Working with vehicle diagnostic testers
• Only work with vehicle diagnostic testers from Volkswagen.
Various functions are available in the operating modes
Guided
functions
and
Guided fault finding
. The 3 most important
functions are:
♦ Adapting installation information
♦ Reading measured values for mandatory reporting
♦ Initiating basic adjustment
Adapting installation information
The mechatronic unit detects other control units in the vehicle by
means of signals on the data bus. Pressing the
Adapt instal-
lation information
button instructs the mechatronic unit to
forget all communication partners.
All »active partners« are detected once again the next time the
ignition system is switched on.
You cannot »generate« any faults using this function. Please al‐
ways perform the
Adapt installation information
function
after the following activities:
♦ Following installation of a gear selector mechanism.
♦ After another control unit has been installed, e.g. engine, ABS
or gateway.
♦ After work on the steering wheel paddle.
Reading measured values for mandatory reporting
You must read these measured values before contacting your
Technical Service Center or your importer.
Save the measured values in the diagnosis log so that all neces‐
sary gearbox data will be available for fault analysis.
Initiating basic adjustment
This teaches important settings into the mechatronic unit. Even
important adjustments are taught in again, or reset to program‐
med points. These include, for example, the synchronisation
points and »reference points« for the engaging lever and gear
actuator.
WARNING
Do not carry out basic adjustment without a reason unless re‐
quested to do so!

♦ after you have installed a dual clutch
