Concern:
Manual rear spoiler operation modified.

General Information:
A new version rear spoiler control unit, Part Number 964 618 212 00, is installed from production date February 1992. With the introduction of the new control unit, the manual operation of the rear spoiler at road speeds between 0 and 50 mph changed as follows:

- At road speeds between 10 and 50 mph, brief actuation of the spoiler switch in the center console activates the spoiler.

- At road speeds below approximately 10 mph, the spoiler switch needs to remain activated until the spoiler reaches the desired position.

- When decelerating from speeds above 50 mph, the spoiler can be operated manually at speeds between 50 and 0 mph.

Service Information:
- New version control unit can be installed in all 911 Carrera 2/4 models prior to the above production date.

- Model year 1989 (K) and 1990 (L) vehicles still need the additional control unit located under the right seat.

- Manual activation of the spoiler on 1989 (K) model cars is only possible with the service switch under the engine lid.
