If IC increases beyond 1, communications are less than 100% reliable.
Counts transmitter errors within individual packets. TE greater than
0 can indicate unreliable communication.

"Identification" data is presented here.
VAG Number is the VW/Audi part
number for this controller.
Component contains more
identification information about the controller and may contain a
version number for the controller's internal firmware.
Soft. Coding is the Software
Coding that determines various options for the controller.
Shop # identifies the
WorkShopCode stored in the scan-tool that last Recoded this Control
Module. Note: Some older Control Modules are not "codeable" and you may
see a Bosch part number or other information in these fields.
The Extra fields can show VIN

This grouping of "Safe"
functions are used to read various
data from the Control Module. VAG-COM checks which functions are supported
by each control module and enables the buttons for supported functions
only. It is normal for some buttons to be grayed out on some control
modules. This is an indication that the control module in question
doesn't support those functions. You can click on each of the buttons in this on-line Demo for more information on the individual functions.
These functions are capable of making
various "programming" changes to the Control Module. You should refer to
the Factory Repair Manual for your particular car (or to other
documented procedures) before "playing" with these functions. It is
completely possible to render your vehicle inoperable or damage
components if you make changes in this section without the correct
information and training. You can click on each of the buttons in this on-line Demo for more information on the individual functions.
