odometer AUDI A4 1999 B5 / 1.G Instrument Cluster OBD From Model Year 1999 Workshop Manual

01-2
The speedometer contains a LCD display for the
odometer, a trip odometer and the Service
Reminder Indicator (SRI).
Indicator lamps are integrated in the
speedometer and tachometer.
Accessory instruments are integrated into the
instrument cluster.
The instrument cluster is controlled by a
microprocessor and has extensive On Board
Diagnostic (OBD) capabilities. If any component
exhibit signs of failure, a Diagnostic Trouble
Code (DTC) is stored in the instrument cluster
DTC memory. The DTC can then be identified
using the VAG1551 or VAG1552 Scan Tool
(ST).

Instrument cluster replacement notes

Do not disassemble the instrument cluster.
All warning and indicator bulbs can be replaced
separately: m.y. 1997 Page 90
-4 ; 1998
Page 90
-15
. All other malfunctions require
replacing the complete instrument cluster.

If necessary, the instrument cluster should be
exchanged within the parts exchange program.
Fill in the Failure Description Form and send it
in, together with the instrument cluster.
The instrument cluster must be sent back in its
original packaging.
When replacing the instrument cluster, set the
Odometer display and the Service Reminder
Indicator (SRI) using the VAG1551 Scan Tool
(ST) Page 01
