Not sure if its possible, i wish, it was pretty straightforward on C7. Your only available option would be using the scan tool ODIS and word around here only shop that can do this is Pacific German. Or option 2, go with the traditional links or Cete. Nice SQ7 btw.

Can you provide the details on coding/adaptation changes?

THIS PROCEDURE HAS NOT BEEN THOROUGHLY TESTED AND SHOULD BE DONE AT YOUR OWN RISK!





So, the procedure for lowering / raising / calibrating the level control / chassis control on your Q7 4M (and probably other platforms) with VCDS is work in progress.

Put this on the Ross-Tech Forums as well, hoping that someone with more skills than me will be able to get this all the way across the finish line...


[NOTE] This procedure is verified to the degree that it works, but I’m stuck with 1 DTC that I’m quite certain I’ll find a solution to quite quickly.


Important Preparation


-Min 50% Fuel level

-Car on level surface

-Suspension to Auto

-No people or things in the vehicle (Laptop outside and wire through window if applicable)

-Doors shut through the process!



Then;

Select - [74-Chassis Control ]

No security access required.



[Basic Settings - 04]



- Choose - [Activate level control] - Press [Go!]

- Wait for basic Settings to End (Finished Correctly), then press [Stop]



[Basic Settings - 04]


- I’m quite certain this step can be skipped, but it doesn’t do any harm to my experience.

- Choose - [Delete calibration for level control] - Press [Go!]

- Wait for basic Settings to End (Finished Correctly), then press [Stop]



[Basic Settings - 04]

- Choose - [Set reference level] - Press [Go!]

- Wait for basic Settings to End (Should run for 30 seconds or so), then press [Stop]


Measure the ride height, in millimeters, from the center of the wheel to the edge of fender, do this for all four wheels and record the values.


[Adaptation - 10]

Choose from the drop down menu and enter the [New value] recorded value for each of the wheels below, then press [Do it!]


It’s important to do this top to bottom, or you’ll get an out of sequence error and almost certainly be back to square one:

- [Body height left front wheel house edge] mm

- [Body height right front wheel house edge] mm

- [Body height left rear wheel house edge] mm

- [Body height right rear wheel house edge] mm


To lower the car, add the desired number of mm. To raise it, subtract from the recorded values. Out of range values will throw a DTC on the sensor and a sequence error on your next attempt (square one).


For the Q7 4M the standard values are as follows:

Standard 1BK suspension: 442mm front and 454mm rear.

Sport 2MA suspension: 427mm front and 439mm rear.


I found that the maximum values that my Q7 4M would take without DTC was 446mm front and 459 rear.


[Basic Settings - 04]

- Choose - [Calibrate level control] - Wait for basic Settings to End (Finished Correctly)?


[Basic Settings - 04]

- Choose - [Activate level control] - Wait for basic Settings to End (Finished Correctly)?



[Basic Settings - 04]

- Choose - [Switch to normal level control] - Wait for basic Settings to End (Finished Correctly)?



My experience is that basic settings won’t always finish correctly. Some times the do, some times they don’t. The end result could still be success. I always exit the module [Basic Settings] or [Adaptations] between every single input, as that seems to lead to fewer

Measure the ride height again and verify the values are within 3mm of the displayed values in Advanced Measuring Value Blocks.



[End of (Draft) Procedure]



As mentioned, I still have the one DTC left - C1046 F6 [137] - about the axle load determination not having been performed. That also comes with a nice yellow warning light and some music to go with it as you start the car.



All values are accepted, though. The system works problem free on all levels, and my car is approx 21mm lower than it was yesterday.





PS: - I also cleared DTC’s every time I exited Basic Settings or Adaptations, prior to re-entering either or.

- Trying out of range values will throw DTC’s. They can be cleared, but you’re back to square one. The max values that my car would accept w/o fault are noted above. These will vary, and I even experienced difference between left/right on the same axle in terms of accepted (and permanently DTC free) values.

- As you go through entering the values in Adaptations, it happens around 1 out of 3 times that you can’t get through all 4 wheels before you get a sequence error. Exit, exit, exit, ignition off, breathe in, breathe out, ignition on, start from the very beginning….

- There is an option called Calibration of level control for axle load determination in Basic Settings, but trying it only gives an ERROR: Conditions not correct or request sequence error - Possibly due to the lack of a functioning security access key?


The following keys have been tried unsuccessfully: 20103 - 31564 - 40168 - 20113 - 12345
