Removing And Installing Instrument Cluster
Removing instrument cluster
INFORMATION: If the vehicle is equipped with a handsfree telephone, disconnect the microphone plug connection instead of the dummy plug.
1. Disconnect the battery and cover terminal or battery.
2. Switch on the hazard warning light switch (button comes out).
On the sides of the button, there are small openings that project beyond the dashboard insert.
3. Insert two small screwdrivers into the openings and pull off the button -A- towards the front.
4. Unclip the collar from the dashboard insert.
The hazard warning light switch -B- is held in the dashboard insert by two locking hooks.

Installing instrument cluster
1. Engage electrical plug connections and fasten the dashboard insert on the dashboard.
2. Install hazard warning light switch.
3. Press button -A- onto the hazard warning light switch -B- until the button is heard to engage.
4. Connect the battery and perform a function test.
If a new instrument cluster has been installed, it must be coded.
Coding the instrument cluster
INFORMATION:
- As of model year '02, the tolerance of the speed display has been restricted. This was achieved by changing the software ("K-number") on the instrument cluster and PCM control module. The "K-number" varies depending on vehicle type and country equipment.
- The reason is as follows: different displays of the total mileage and the fuel consumption/average consumption in the instrument cluster and the PCM control module.
- Therefore, in the case of repairs, the K-number in the instrument cluster must be corrected with the Porsche System Tester 2 (PST2) after the installation of a new instrument cluster in vehicles as of model year '02 If this correction is not carried out, conflicting values for the total mileage and fuel consumption/average consumption will be displayed on the instrument cluster and the PCM control module when in driving mode.
PROCEDURE for coding the instrument cluster:
1. Connect the PST2 to the diagnostic socket; switch on the PST2 and the ignition.
2. In the menu "Control units", select Instrument cluster
3. In the function selection, select Coding.
4. Select menu item Country coding.
5. Select the respective country and code with F8 key.
The other menu items are described in the Diagnosis Manual.
INFORMATION: In general, the K-number is adjusted when coding the instrument cluster. However, this point must be checked again when coding is complete, as described under PROCEDURE for changing the "K-number" in the instrument cluster (as of PST2 software 13.0):
PROCEDURE for changing the "K-number" in the instrument cluster (as of PST2 software 13.0):
6. In the function selection, select Synchronise K-number.
7. Start the function using the key {>>}.
8. After the function has been successfully performed in the instrument cluster, the message K-number synchronised or the message K-number updated appears in the Tester display. If the K-number is not updated, a connection to the PCM is set up automatically. The message Connecting to PCM appears.
9. Then the message Function successfully completed appears.
10. Return to the Start menu with the button ESC, switch off the PST2 and disconnect from the diagnostic socket.
