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

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

Oil replenishments are always only detected once the following

conditions are met:

D
the replenished quantity is
at least 1 l

D
after replenishing the oil, the car must be driven a distance of
at

least 5 km
under
normal driving conditions
at an
oil

temperature of at least 60 °C
.

There are instances, however, in which the readout of the remaining

distance nevertheless appears implausible after replenishing oil;

according to the display, no bonus or only a small bonus has been

issued. This is caused by the fact that the remaining distance is

always only displayed within a range from 15 000 km up to 30 000

km (or 20 000 km up to 40 000 km in the case of engine 668), but

internally the system calculates with the actual values which may also

be beyond this range. These internal values can only be displayed

with the HHT.
In the charts overleaf, a number of examples of this are presented.
The horizontal (x) axis represents the service interval and the vertical

(y) axis is the remaining distance in each case in km.

The readout of ASSYST in the instrument cluster always moves

within the light range.

The remaining distance calculated internally may also, however, be

within the two dark ranges. These internal values can only be

displayed with the HHT.

All examples relate to gasoline engines fitted with an oil sensor.

P00.20-0201-06

Example 1 :

Sufficient oil was added during the oil change.

This means that the starting distance is 15

000 km.

After 10 000 km oil is topped up under normal

driving conditions (a). The bonus (B1) is

issued and displayed. What this means is that

when the remaining distance is retrieved, a

greater remaining distance is displayed.

(Provided the aforementioned conditions for

detecting the oil replenishment are met.)

Oil is topped up again after a further

5 000 km (b). In this case also a bonus (B2) is

issued and displayed.

If, after this, no further oil is topped up and

the car continues to be driven in the same

manner, a service interval of about

24 000 km is thus achieved.

In this example, the curve moves at all points

within the light range of the chart;

consequently, all the oil replenishments are

displayed by increasing the remaining

distance.

P00.20-0204-06

Example 2:

The specified quantity of oil was added when

the oil was changed.

The car is driven under very favorable

conditions and oil is topped up after

10 000 km (a). Internally, the bonus B1 is

issued, the service interval is extended

accordingly by enlarging the remaining

distance. However, as the curve is sometimes

within the shaded area, only the part of B1

which is within the light area, is at first

displayed as an extension of the remaining

distance. (Provided the aforementioned

conditions for detecting oil replenishment are

met.)

Oil is topped up once again at 18 000 km (b).

In view of the fact that the maximum service

interval of 30 000 km was exceeded, the

bonus B2 is not initially displayed as an

extension. The entire service interval in this

case is 30 000 km.

If, from point b, the car continues to be driven

under less favorable conditions, it may still

also be possible now to achieve the maximum

service interval of 30 000 km because of the

internal bonus B2.

d by Modification services.
Page 2

P00.20-0202-06

Example 3:

When the oil was changed, the quantity

added was less than the specified quantity.

Consequently, the start distance is less than

15 000 km.

If oil is now topped up after 5 000 km (a), the

remaining distance displayed is not extended

as the curve is within the shaded area. The

bonus B1 is nevertheless added internally

and results in an extension of the service

interval to slightly more than

15 000 km - provided the driving conditions

remain the same or are more favorable.

(The service interval of 15 000 km is always

reached, however, even if the internal value

were less.)

P00.20-0203-06

Example 4:

Oil has been topped up after 5 000 km under

unfavorable driving conditions (a) and the oil

replenishment (bonus B1) detected internally.

We now have two cases to consider:

D
If the car continues to be driven under

the same conditions (unbroken line), the

remaining distance displayed is not

extended as the curve is within the

shaded area.

The service interval in this case is

nevertheless 15 000 km although the

internal value is less. (The remaining

distance displayed can always only be

within the light area.)

D
If the car continues to be operated

under more favorable conditions

(broken line), the value of the internal

remaining distance slowly moves into

the light area. Consequently, the service

interval may be greater than

15 000 km.
