201 589 13 21 00) to pneumatic connector on actuator and plug actuator throttle on trunk lid grip actuator. See Figure. Apply 8.7 psi (600 mbar) of pressure to actuator. If pressure loss is not substantial in one minute, actuator is okay at this time. If pressure loss is substantial in one minute, replace actuator.
