WMQ3 – Retrofitting Loudspeaker Booster (Stop Delivery)
Revision:
This bulletin replaces bulletin Group 9 215/21 WMQ3, dated May 13, 2022.
Model Year:
As of 2022 up to 2023
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:
Cayenne (9YA/9YB)
Equipment:
Burmester Surround Sound System (M-no. 9VJ)
Concerns:
Loudspeaker booster
Information:
Due to worldwide semiconductor shortages experienced by some suppliers, the affected
vehicles were built without a loudspeaker booster.
Action required: Retrofit loudspeaker booster.
Information
Every vehicle is assigned just one campaign scope.
 To find out which scope is assigned to the relevant vehicle, see PCSS Vehicle Information.
Scope 1: Installing and teaching loudspeaker booster
Scope 2: Not applicable for the US market
Affected
