PTP - Pneumatic Test Program

Preparation for Test:
1. Review Connection and Use of Test Equipment,
2. Review General Information, Version Coding, Diagnosis, DTC Memory, Recalling Actual Values, Component Locations, Connection of Components and Preparation for Test.

DATA (mbar)
Test procedure
Allowable System leakage at 600 mbar pressure or 300 mbar vacuum in 1 minute: Permissible deviation <= 30mbar

Allowable leakage of actuators with lines at 600 mbar pressure of 300 mbar vacuum in 1 minute: Permissible deviation <= 25mbar

Special Tools:

A. Entire System

Preparation for Test:
1. Provide access to PSE control module (A37) and disconnect yellow pneumatic line with socket from PSE control module.
2. Connect tester to disconnected pneumatic line using with connector 129 805 03 44.

NOTE: 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 Connection 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 Steps 1.0 - 2.0:

B.Individual Lines With Actuators

Preparation for test:
1. Disconnect pneumatic line leading to the non-operating pneumatic actuator at the pneumatic distributor. Letters on the distributor indicate to which of the CL actuators the pneumatic line leads.
A-> Left front door
B-> Right front door
C-> Left rear door
D-> Right rear door
E-> Fuel tank filler flap
F-> If Trunk lid

NOTE:
1. If an actuator does not operate correctly and no leakage is found, check the respective lines for kinks or blockages.
2. Disconnected pneumatic lines are to be reconnected to the distributor with connector 007 997 61 82.

Parts required for test:
1 Pneumatic hose, 50 mm long 007 997 61 82

Parts required for repair:
1 Pneumatic hose, (as needed) 007 997 61 82

Test Steps 3.0 - 4.0:

C. Actuators

Preparation for test:
1. Remove nonfunctioning actuator.
2. Connect vacuum/pressure tester to pneumatic connection of actuator.

Parts Required for test:
1 Pneumatic line 129 800 95 15
1 Pneumatic line, 1 m long 000 158 14 35
1 Pneumatic hose, 50 mm long 007 997 61 62
1 Connector 202 805 03 44

Test Steps 5.0 - 6.0:

D. Lines

Preparation for test:
1 Connect tester to one end of pneumatic line and plug other end with cap 000 987 29 45.

Parts required for test:
1 Cap 3000 987 11 45
1 Pneumatic hose, 50 mm long 007 997 61 82

Test Steps 7.0 - 8.0:
