Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
During the programming sequence, first the DME
control unit and then the PDK control unit or
transmission control unit, as the case may be,
are re-programmed.
Programming sequence:
Both control units are then automatically
re-coded.
Do not interrupt programming and coding.
Once the control units have been programmed and
coded, you will be prompted to switch the ignition off
and then back on again after a certain waiting time.
Backup documentation of the new software versions
is then performed.
