WNK6 - Replacing Spreader Device (Actuator) (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:
As of 2021 up to 2022
Model Line:
911 (992)
Equipment:
Porsche Doppelkupplung PDK (M-No. 250)
Concerns:
Spreader device (actuator)
Cause:
There is a possibility that the spreader device (actuator) for the electric parking brake (EPB)
does not meet the required specifications on the affected vehicles.
If this is the case, cup springs, over a long service life, can potentially break in the spreader device and
this can result in function restrictions when the electric parking brake is actuated.
Action required: •
