Model Line:
718 Boxster (982) / 718 Cayman (982)
Model Year:
As of 2017 up to 2022
Concerns:

Information:
There is a possibility that leaves and particles of dirt can get into the side air intakes and accumulate in the air guide under certain environmental conditions.
If the relevant warning in the Driver's Manual is not observed and burning cigarettes or cigars are
also thrown out of the vehicle, this can pose a risk of a smouldering fire developing in the engine
compartment.
Action required: Retrofit or replace protective grilles for the air intakes at the left and right.
Affected
Vehicles:
Only vehicles assigned to the campaign (see also PCSS Vehicle Information).
