Lowering AAS with VCDS
1) Set your car to "Auto" mode (not dynamic, comfort, etc.). Make sure car is on level ground. Close doors. If any
doors are opened during the procedure, it will be interrupted. Make sure your car is NOT in a towing or tire
changing mode.
2) Load up VCDS, go to Module 34 ‐ Level Control
3) Go to "10 ‐ Adaptation", take note of 4 values titled as "Body height front left wheel house edge" ‐ mine were
set to around 384 from factory.
4) Take the values you noted above, and ADD your desired drop in millimeters (mm) to each value, write it down...
So if your left front wheel was 384.5, your new value will be 401.5. Repeat for the other wheels. It is not critical
to be 100% precise here, rounding the values is fine. Note that maximum Audi‐approved drop is 17mm from
what I've gathered. You can go lower, but if you go lower, you're also affecting other systems, such as cameras,
adaptive cruise, etc., so be careful.
Technically, if you want this procedure to be done properly, instead of taking existing values, you will measure
all 4 wheels after completion of the step 7, and then add your drop value if desired. Suspension height values
are measured from the center of the wheel to the edge of the fender.
5) Go to Security Access, enter code provided on the following website, under VCDS section, item #3 (I'm not
posting this directly to avoid spreading sensitive data, although it's been posted on other forums in
past)

6) You should get a message stating that security code has been accepted ‐ if you don't, something failed, stop
doing what you're doing
7) Go to 04 ‐ Basic Settings
*** IMPORTANT: Whatever you do, DO NOT select "Reset All Adaptations" ‐ this is not undoable, and will
require a visit to a dealer. ***
8) Select "Activate Level Control", hit "Go", wait for it to complete (should only take a second, until it says "not
running").
9) Select "Delete Level Control Calibration", hit "Go", wait for it to complete, your car will throw a fault code and
you will see an error message stating Air Suspension Malfunction ‐ this is normal.
10) Select "Start Up to Reference Level", hit "Go". This step will take about a minute, and your car will go up/down
during the process (you'll hear hissing noises). Wait for it to complete, until it says "not running"
11) Select "Go Back", go to "10 ‐ Adaptation" on the previous screen.
12) Next you will need to enter new adaptation values for all 4 wheels. Select "Body height front left wheel house
edge", then enter new adaptation value, and hit Test or Save, whichever is available, and repeat for the other 3
wheels. I did it in the order the menu was arranged (FL, RL, FR, RR) ‐ not sure if the order matters, but just in
case. Each time you enter a value, you should get a message stating that it has been accepted
13) After you're done entering adaptation for all 4 wheels, select "Go Back", and return to "04 ‐ Basic Settings"
again.
14) In basic settings, select "Calibrate Level Control" and hit go, it will take a few seconds. Wait for it to say "not
running". If you get an error during this step, you either missed a step, or something went horribly wrong.
15) Select "Activate Level Control", hit "Go"
16) You're done, now go to "02 ‐ Fault Codes" and Reset codes.
