System venting (Allroad): Notes
It is possible to perform a ventilation of the air spring system without having to loosen mechanical connections.
System filling via On Board Diagnostic (OBD) must only be performed with the vehicle standing!
WARNING:
By venting the air springs, the self-supporting vehicle lowers itself!
NOTE:
- The air spring system (pressure reservoir, air springs, pressurized air lines) can be vented up to the residual pressure of < 3.5 bar via VAG tester.
- Venting the pressure reservoir is possible without entering a login code (display group number 20 - 21).
- Venting the air springs is performed separately for front /rear, where the correction login-code must be entered right away (display group 22 - 25).
- Venting is only possible after manually switching off the regulation. Switching off and on of the regulation is performed with the VAG tester (Fct. > 10, channel 10) or via manually pressing button for up and down (press button twice > 5 seconds).
- Time frame for venting is limited to 65 seconds. However, it is possible to perform the function several times in sequence to accumulate a longer venting time.
- It is possible to perform a filling procedure in stages using the up and down arrow buttons of the VAG tester.(buttons 1 / 3 of VAG1551 tester have the additional assignment downarrow - button / uparrow - button)
