INSTRUMENT CLUSTER, ON BOARD DIAGNOSTIC (OBD)
GENERAL INFORMATION
Repair Manual page 01-1.
FEATURES
The Audi A4 instrument cluster includes a "mini-check" system as standard equipment. This system uses a centrally located, multiple warning light indicator array which monitors the brake system, coolant temperature, fuel level and engine oil pressure.
An optional trip computer using a liquid quartz (LCD) multi-function display is also available.
The electronic speedometer contains an LCD display for odometer, trip recorder and service Reminder Indicator (SRI).
Control and warning indicator lights are integrated into the electronic speedometer and tachometer.
Also included are analogue voltmeter, oil temperature, coolant temperature and fuel gauges in addition to an LCD outside temperature display and shift indicator for vehicles with Automatic Transmission.
The instrument cluster is controlled by an internal microprocessor with On Board Diagnostic (OBD) capability. If faults occur on applicable instrument cluster system components, Diagnostic Trouble Codes (DTC) are stored in DTC Memory. Stored faults are identified using VAG 1551 Scan Tool (ST).
