Blocks, VCDS tries to elaborate as much as possible what the data means.
Unfortunately, the "Data Type" information coming from the Control Module is
not that precise. For example: VCDS can tell that a particular field contains a
Temperature, but the data from the Controller doesn't tell us whether this
is the Coolant Temperature or the Intake Air Temperature.
To reduce the confusion, VCDS supports Label Files which provide more
information about the data being displayed in Measuring Blocks and can also
provide additional information for the Coding function and Adaptation
Channels. When a Label file for the Control Module you
are looking at does not exist, VCDS will base the elaboration is based on an "educated
guess" what a particular Data Type means.
When accessing a control module, VCDS will first search for label files in the following folders in this order:
In each of these folders, VCDS will
search for a Label Files in the following order:
where NN is the controller address (01 for Engine, 03 for ABS, etc)
XXX-XXX-XXX-XX.LBL where XXX-XXX-XXX-XX is
the complete part number for the controller,
including suffix letters
XXX-XXX-XXX.LBL where XXX-XXX-XXX is the
part number for that controller without
any suffix letters.
AA-BB.LBL where AA is the first two
characters of the part number, and BB is the address.
In the last two cases, VCDS may make use of
Label File Redirection.
We have created a TEMPLATE.LBL file that explains and demonstrates the
file-format. This is located in your VAG-COM/Labels folder. If you rename it
to TEST-01.LBL, it will display when you use the Measuring Blocks function
on your Engine. Please do this if you have any questions about the file
We do not have enough resources to create LBL files
for every control module ever made, nor do we have all the control modules
to test them on, so we are asking the user community to get involved:
Please go through each control module in
your car. Go to Measuring Blocks
first. Look in the upper left-hand corner of the screen to see if VCDS
has found a label file. If it says "none", make a note of this control
module's exact VAG Part Number (as shown on the
Open Controller screen.
If no label file exists, we may be able to suggest one that's close for you
to test and tweak, or we may be able to help you find the info necessary to
make a label file. If a label file already exists, go through
all the Groups of data to see if the labels in the file are complete and
make sense. Don't forget Coding
and Adaptation as well.
If something isn't right or information is incomplete, edit the file!
Please send all new or improved label files to
for instructions on
When you download and install VCDS, it creates the VCDS/Labels
directory and populates it with all current Label Files.
