Pneumatic Test Program - Test (RTR)
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 RTR control
valve (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).
