Cause
Remedy

Refuel recognition software may not

recognize incremental refueling (< 7 L).

In case of complaint
#

The fuel gauge operation defaults to back-

up mode, and continuously decreases last

stored sensor value based on consumption

data supplied via engine management. This

continues until either refuel recognition or

instrument cluster (A1) reset occurs (via

STAR Diagnosis or power disconnect).
Vehicles with 83 L fuel tank (as of MY2002)
are more susceptible to this condition.

This applies only to instrument clusters

(A1) with diagnostic version 3/05, 3/06,

and 3/07.
1
Connect STAR Diagnosis.

2
Under "Control module adaptations" in

"ICM" menu, set "Fuel tank characteristic

curve" from "Normal" to "Direct sensor

value".

DO NOT replace the instrument cluster

(A1) or fuel pump assembly (M3) for this

condition.
