Vehicle Type:

Boxster S (981)/Boxster GTS (981)

Model Year:

2015

Concerns:

Underbody protection in rear left wheel housing

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is
a possibility that some of the underbody protection in the rear left wheel housing was not
applied according to specifications on the affected vehicles due to a programming error at a
production station.
As a result, this area can become corroded over the service life of the vehicle.

Action
Required:

Rework underbody protection in the rear left wheel housing and repaint the affected area.
Information
Please inform the customer during vehicle acceptance about the measure that must be carried out.
If necessary, also let the customer know that there can be a smell of paint for a while after the affected
area has been painted.

Affected

The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the
vehicle. This campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper
repair.
This campaign affects only two (2) vehicles in North America:
