Instruments - Cluster Recoding After Engine Replacement
911 (996)4/04 1001
Binder 1, Engine - Part 1
Date: 10-22-04
Replacement Engines: Types M96.03 and M96.03 S (X51)
Vehicle Type:
911 Carrera (996) / 911 Carrera 4 (996)
Model Year:
2002 (2) - 05 (5)
Concerns:
Replacement engine, engine types M96.03 and M96.03 S (X51)
- Modified position of oil level sensor in crankcase
- Incorrect display of oil level in display of on-board computer
Information:
Since September 8, 2004, engines have been produced with a oil sensor positioned lower in the crankcase. In order to prevent an incorrect display of the oil level in the on-board computer display after replacing an engine, the engine number must be checked and the instrument cluster recoded if necessary.
Affected Engines:
Standard replacement, or high output (X51) engines produced as of September 8, 2004 from the following engine numbers:
Tools:
PIWIS Tester with test software, version 5.0/10/2004 (or higher).
Work Procedure:
Engine numbers of the old and replacement engine need to be checked and the instrument cluster recoded if necessary.
1. Read the engine number of the removed engine and the engine number of the replacement engine on the underside of the crankcase (Figure 1, arrow) and make note of it.
Note:
The engine number is required for coding the instrument cluster. Refer to the table for applicable steps.
Caution!
The programming operation must not be interrupted. The electrical system battery must be connected to a suitable battery charger with at least 40 A current rating.
> If there is an interruption due to a voltage drop while programming, malfunctions in the instrument cluster cannot be ruled out
2. Connect charger to the electrical system battery and switch on.
3. Switch on ignition.
4. Connect PIWIS Tester with test software version 5.0/10/2004 (or higher) to the diagnosis connector according to Workshop Manual, Group 0, Diagnosis and read out all fault memories. If one or more faults are stored in the memory, these must be located and eliminated according to OBD manual II.
5. In the menu "Control units", select "Instrument cluster".
6. In the Control units menu "Instrument cluster" under "Coding", change to "Coding instrument cluster" > "Oil level characteristics" by confirming with the [>>] key.
7. Follow the instructions of the diagnosis tester, enter the engine number from the installed engine and confirm with the [F7] key.
8. In the display of the diagnosis tester, the display "Coding new oil sensor position" appears. Carry out coding by confirming with the [F8] key.
9. The instrument cluster and DME are coded and ended with the Tester display: "New oil level characteristics"
10. Return to the start menu.
11. Switch off and disconnect the PIWIS Tester.
12. Switch off the charger and disconnect.
13. Carry out a function check of the instrument cluster.
14. Switch off the ignition.
