Hello....

Revised 7/1/2020
- Streamlined [The Procedure] below, again, thank you ALL for your feedback!



This procedure is not for the 'older' non UDS vehicles, this procedure can be found here, 'Suspension Level Calibration'

How can you tell if you have a 'UDS' Level Controller? Click here UDS vs. Non-UDS
This is an example of a UDS Level controller when found in the Auto-Scan results:

Address 34: Level Control (J197) Labels: 3Y0-907-533-V1.clb​

[Coding]
- If there is an 'incorrectly coded' fault in the [34-Level Control], the controller will need to be coded first, before 'The Procedure' below can be completed!
- If you have saved an [Auto-Scan] of the vehicle prior to the coding being lost, you can search the scan and copy/paste the coding into the controller.
- In the unlikely event you have lost coding, create a new Ross-Tech forum thread in the Car Repair Support section and let's see if we can help.


Special Notes, warnings, etc
- Do not at any point in time select Basic Settings [*IDE01475*] [Resetting of all adaptations]. If you choose to do so, DTC B2013 will be stored and you will need to make an appointment with your local dealer! B2013: No End-of-Line Programming will prevent a successful calibration.
- Make sure you perform and save an [Auto-Scan] before beginning any work
- If you are attempting to alter the ride height use this procedure at your own risk!
- If you copy or post this procedure and/or any of its contents anywhere else, please be respectful and give credit where credit is due



[The Procedure]

------------------------------------------------------
- Re-adapt Adaptive Suspension to default position -
------------------------------------------------------

Prerequisites
- Ignition [ON], Use a Battery maintainer
- Vehicle on level surface
- No persons or gear in Vehicle
- Fuel Tank 50% or more
- Nothing under vehicle
- Door are to remain shut during the entire procedure

Using the MMI (under [Car]/[Service] ) the following needs to be set-
- Air Spring Wheel Change set to [Off] or Air Suspension Wheel Change (if applicable)
- Audi Drive Select (under Car menu) set to [Auto]
or
- Automatic Drive Program set to [Auto] (Bentley)
- Jacking mode, must be set to [Off]


1) Select - [34-Level Control]
Press [Security Access-16] enter - [20103], [Do it!]

2) Select - [Basic Settings - 04]
- Choose - [*IDE03751*] [Activate level control]
- Wait for basic Settings to end, [Finished correctly/Not Running], then press [Stop]

3) Choose - [*IDE03761*] [Delete calibration for level control] - Press [Go!]
- Wait for basic Settings to end, [Finished correctly/Not Running], then press [Stop]

4) Choose - [*IDE03802*] [Start up to reference level]- Press [Go!]
- Note, basic Settings [*IDE03939*] [Start up to reference level (production)] should NOT be used.
- Wait for basic Settings to end, [Finished correctly/Not Running], then press [Stop], [Go Back] (vehicle should level it's self wait till it stops)


5) 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, this will set the ride height to the factory level.

Notes:
- Modification to ride height may be possible, for example adding to the measured value would lower the suspension because the level control system thinks the ride height it too high. DO THIS AT YOUR OWN RISK!​
- We do not suggest anyone to make changes to the standard ride heights!​
- Users may post their 'tweaking ride height' questions here, in the Ross-Tech forum, Tweaks section.​




Select [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!]
-
[*IDE02001*] [Body height left front wheel house edge]
-
[*IDE02002*] [Body height right front wheel house edge]
-
[*IDE02003*] [Body height left rear wheel house edge]
-
[*IDE02004*] [Body height right rear wheel house edge]

See the above table for standard values

6) Select - [Basic Settings - 04]
- Choose - [*IDE03762*] [Calibrate level control] - Press [Go!]
- Wait for basic Settings to end, [Finished correctly/Not Running], then press [Stop], [Go Back]
(Vehicle may lower/raise)

7) Select - [Basic Settings - 04]
- Choose - [*IDE03751*] [Activate level control] - Press [Go!]
- Wait for basic Settings to end, [Finished correctly/Not Running], then press [Stop], [Go Back], [Close Controller]



Quality check and house keeping:


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

B.) Using the MMI verify the following setting -
- Air Spring Wheel Change = [off]

C.) Ignition Key On/Off Cycle must be completed.

D.) Clear ALL fault codes and re-check for fault codes, road test vehicle.



Reference:

- You may have one or more of the fault codes listed below...
403201 - Function Shut-Off Active
C10C8 00 [009] - -
403200 - Function Shut-Off Active
C10C8 00 [008] - -
367877 - Ride Height Not Learned
C1044 00 [009] - -
266752 - Control module not coded
U1013 00 [009] - -


Again, feedback is welcome and you are encouraged to post your experiences here in the Ross-Tech forum.

Thank you and as always, hope this helps,

drpeter

Small item, there is a redirect file, so label file should probably be 4G0-907-553
Are you sure odis use that many logins?

Hi...

- The last time we received positive feedback, I had a caller on the phone and we did run through the rough draft of the procedure, it appeared that before each of the Basic Settings functions would complete successfully only if the Security Access was used.

That is a good question though, is ODIS actually doing it the same way with the SA codes?? We have not tested that, ..yet. ;)

Thanks,

drpeter

Yeah well this locked thread linked above is a great example of what not to do or how to act.

The process above from Dr. Peter for me works very well in this thread.

FYI: When I have tested it and I can confirm that sometimes sessions get dropped, further requiring a login again due to bad connectivity, otherwise it streamed right through.

ADVANCED USERS!

MANUAL RESETS........

When after readings were in fact erased.
I was able each time to input them by setting the sensors to full high in service position. I do this by disconnecting on lift and reinitiating the test path to do a final save.

I find in some cases it is needed to have a second tech in the car to switch the ignition terminal 15 fast & between saving settings to eeprom in some controllers in steps or using a hand trigger wired if by yourself because there is limited time to lower car and get to the tester or switch!

While some controllers will allow for function tests, adjustment or a first adaption to commence, you will find that after you have the EOLE or coding DTC's; that if you don't bypass an alarm zone or verify all the zones & battery voltage is at least 13.25 Volts at all times under load or you may get blocked in a routine.

The main reason I disconnect ride sensors and lift the car, is to save the pump and not stress out the controller to get it done quick.

If people marked the sensor positions front and back with timing marks, simply readjusting the position you can change height this way too much faster.
In some cases I take the sensor rods off and make them adjustable with a double jam nuts for on the car mechanical connected calibrations for off road track use only!

In this case a good FOD or test path for tweaked cars to obtain the specification.

Don't know about ODIS, but with VCDS, you only need to key security code once (on step #1 of post #1). Everything else is spot on. And I'd put to set suspension on AUTO in bold, especially when your intention is to lower the car, and you left it in 'dynamic'. That's what I did, and had to get the module reflashed by dealer. Mastec tech said programming was corrupted when suspension bottomed out during calibration, aborting the procedure. Nothing can fix that other than reflashing the module. By the way, I'm the one that Jack linked above, and I see he said I'm the example how not to act? He was the one who behaved like a jacka$$ first (judge by yourselves), and I just followed suit. I apologized to Uwe, and asked him to remove the thread, since nobody knew how to fix my issue... plus it couldn't be fixed by VCDS anyway.
