System venting (Allroad): Notes
WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2005 Audi allroad, 2004 Audi allroad, 2004 Audi A6, 2003 Audi allroad, and 2003 Audi S6. However, it is still accessible from the selected car via links, so may be relevant.
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)
