WND8 - Re-Programming DME Control Unit (Workshop Campaign)

Revision:

This bulletin replaces bulletin Group 2 72/22 WND8, dated May 27, 2022.

Model Year:

As of 2022

Important:

CRITICAL WARNING -This campaign includes steps where control unit(s) in the vehicle will be
programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5
volts during this programming. Failure to maintain this voltage could result in damaged control unit(s).
Damage caused by inadequate voltage during programming is not a warrantable defect. The technician
must verify the actual vehicle voltage in the PIWIS Tester before starting the campaign and also document
the actual voltage on the repair order.

Model Line:

Macan (95B)

Concerns:

DME control unit

Information:

Due to a possible software error in the DME control unit, there is a possibility that the functionality of catalytic converter heating will be impaired when starting the engine on the
affected vehicles.

Type of control unit programming:

Control unit programming using the 'Automatic
programming' function of the DME control unit:
'DME' control unit – 'Coding/programming' menu
– 'Automatic programming' function.
Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
During the programming sequence, the DME
control unit is re-programmed first, then the PDK
control unit is 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.
