I need to change the rear air shock absorbers on my 2006 A6 Avant, which has the adaptive air suspension system. in order to R&R these shock absorbers, the system needs to be bled of its pressure. I found the previous post re: this subject (http://forums.ross-tech.com/showthread.php?1996-Level-Control-Bleeding-Charging) and attempted to follow the directions using my VCDS. However, the module 34-Level Control on my car does not have the "Login-11" button, and the "Coding-II" button is greyed out, i.e., inaccessible. I do have one button that is labeled "Coding-7", but I am not sure this button replaces the "Coding-II" button. How do I use VCDS to bleed and charge the air suspension system? If the "Coding-7" button is to be used, what field would I enter the "08367" value (assuming that is correct for my A6) listed in the referenced thread? FYI, the protocol is "CAN" for my A6 Avant. Thanks.
