The Adaptation function allows you to alter
certain values and/or settings in control modules which support it.
Warning:
You should refer to the Factory Repair Manual for your particular car (or some
other documented procedure) before "playing" with the Adaptation function.
However, many available Adaptation Channels are totally undocumented!
You can use the
[Up] and
[Dn] buttons next to Channel
Number to scroll through all 99 possible channels, or you can manually enter
a channel number and click [Read].
If a channel exists, VAG-COM will show you the Stored Value. If a
channel does not exist, the Stored Value will show as "N/A". Other data the
controller may or may not send will be decoded and shown in the four display
fields at the top of the screen.
Once you have reached a channel of interest,
you can use the [Up] and
[Dn] buttons next to New Value
to incrementally change and test the value. Or you can directly enter a New Value
and click [Test]. This will
tell the controller to temporarily use the new value so you can evaluate it's
effects.
When you are satisfied with the effect of a
New Value, you can store it in the Controller permanently by clicking
[Save].
Notes:
-
Channel 00 is a special case.
Performing a [Save] to Channel 00
resets all adaptation values to their original factory defaults. This only works
in controllers that support this function, see your
Factory Repair Manual to find out if
this procedure applies to each controller in your vehicle.
-
Some Engine and Immobilizer
controllers will require a valid Log-In before
permitting you to [Test] or
[Save] Adaptation values.
-
Values put in with [Test] but not
Saved will persist until controller is powered-down.
Click
[Done, Go Back] to return to the Open Controller Function Screen.
Long Adaptations. Used/needed (for
example) to balance the fuel injectors on Common-Rail TDI engines such as the
BKN.
As of version 404.0, Label Files can support values and description for Adaptation
channels. This help chart is displayed in a balloon:
