W301-Replacement of Engine Wiring Harness

Vehicle Type:
911 Carrera (993)/911 Carrera 4 (993)

Model Year:
MY 1995 (S) and MY 1996 (T)

Concern:
Engine wiring harness - This bulletin replaces bulletin, Group 9, # 2/01, Dated 10-18-02.

Information:
Porsche is requesting that the engine wiring harness be checked and/or replaced on a certain range of model year 1995 and 1996 911 Carrera (993) and 911 Carrera 4 (993) vehicles.

Based on field information and internal testing, Porsche AG has concluded that the insulation of the wires of the wiring harness may deteriorate. The deterioration of multiple wires may result in shorts which affect the proper function of the engine. Rough engine running, stalling, inability to start the engine due to a dead battery, starter malfunction, and illumination of the Malfunction Indicator Light ("Check Engine" warning lamp) are symptoms for this problem.

The engine wiring harness part number must be checked on all affected vehicles. Depending on what you find when you inspect the vehicle, the wiring harness may then also need to be replaced.

Affected Vehicles:
A total of 10,300 U.S. and 455 Canadian vehicles fall within the scope of this Service Action.

Very Important!
