Preliminary work: PSE control module voltage supply 23 PSE 1.0, 2.0 PSE Control Module Test 32 PSE

Data (mbar)

Test procedure	Permissible deviation
Allowable system leakage of 300 mbar vacuum in 1 minute.	30 mbar
Allowable leakage of actuators with line at 300 mbar vacuum in 1 minute.	25 mbar

Preparation for Test: 1. Disconnect yellow central locking (CL) pneumatic line from PSE control module. 2. Connect tester to disconnected pneumatic line using connector 202 805 03 44. 3. Remove trunk lid lock, do not disconnect pneumatic line. 4. Apply battery voltage to electrical connector of remote trunk lid release switch (Y65/3). If an actuator does not operate correctly and no leakage is found, check the respective lines for kinks or blockages. Parts Required for Test: 1 Connector 202 805 03 44 2 Rubber hose, 50 mm long 007 997 61 82 1 Pneumatic line, 1 m long 000 158 14 35 Note: The connections on the PSE control module and pneumatic multiple connector are marked with their German acronyms. In other words: ZV (German) = CL (English), SRU (German) = MVA (English), OSL (German) = OSB (English).

	Test scope	Test connection	Test condition	Nominal value	Possible cause/Remedy
1.0	Complete system pressurized	Yellow connector on tester to connector	Apply 600 mbar pressure to entire system.	Pressure loss 30 mbar in 1 minute.	2.0, 3.0

Preparation for Test: 1. Disconnect pneumatic line connected to connector F of pneumatic distributor. 2. Connect tester to disconnected pneumatic line using rubber hose, part no. 007 997 61 82. 3. Remove trunk lid lock, do not disconnect pneumatic line. 4. Apply battery voltage to RTR control valve (Y65/3). After testing, reconnect prior disconnected pneumatic line using rubber hose part no. 007 997 61 82 to pneumatic distributor. Parts Required for Test: 1 Rubber hose, 50 mm long 007 997 61 82 Parts Required for Repair Rubber hose (as necessary) 007 997 61 82
