WLD3 - Replace Engine Mounts and Retrofit Caps (Workshop Campaign)

Model Line:

911 (992)

Model Year:

2020

Equipment:

Dynamic engine mounts (PADM) (I-no. JQ3)

Subject:

Engine mount

Information:

There is a possibility that moisture can get into the dynamic engine mounts (PADM) on the
affected vehicles as a result of spray water while driving on wet roads, for example, due to an
inadequate seal.
This can cause an electrical fault in the control system for the dynamic engine mounts. If this happens,
the engine mount will act like a conventional mount and a corresponding warning message will be
displayed in the instrument cluster.

Remedial
Action:

•
•

Replace dynamic engine mounts with engine mounts with an optimized seal
Retrofit additional caps on the engine mounts

Affected
Vehicles:

Only vehicles assigned to the campaign (see also PCSS Vehicle Information). This campaign affects
1018 vehicles in North America.
