WNK5 - Exchanging 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 Series:
718 (982)
Equipment:
Manual transmission (M-No. 480)
Concerns:
Spreader device (actuator)
Information:
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 can potentially break in the spreader device over a longer service life, and
this can result in function restrictions when the electric parking brake is actuated.
Action required: •
•
Scope 1 and 2: Exchanging left spreader device (actuator)
Scope 3 and 4: Exchanging left and right spreader devices (actuator)
Information
Every vehicle is assigned exactly one campaign scope.
To learn which scope is assigned to the vehicle, see PCSS Vehicle Information.
Affected
Vehicles:
Only vehicles assigned to the campaign (see also PCSS Vehicle Information).
Required parts and materials
Information
Please note that the installation position (left / right) of the spreader device can vary between the
model series.
