Note:

After completion of the automatic
sequence, the instrument cluster
must be briefly disconnected from
voltage supply terminal 30 to allow
the clock correction to take effect.

The clock correction takes effect
after reconnecting the instrument
cluster to voltage supply terminal
30.

The digital clock accuracy is now
corrected.

- Switch off ignition.

- Disconnect VAG 1551 scan tool

from Data Link Connector (DLC).

Instrument cluster m.y.
2000 through m.y. 2001, On
Board Diagnostic (OBD)

General information

The instrument cluster contains an electronic

speedometer, tachometer, liquid crystal
(LCD) displays for odometer, trip
odometer/clock, as well as analog coolant
temperature and fuel level gauges. Control
and warning lamps are situated within and
between the speedometer and tachometer.
Automatic transmission models also contain
an LCD gear indicator display.

Where available, an LCD multi-function trip

computer (MFI) with two operating modes is
located in the tachometer display. The MFI
includes selectable displays for trip
time/mileage, average trip speed, average
trip fuel consumption and outside
temperature.

The instrument cluster is controlled by an

internal microprocessor with On Board
Diagnostic (OBD) capability. If malfunctions
occur in monitored sensors and
components, Diagnostic Trouble Codes
(DTC) will be stored in memory together with
an indication of malfunction type. A
maximum of 4 DTCs can be stored
simultaneously.

Sporadic malfunctions (indicated in the

readout by "SP") are automatically cancelled
if not repeated in the next 50 engine starts.

Instrument clusters from m.y. 2000 are

integrated into the "Powertrain" CAN Data
Bus network (may also be known as "CAN-
Bus" or "Data-Bus").

The Data Bus On Board Diagnostic Interface -

J533- (which is integrated into the instrument
cluster) enables data to be exchanged between
the "Powertrain" CAN Data-Bus network and the
Data Link Connector (DLC) "K-wire".

The Data Bus On Board Diagnostic Interface -

J533- has specific On Board Diagnostic (OBD)
capabilities.

Before performing any troubleshooting or

inspection, always begin by checking for DTCs
using the OBD program. DTCs stored in memory
are retrieved/checked with either the VAG
1551/1552 Scan Tool (ST) or VAS 5051 Vehicle
Diagnostic Tester.

Notes on exchanging instrument cluster

Do not disassemble instrument cluster.

Instrument clusters contain no field serviceable

components. All malfunctions require
replacement of instrument cluster.

When the replacement of a malfunctioning

instrument cluster is necessary, follow
exchange part procedures.

Complete the report form and return together

with instrument cluster.

Use the original packaging from the new cluster

when returning modules.
