Preliminary work
Preliminary work for instrument cluster
Remove top steering-column panel. => 481300 Removing and installing trim panel (steering-column switch) - section on "Removing"
Removing instrument cluster
Installation position
1. If a new instrument cluster is to be installed, read out the values if possible from the instrument cluster. => 902519 Removing and installing instrument cluster - section on "Programming"
2. Loosen the steering wheel adjustment, put the steering wheel in the front-most and lowest position and lock the steering wheel adjustment.
3. Unscrew the two fastening screws -1-.
Unscrewing fastening screws
4. The instrument cluster is also secured in the dashboard with two retaining clips. Therefore, pull the instrument cluster abruptly forward and if necessary push instrument cluster away from dashboard from underneath.
Unlocking the electric connector
5. Release electrical connector on instrument cluster -A- and unplug it.
6. Pull out instrument cluster at the sides and to the left.
Installing instrument cluster
1. Position the instrument cluster, connect the electrical plug and lock.
Connecting electric plug
2. The instrument cluster has two retaining clips; push instrument cluster into the dashboard and press on until the retaining clips engage.
3. Screw down instrument cluster with both fastening screws -1-. => 4.2x16-C: 2.3 Nm (2.0 ftlb.)
4. If a new instrument cluster was installed, => 902519 Removing and installing instrument cluster - section on "Programming"

Reading and printing values
Information
Tank calibration is necessary after replacement of the fuel tank, fuel-level sensor or instrument cluster. Calibrate the fuel-level sensor system - after replacing the instrument cluster - only if the function Read out values cannot be performed.
If the instrument cluster is replaced or exchanged, the instrument cluster must be programmed and coded using the PIWIS Tester 9718. This is done to adapt the instrument cluster to the vehicle and equipment.
If possible, before the instrument cluster is removed and replaced, a read-out of the vehicle data should be obtained using the Porsche System Tester.
During coding, it is essential to guarantee the power supply for the Porsche System Tester. It is essential to connect a battery charger with a current rating of at least 40 A to the vehicle battery.
The Porsche System Tester instructions take precedence and in the event of a discrepancy these are the instructions that must be followed. Deviations may occur with later software versions.
The procedure described here has been structured in general terms; different text or additions may appear in the Porsche System Tester.
1. Connect the Porsche System Tester to the vehicle and start the System Tester. Switch on ignition. >> Continue.
2. Select vehicle type >>.
3. Switch from the vehicle type to the list of control units.
4. Select Instrument cluster and press the >> key.
5. Select Control unit replacement with the cursor keys and press the >> key.
6. Select Read out values (codings) with the cursor keys and press the >> key.
7. The message Coding read-out complete will appear on the screen of the Porsche System Tester >>.
8. Switch off ignition and replace instrument cluster. => 902519 Removing and installing instrument cluster - section on "Removing"
9. Switch on ignition. After replacement of the control unit, the vehicle data is installed under the menu Write in data (see Point 6) > >.
10. System Tester displays Coding write-in complete. Press the >> key.
11. Go to the Special functions menu and start the Vehicle handover also; follow the instructions on the Tester.
12. Erase all fault memories.
13. Go to the Instrument cluster Coding menu again and check the coding in accordance with the vehicle equipment.
14. Carry out a test drive and read out fault memory again.
