Sequence 3 includes other control units from the software
release VR12.1.1, which are only re-coded.
Following control unit programming, the software version
can be read out of the relevant control unit in the 'Extended
identifications' menu using the PIWIS Tester.

End and restore operational readiness (switch ignition
off and then on again).
Read out and erase the fault memory  Workshop
Manual '9X00IN Basic instructions and procedure for
control unit programming using the PIWIS Tester'.
Repeat control unit programming by entering the
programming code again, whereby extended logging
must be started using the key combination •Ctrl“ +
•L“.
Extended logging records diagnostic software data,
particularly vehicle communication data, which
is required for analysing the issues that caused
programming to be aborted.
If control unit programming is aborted a second time,
stop operational readiness for approx. 15 minutes
(switch off ignition) and repeat the procedure described
here again.

procedure for control unit programming using the PIWIS
Tester - section on "Fault finding"'.
