VCDS – Adaptation / Long Adaptation - Section 20-A
(VAG 1551/1552 function 10)
The Adaptation function allows you to alter certain values and/or settings in control
modules that 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 to scroll through all 255 possible channels, or you can
manually enter a channel number and click [Read]. If a channel exists, VCDS 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.
If an uninitialized control module
warning appears, this means that
one or more of the WorkShop Code,
Importer, or Equipment numbers are
all zeros. Since some modules will
not allow you to save Adaptation
values unless non-zero numbers are
in any or all of those fields, VCDS
shows you this error when it thinks
this might be the case. ►
In most cases you should click [Yes] to allow VCDS to enter 12345/123/12345 in those
fields. If you click [No] then VCDS will try using the values currently stored in the module
even if they are all zeros. If you click [Cancel] then VCDS will allow you to manually type in
values for each of those fields.
