Is there a standard to this number? The tires would be part of the distance, so your tire size would be involved.

From a previous post of mine:
"I find it easiest to measure the distance from the top edge of the wheel rim to the upper edge of the fender arc. To this number I add one half the diameter of the wheel rim.

In my case with the allroad's double spoke wheels, the rim diameter is 470mm. Half that is 235mm. So the distance from the top edge of the wheel rim to the fender edge should be 167mm to get the standard 402mm setting. (IN LEVEL 2)

I place the end of my tape measure on the top edge of the wheel rim and note the distance to the highest point on the fender arch edge. For example, if the distance from the wheel rim to the fender is 160 mm, I add that number to the radius of the wheel rim (235 mm) and get a height of 395 mm. It is the 395 mm which would be programmed in the "402 Mod" to get the car back to the standard specs."

No standard. Variations in tire diameter would go into the ground to fender dimension (at 1/2 the variation). ditto over or under inflation. But both a minor (unless someone is running the totally wrong tire sizes on the Allroad). Nominal tire diameter is around 680mm (very small variation between different brands/models for obvious (legal) reasons) for a 225/55x17 standard tire. So all with stock size tires and correct inflation will show more less the same GTF clearance. I just don't use '402' (center of wheel too much trouble to 'find'). Either GTF or 'wheel edge to fender' as you suggested. Both MUCH simpler.

much more user-friendly than that confusing recipe in the Bentley manual. I might just have to get me a VAG-COM tool.

Btw, I have now tested rear shock tuning options and made a DIY about it: https://www.audiworld.com/forums/aud.../#post24682121

I will tune the language with a native soon - by then I hope you understand it. Ask if not.

Disclaimer: I assume no liability or responsibility for any damages or loss that may arise either directly or indirectly as a result of the application of the information provided herein. Please read instructions fully before attempting this modification. Serious harm or injury may come to you or your vehicle by performing these modifications. This mod will seriously alter the handling characteristics of your vehicle. Perform this modification AT YOUR OWN RISK.

What will you need?
A VAG-COM tool:software and cable available from Ross-Tech
A ruler or tape measure if you're looking for precise measurements
And of course, an Audi allroad

What does this modification do?
The Audi allroad comes with a height adjustable suspension that lowers or raises the car through four preset levels. The car's computer includes a calibration tool that allows you to reset the height to factory specifications in case you're car was to get out of normal operating range. This modification "tricks" your car into thinking that it is out of normal specifications. By telling the allroad that it is indeed higher than it really is, it will adjust itself to ride lower on all four settings or vice versa if you were to tell it that it was lower than it really is.

Does the car still go "up and down"?,
Yes. However, if you lower your car 1/2 inch, ALL settings will be 1/2 inch lower. There is NO way to only lower the lowest setting.

How do I alter the ride height of my allroad?

With your engine not running, but the car's ignition set to "on", log into the allroad using your VAG-COM tool. Select "Less Common Modules" you'll see the following screen:




Click on Module 34 to enter the Level Control module. Your VAG-COM will open the module and you'll be presented with this screen. Click on Advanced Function 11 for the Login screen. This function unlocks the adaptation module.




When the Login screen appears, enter in 31564 and click on "Do It". You will then return to the previous screen. Click on module 10 to open the adaptation screen.



When the adaptation screen appears, be warned that you MUST finish the entire adaptation or else you will cause an error and you suspension will be locked in Level 2 until you successfully complete the full adaptation process. If you just purchased your VAG-COM tool and it is still running in "Shareware" mode, you will not be able to complete the process. If you do encounter an error while doing the adaptation, don't panic. Simply start the process over again from the start and it will complete eventually.



Press the UP button next to Channel Number to increase it from the default value of "00" to "01". If required, press the READ button. Your car will automatically adjust it's ride height to Level 2 for calibration. Wait for this height adjustment to complete. Your VAG-COM will list four green N/A's in the top four windows and to stored value will read "402".

Channels 01-04 correspond to the four corners of your vehicle. You must complete the following steps for all four corners of your car.
01 = Left Front
02 = Right Front
03 = Left Rear
04 = Right Rear



"402" is what the allroad ALWAYS thinks is the proper setting for Level 2. The value of "402" according to the Bentley CD manual is the distance measured from the center of the wheel to the bottom of the fender in millimeters. If this is the first time you are performing this modification, and your car has been operating properly, it should be safe to assume that "402" is the proper value. You can also take a tape measure and measure this value if you care to. We will discuss secondary adjustments performed after modifying the ride height later in this document.

Knowing that the allroad at this point "thinks" it's at a 402mm setting, if we were to enter "402" in to the New Value window, we'd be making no change to the ride height. If fact, you can enter in 402 to successfully complete the adaptation process so your car doesn't go into Suspension Limp Mode. Note that although it already reads 402, you will need to delete and re-enter 402 to have to option of testing and saving the settings.

