General information

The instrument cluster contains an electronic speedometer, tachometer, liquid crystal (LCD) displays for odometer, trip odometer, digital clock with date, as well as analog coolant temperature and fuel level gauges. Control and warning lamps are situated within the speedometer and tachometer faces.

A "Driver's Information System " LCD is located between the tachometer and speedometer. Displayed information includes an auto check system, outside air temperature, radio frequency and selectable trip computer functions.

The auto check system integrated with the Driver's Information System monitors the brake system, coolant temperature, fuel level, engine oil pressure, and displays the ambient temperature as a default.

The optional Navigation system display is also included in the Driver's Information System (where applicable).

The instrument cluster is controlled by a microprocessor and has extensive On Board Diagnostic (OBD) capability. If malfunctions occur in any of the system components, corresponding DTCs are stored in the Diagnostic Trouble Code (DTC) memory of the instrument cluster. DTCs are read and identified using VAG 1551 Scan Tool (ST), VAG 1552.Mobile Scan Tool (ST), VAS 5051 Vehicle Diagnostic Testing and Information System or VAS 5052 Vehicle Diagnostic and Service System in mode "Guided Fault Finding".

NOTE: The descriptions and displays in this section refer only to VAG 1551.

The following adaptation (adjustment) functions are also possible:

Adapting fuel gauge sender resistance range
Adapting fuel consumption display
Coding of language versions for on-board computer and Auto Check system
Resetting service interval display
Setting distance/kilometer counter after replacing instrument cluster

Message "dEF" on trip recorder display

If the control module in the instrument cluster detects a malfunction in its permanent memory, the letters "dEF" will appear on the trip recorder display.

If "dEF" appears on the display, replace the instrument cluster. Refer to Instrument cluster, removing and installing .

Notes on replacing instrument cluster

The instrument cluster must not be disassembled.
If necessary, the instrument cluster can be replaced with an exchange unit (where applicable).
Complete the damage report form and return it together with the malfunctioning instrument cluster.
Malfunctioning units must always be returned in their original packing.
