service indicator 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).
