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.
