WKJ5 - Replacing Generator (Workshop Campaign)
Vehicle type:
718 Boxster (982) / 718 Boxster T (982)
718 Cayman (982) / 718 Cayman T (982)
Model Year:
As of 2019 up to 2020
Subject:
Generator
Information:
Due to a logistical error, the generators for various vehicle types of the 718 (982) and 911
(991) model line were interchanged.
The generators installed in the affected vehicle types with flat-four and flat-six engines are identical,
however the generators differ in the size of the pulley. Consequently, interchanging the generators
results in the nominal speed range of the relevant generator being exceeded or undershot. As a result,
the battery may not charge sufficiently or the generator may become damaged.
Remedial
Action:
Replace the generator.
Affected
Vehicles:
Only vehicles assigned to the campaign (see also PCSS Vehicle Information). This campaign affects 41
vehicles in North America.