However, if you care to alter the ride height of your vehicle, we must trick the allroad into thinking that it is higher or lower than it really is. Therefore, if we want to lower the allroad 15mm, we would tell the computer that the allroad measured "417" and enter that into the New Value field. To raise the allroad 15mm, we would enter in "387". What you enter is up to you, however, there are some limits as to what the computer will take as a valid entry, so it wouldn't be a bad idea to take baby steps in changing the settings.

To change the setting, enter in the New Value and press the Test button. Once the value is accepted by VAG-COM, press the Save button.



When presented with the "Are you SURE" prompt, click on Yes to proceed.

Press the UP button next to Channel Number again and the value will increase from "01" to "02". Enter in the same number as you did in the previous section into the New Value field and repeat the procedure. Do this until you have successfully set New Values for Channels 01 - 04.

NOTE: You may wish to enter in a slightly different value for Channels 03 and 04 when lowering your vehicle if you prefer for your car to have a more aggressive appearance. 5mm seems to be enough of a difference to prevent the allroad from looking "weighted down" in the rear.

After the four channels have been set to your preference, you must save your settings. After setting and saving Channel 04, press the UP button once more so that the Channel Number reads "05". This channel is for saving your previous work.



Enter in a New Value of "01", test and save. You'll get an error, but don't worry, everything is okay. Click on the "Done, Go Back" button to exit out of the adaptation screen. That's it, you're finished!

For good measure, start your allroad's engine and move up and down through the four levels of your car a few times before going for your first test drive. Once you've confirmed that all works well, carefully go for a test drive to check to see if it is to your liking.

If you need to readjust your allroad after completing your first adaptation, it is important to remember that your allroad thinks the last adaptation set it properly to 402mm between the center of your wheel to the fender. It has no clue as to where it really is set to. Therefore, if you lowered your allroad by 15mm by entering 417 into the New Value field on all four channels and wish to lower it an additional 5mm, you DO NOT enter in 422 the second time around. This will lower your allroad an ADDITIONAL 20mm. Rather, simply enter in 407 and you car will lower itself another 5mm since it thinks it's only off by 5mm. Keep a record of your modifications so you know exactly what number needs to be entered to get your car back to stock settings. Or you can measure and use this adaptation program as it was meant to be used to get your car back to factory specifications.

17mm in the front and 13mm in the rear will make your car noticeably lower, and you probably shouldn't go any lower. As for height, 20mm was accepted by the vehicle, however, no driving was done at this level, so please excercise caution and common sense. And remember the disclaimer above!!!

Great write up.

I'm currently looking into selling my B6 A4 Avant Sport in favour of a an A6 Allroad 2.7TT. I will be needing the convenience of the adjustable height, but still want the lowered ride height for looking good on the normal roads.
The fact I won't have to spend £2k to add aftermarket air ride, and I just have to alter a few settings in vcds has just helped me make my mind up about selling the A4.

Default Automatic suspension adjustment

[QUOTE = vtraudt; 24375143] Eu perguntei em vários lugares (desative a altura automática do dependend), mas não uma resposta (idem Rosstech Vagcom fórum).

Eu penso em colocar um interruptor dentro sugestões para o fio correto? [

QUOTE = danzero; 24375133] Eu sei que esta pergunta foi feita antes, mas eu procurei longe e sem resposta concreta.

Enquanto a maioria das pessoas fazendo o mod 402 parece estar olhando para diminuir seu passeio para o desempenho esportivo (ou para o visual), eu quero aumentar um pouco com o mod 402, e eu gostaria de ser capaz de mantê-lo ocasionalmente levantada quando A minha pergunta é:

existe alguma maneira através do vag-com de alterar (ou desactivar) as definições que baixam automaticamente a suspensão com base na velocidade? Estou ciente de que uma maior altura de direção impactará negativamente o manuseio em alta velocidade (é por isso que a Audi adicionou esse recurso automático de altura). Milhões de SUVs são muito altos, então por que o allroad não pode ser ultrapassado? Eu quero ser capaz de atravessar a neve, ou navegar por uma estrada de terra a uma velocidade maior.

Por favor, diga-me que há uma maneira de substituir esse "recurso".

Obrigado!
DanZero [/ CITAÇÕES]


Hello, I know this has been a long time, but even with many searches, I do not find anything in any other forum ...

Does anyone know of any way to disable the automatic suspension adjustment mode ??

I hope so, hehe

Thank you very much.

Look at the first item Nebuchadnezzar has in his list of items required. You need the Ross Tech system or an OEM dealer tool.
