Instrument panel, On Board Diagnostic (OBD) (through MY 1999) (Page 01-1)
Notes:
The instrument panel is installed in conjunction with vehicle equipment level, there are different
versions:
Lowline version with rev counter and digital clock or
Midline version with rev counter and multi-function indicator or
Highline version with rev counter, multi-function indicator and navigation display unit.
Notes when exchanging instrument panels
Instrument panels which do not have the function "Convenience anti-theft system" have a control
unit part number where the last number is a 0 (production to approx. 07.98).
Instrument panels which do have the function "Convenience anti-theft system" have a control unit
part number where the last number is a 1 (production from approx. 08.98).
If a instrument panel with the function "Convenience anti-theft system" is replaced, then for
vehicles with
Radio system Premium IV 05.98
the radio electronic anti-theft system must be reactivated.

The instrument panel must not be dismantled.
If required the instrument panel is to be exchanged using normal exchange part
procedures.
Complete damage report form and return together with instrument panel.
Use original packaging only when returning items.
The odometer reading and the service interval display can be matched to the
exchange instrument panel using scan tool VAG 1551 Page 01-48.
The instrument panel is controlled via a microprocessor which is equipped with an extensive selfÂdiagnosis.
If faults occur in the sensors and components being monitored, they will be stored in the fault
memory together with an indication of the type of fault.

A maximum of 4 faults can be stored simultaneously.
Sporadic faults are automatically cancelled if they are not repeated in next 50 engine starts.
The On Board Diagnostic must be initiated at the commencement of fault finding and the stored
information interrogated with the
Vehicle Diagnosis, Testing and Information system VAS 5051 or
Scan tool VAG 1551 or
Vehicle system tester VAG 1552.
