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.

such as the USA, the following constant
adaptation values must be entered:

Adaptation (scan tool function 10)

Individual functions are called up by entering the
appropriate adaptation channel numbers (listed
in the adaptation table Page 01
-134
).

Notes:

Using measuring value blocks 10, 11, 12 and
15, the values that need to be transferred to the
new instrument cluster can be read out before
replacement.
Adaptation channels 42, 43, and 44 (see
measuring value blocks 013 and 014 Page 01
-125
and Page 01
-126
) must be adapted
according to the oil quality (measuring value
block 15 Page 01
-127
).

Adaptation channels 60, 61, and 62 are only
needed when the instrument cluster
communicates with the corresponding BUS
system..
Measuring value blocks 125 and 126 Page 01
-129
and Page 01
-130
indicate the
components that are part of the powertrain
data-BUS.
