Inaccurate Fuel Gauge Before Refueling Vehicle
If you receive customer reports in the above model vehicles of the fuel gauge dropping to minimum too quickly and the customer can only add a small
amount of fuel after the fuel reserve indicator" in the instrument cluster illuminates, this may be due to a software error in the instrument cluster. To
resolve follow the steps below.
1.
Install new instrument cluster per WIS document AR54.30-P-6015GH.
2.
Carry out "Pointer Actuations" by using WIN/HHT (Star Diagnosis).
Instrument Control Module --> 4. Activations --> 2. Analog Instruments --> Click "on"
Also for vehicles up to VIN A145274 (up to MY2000) with automatic transmission, perform the following:
1.
Set Transmission Range Indicator to "not active"
Instrument Control Module --> 5. Control Module Adaptations --> 2. Read out / Change code --> 11. Transm. Range Indicator
2.
Set CAN matrix to "ID 310"
Instrument Control Module --> 5. Control Module Adaptations --> 2. Read out / Change code --> 22. CAN-Matrix
Note:
Exchanging the fuel level sensor does not resolve the inaccurate fuel gauge.
