MCS system
The radio and navigation unit (A2/56) is the central component of the MCS system . It has a video-capable 5"
active matrix TFT display for indicating information such as control menus and map data for navigation.
Actuation is accomplished in operating modes NTSC (US standard) PAL (ECE standard). It is operated with
fixed function keys and a rotary knob, a joystick as well as with menu-guidance on the display.
The basic version of the radio and navigation unit (A2/56) is equipped with
a radio reception unit,
a compact cassette player and
a speed-dependent volume control.
Diagnostic interface
To read out actual values and DTC's of the MCS and components connected via the digital data bus ( D2B )
diagnosis with the hand-held tester is possible via a K-line.

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.
