sequence:
9
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, end operational readiness for
approx. 15 minutes (switch off ignition) and
repeat the procedure described here again.

Then perform software update to software release VR8.7.
3
Start control unit programming of VR8.7.
The basic procedure for control unit programming is described in the Workshop Manual

Information
•
Battery sensor (12-volt vehicle electrical system battery): An actual voltage of at least 14
volts is required for programming the 12-volt battery sensor. Switching the ignition off and on again
after one minute is therefore integrated in the programming sequence. As a result, the voltage of the
12-volt vehicle electrical system battery increases briefly and the programming sequence can be
started. Follow the instructions on the PIWIS Tester.
•
Programming must not be performed if the supply voltage has not yet been checked to be
14 volts. This is displayed on the PIWIS Tester before starting programming.
4
Then perform software update to software release VR12.1.1.
Start control unit programming VR12.1.1 (sequence 2).
