Instrument cluster with long
service life, On Board
Diagnostic (OBD) (from m.y.
2000)

General information


Technical features of the instrument cluster
The instrument cluster is equipped with a service
display which can process flexible data, that is,
the instrument cluster evaluates various vehicle
based service requirements on input quantities
such as driveability or oil consumption.
The long service life is capable of reproducing
the functions of the standard SRI, when the limits
are set correctly. The limits are variable (in U.S.
with set limits Table Page 01
-80
).
It is also possible to evaluate the oil temperature
sensor. Adaptation channels in the VAG On
Board Diagnostic (OBD) make this possible.
