    Retrofit Air Suspension to Q7 (4L0)

    I'm in the process of retrofitting OEM air suspension to my 07 Q7.

    I've got all the wiring done, the module connects and reads properly. I've coded it in with under the CAN gateway, but I need help with the following:

    - ABS is throwing codes saying "module coded incorrectly" and there is no coding helper for it.
    - I don't have the Air suspension menu in the MMI, and can't get into the "green menu". It's coded and enabled but the two-button trick doesn't work.
    - What other modules do I need to code to fully add the air suspension?

    I apologize that I don't have the required auto-scan, I borrowed my friend's VCDS and had to return it. I may be able to get it again this weekend, at which point I will scan and post it.

    We'll definitely need sight of the Auto-Scan...

    Here is the scan:

    Removed.   Data from a clone/pirate copy of VCDS is not welcome here.

    Your friend has put you in rather embarrassing position.

    Was he also the one who patched current header data into a scan from an ancient version?

    In any case, getting help in this forum requires the use of a legitimate VCDS system.

    They are available directly from us:
    https://store.ross-tech.com/shop/cat/VCDS

    ... Or from any of our authorized resellers:
    http://www.ross-tech.com/distributors.php

    Let us know if/when you get one and we'll adjust your forum status.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    No that was me, and you're right I am embarrassed. He lives 2 hours away and I was selfishly trying to save myself the drive. I'll try again later this week, sorry about that. Learned my lesson. I am humbled.
