WMG6 - Retrofitting Control Unit for Acoustic Simulator (Workshop Campaign)
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 Year:
2021
Model Line:
Taycan (Y1A/Y1B)
Concerns:
Control unit for acoustic simulator (i-Sound)
Information:
Due to worldwide semiconductor shortages experienced by some suppliers, the affected
vehicles were built without an acoustic simulator control unit.
As a result, sound enrichment in the passenger compartment is not available on these vehicles.
Action required: Retrofit control unit for acoustic simulator.
Affected
Vehicles:
Only vehicles assigned to the campaign (see also PCSS Vehicle Information).

Retrofitting Control unit for acoustic simulator
Information
The affected acoustic simulator control unit for interior sound is located at the rear right. The acoustic
simulator control unit for the exterior sound is located at the rear left and is not relevant for this
campaign.
Please note therefore that the relevant components on the right-hand side of the vehicle must be
removed in order to access the installation position of the affected control unit.

Risk of irreparable damage to control unit
•
Risk of damage to control unit
•
Fault entries in the control unit
•
Coding in the control unit is aborted
•
Malfunctions in control unit, even during programming

Before disconnecting the control unit, switch off ignition and remove ignition key.

Make sure that the power supply is not interrupted during programming.

Connect battery charger/power supply - Suitable for AGM Type batteries, recommended current
rating of 90A fixed voltage 13.5V to 14.5V.
Information
Ensure the consistency of a combination of hardware and software versions
After performing software updates, always make sure that the target software versions are also
actually installed on the control units and that the system is therefore ensured.
This also applies in the case of hardware replacement.
See TI 9X00 Information on the software system for various control units in the vehicle (112/21)
