VCDS - Login - Section 15-A
(VAG 1551/1552 function 11)
The Login Function must be used on some (but not all) Control Modules before you can
Recode or change Adaptation values. On others, it "enables" certain features like cruise
control. Valid Login codes can be found in the Factory Repair Manual for your car.
If you are working on an Immobilizer, select [Use 7-digit PIN/SKC] to enter a 7-digit Secret
Key Code. This function is described in Section 16.
Balloons: VCDS can show Login "charts" when appropriate information is available in a
Label File for the control module in question. The balloon will appear after a few seconds if
the Label File contains the appropriate information.
This warning appears in the upper
right corner of the screen if a
session is disconnected after you
have done a Login. ►
The most common cause of this is the use of an incorrect login code or a 7-digit PIN/SKC
based on an incorrect Immobilizer ID or incorrect data entered in the 7-digit dialog. You will
need to exit the Controller and do another Login. In some cases the module may “timeout”
for exponentially increasing durations with each invalid Login attempt.
Use the [Do It!] button to save the Login and return to the Select Function Screen.
Use the [Cancel] button to cancel the Login and return to the Select Function Screen.
