Cutters VAS 6228 00000 for cutting through pressure hose.

Notes on replacing pressure hoses

Note
^ Faulty pressure hoses can be replaced in sections.
^ Using a plug connection (see Spare Parts Catalogue), individual sections of pressure hoses can be safely joined again.

^ The pressure hoses are correctly fitted when the first color marking (self applied) is no longer visible and the second color marking is still visible.
^ To check that the pressure hose is fitted correctly, pull it slightly against the insertion direction. If it is fitted correctly, it cannot be pulled out or only pulls out when great force is applied.

The following points must be observed when choosing the repair point:
^ The repair point must lie in an area protected from water spray
^ The push-on connector must be fastened with tie-wraps to the structure or a cable guide
^ Straight pipe sections should be chosen for the repair
^ Position the pressure hose back in its original fastenings
^ Insert the ends of the pressure hoses firmly into the push-on connector.

Repair

Note: When filling the air suspension, the vehicle lifts.

1. Lift the vehicle.





2. To bleed the air suspension (air pressure must be allowed to escape out of system - if this has not already happened due to the faulty line), use the Porsche System Tester. To do this, select the menu item Bleed air suspension in the Air suspension system.





3. When repairing the pressure hose, cut off the damaged section squarely using the cutters VAS 6228 00000.





4. Mark the pressure hose to be replaced in color (e.g. with a waterproof marker). Measured from the cut-off end of the hose, make two colored marks at 16 mm and 22 mm respectively -(arrows)-.
5. Insert the pipe until the range between the two color markings min. 16 mm up to max. 22 mm -(arrows)- has been reached.
To fill the air system, use the Porsche System Tester. To do this, select the menu item Fill air suspension in the Air suspension system. Switch on level adjustment.
