General

The oil level is constantly monitored by the oil sensor, and the

appropriate data transmitted to the processor by the ASSYST.

Oil replenishments are detected automatically and result in a bonus,

which extends the service interval accordingly.

An excess oil level or insufficient oil level appears in the display

together with the oil can symbol.

Display of low oil level at maximum:
D
at driver request

Display of warnings: D
automatically, at the earliest 60 s after engine start and oil

temperature greater than 60°C:

D
if oil level too high: the oil can symbol appears together

with the readout "OIL LEVEL ABOVE MAX". In addition, a

brief warning signal sounds. (On models not fitted with

multifunction displaly, "HI" appears flashing.)

D
if oil level too low: the oil can symbol appears together with

the readout "OIL LEVEL BELOW MIN". In addition, a brief

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on and the

readout "-2L" appears flashing.)

-----------------------------------------------------------------------------------------
D

if oil at minimum: the oil can symbol appears together with

the readout "OIL LEVEL MINIMUM". In addition, a brief

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on.)

D
automatically 13 s after ignition ON:

D
if
no oil
is in engine: the oil can symbol appears together

with the readout "OIL LEVEL BELOW MIN". In addition, a

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on and the

readout "-2L"appears flashing. In addition a brief warning

signal sounds.)

The missing oil quantity displayed no longer changes during the

display. In other words, any change in oil level cannot be observed

directly at the display. The new oil level is only displayed once the

conditions described below exist.

Display of oil quantity at driver request

The text "DISPLAY OIL LEVEL?" appears 10 s after the start switch

has been turned into position "2" (on models not fitted with

multifunction display, the oil can and the clock symbol are displayed).

If the reset button of the trip counter is pressed twice within one sec.

during this readout, for example, "add 1.0L oil" (or "-1.0L")

-----------------------------------------------------------------------------------------

appears in the display if oil level too low. The readout appears only

after the elapse of a waiting time after engine OFF. The waiting time

depends on the engine oil temperature.

It is

D
up to 20°C
30 minutes

D
from 60°C
1 minute

D
The waiting time is between these two limits at other engine oil

temperatures.

Possible readouts are (text in parenthesis relates to models not fitted

with multifunction display.):
D
"OIL LEVEL OKAY" ("o.k."),

D
1.0L, 1.5L, 2L,

D
"Overfilling" ("HI"),

D
"OBSERVE WAITING TIME" (clock symbol flashing and oil can

symbol),

D
"DISPLAY OIL LEVEL" (clock and oil can symbols.)

If there is a fault at the oil sensor (oil level/temperature/quality, B40)

the oil can symbol and the text "OIL LEVEL SENSOR FAULTY"

appears only 30 s after the fault has occurred.

(On models not fitted with multifunction display, the oil level warning

lamp (A1e12) comes on accordingly.)

For diagnosis, read also the injection system control module (N3)

with the HHT. (The instrument cluster (A1) receives the sensor data

through the CAN from the injection system control module (N3)).

-----------------------------------------------------------------------------------------
Oil change

The ASSYST has to be reset each time the oil is changed. Resetting

ASSYST also resets the remaining time and the remaining distance.

Resetting can be performed at the instrument cluster or using the

HHT.

The following data are stored when the system is reset:

D
current kilometer reading rounded off to 100,

D
total oil replenishments in the last interval,

D
remaining distance,

D
remaining time,

D
product of the quality factors,

D
the data of the last 5 resettings in 5 data sets

These data can only be read with the HHT!

If the specified quantity of oil is not replenished when the oil is

changed, the (internal) start distance is reduced.

Detecting oil replenishments
D
With the
HHT
it is possible to retrieve the last 10 oil

replenishments and the corresponding kilometer readings of

the current interval.

D
In the normal case, detection of an oil replenishment is

displayed by the remaining distance in the instrument cluster

being extended

Warning threshold (in days)
With the HHT it is possible to set a warning threshold of between 5 and 30 days for the remaining time, with a
stepwidth of one day. The basic setting is 30 days.
Display of remaining time
The remaining time is always only displayed in those cases where the following condition is met:
Remaining time (in days) x 40 < remaining distance (in km), and the warning threshold is reached.
The remaining time is displayed in the following cases:
automatically, after 5 s start switch in position 2 or driving, if the warning threshold is reached:
The service symbol and the readout "SERVICE IN ... DAYS" appears for 10 seconds. (On vehicles not
fitted with multifunction display, the current remaining time, the service and the clock symbol appear.)
automatically, after 5 s start switch in position 2 or driving, if the remaining time is exceeded:
The service symbol and the readout "DAYS ... EXCEEDED" appears for 30 s (for 10 s up to mid-July
97). (On vehicles not fitted with multifunction display, the service and the clock symbol appear. The
"remaining time" is displayed with a negative sign (minus sign). The readout flashes in this case.)
After the display reaches the maximum readout of -730 days, the readout remains at this figure! The
readout is displayed with a resolution of 1 day.
As of approx. 06.97 a brief warning signal sounds in addition.
at driver request. The readout is then displayed, as above, for 10 s.
If a speed limit is set at the cruise control, this speed limit is displayed for a short moment before the
ASSYST display.
If certain measured values are not supplied to the ASSYST, e.g. because of failure of a sensor, it switches to
stored substitute values. An appropriate entry is then made in the fault memory of the particular control module.
If the power supply fails, the data are retained. The times without operating voltage (battery disconnected) are
not recorded, however! They can be retroactively included, however, with the HHT.

Notes on HHT previous knowledge diagnosis
IC


HHT :

The instrument cluster and active service system (ASSYST) sub-

function are checked with HHT, there being the choice of the

following functions for this:
1. Control module version

2. Fault memory

3. Actual values

4. Actuations

5. Control module adaptation

Additional information on test items 2, 3 and 5 can be called up using

the INPUT key


Control module adaptation

The following alternatives are available in the HHT under control

module adaptation:

1.)
Read out coding and transfer to new instrument cluster. IC and

ASSYST.

2.)
Read out/change codings e.g.:

Engine and national variants,

version of fuel tank,

special equipment etc.
3.)

Settings:

1
Clock

2
Put forward kilometer reading

3
Put back kilometer reading

4
Oil change

5
Reset oil change initiated inadvertently

6
Active Service System

7
Enter times with battery disconnected

8
Set minimum oil warning


Before replacing a defective instrument cluster, readout the existing

variant codings (driving data and instrument cluster data) and store in
the HHT on an interim basis. Read in the values stored on an interim

basis again after installing the new instrument cluster.

If it is not possible to read out the stored variant coding, all variant

codings must be input manually (menu-assistance in HHT).

When installing an instrument cluster on an experimental basis, do

not put forward the kilometer reading as it cannot be put back later.
