Service Technical Information 19/20 ENU WLA4 1 WLA4 - Retrofitting Heat Shield (Workshop Campaign) Vehicle Type: 911 Turbo (991) Model Year: As of 2014 up to 2019 Subject: Heat shield on rear cross member Information: In the past, there have been isolated incidences of damage caused by fire occurring in the engine compartment. Analysis of this damage has identified foreign objects or materials (e.g. cleaning cloths) found in the engine compartment as the cause of these incidents. Foreign objects or materials of this kind can touch hot exhaust system components while driving, causing them to ignite. Remedial Action: Retrofit heat shield on rear cross member in the engine compartment. This shield may help to prevent any foreign objects or materials from touching exhaust-carrying or hot components in the engine compartment. Affected Vehicles: Only the vehicles assigned to the campaign (see also PCSS Vehicle Information). This campaign affects 41,925 vehicles in North America.
