VAG-COM
Adaptation
(VAG 1551/1552 function 10)

The Adaptation function allows you to alter certain 
values and/or settings in control modules which  support it. 

Warning!
You should refer to the Work Shop 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 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.

Note: Channel 00 is a special case.  Performing a 
Save to Channel 00 resets all adaptation values
to their original factory defaults.

Note: Some  Engine and Immobilizer controllers will
 require a valid Log-In before permitting you to Test
 or Save Adaptation values.

Examples of things you can do with Adaptation: 

* Altering the Idle Speed (only SOME engines)

* Changing the Service Intervals and resetting the Service 
Reminder Indicators (newer instrument clusters)

* Disabling/Enabling various components
 of the Airbag/SRS system.

* Changing the sensitivity of the Interior Monitor (Sonar Scan) 
component of the Alarm System in many newer Audis.

* Swapping ECU's and re-matching keys 
(newer immobilizer-equipped cars) 

* Selecting certain Central Locking options in newer vehicles.
