Models Affected: 911 Carrera 2/4 Model years '89 (K), '90 (L) and'91 (M)


Concern: Ignition cables from the ignition coils to the ignition distributors may chafe on left engine lid hinge ground strap.








Vehicle Information: Routing of the ground strap on the left engine lid hinge was changed in production as of April 15, 1991 (Figures 1 and 2).

From VIN: 96 - MS 41 1509 - Coupe
96 - MS 44 0726 - Targa
96 - MS 46 2089 - Cabriolet


General Information: The ground strap on the left engine lid hinge could contact the ignition wires on vehicles prior to the above VIN'S. This could lead to chafing on the ignition wires and/or warning symbols lighting up (usually ABS and central warning).

Repair Information: The routing of the ground strap should be checked and, if necessary, changed when the vehicle is in the workshop for normal service or other repairs.

Work Procedure: Loosen ground strap on body.





Route ground strap towards outside of engine lid hinge lower part (Figure 3).

Tighten ground strap on body. Strap mounting terminal should point forward with strap looped to the rear.

Minimum clearance between ignition wires and ground strap should be 15 mm with engine lid closed.

Replace chafed ignition wires where necessary.


Note: The function of the ignition circuits 1 and 2 must be checked every time the ignition wires are pulled off during repair and maintenance work. Refer to 911 Carrera 2/4 Workshop Manual, Volume 1, page D24/28-27.
