mid-2000 models BMW introduced new
service interval software which
calculates service based on the
amount of fuel used. When SII detects
total fuel consumption that equals the
preset limits (in gallons), the
instrument cluster indicates that service
is required.
Using a 328i as an example:
Standard transmission model: SII
illuminates after consumption of
601 gallons of fuel.
Automatic transmission model: SII
illuminates after consumption of
667 gallons.
After the service is performed the SII
can be reset to zero.
The SII displays the mileage remaining
before service is due. The type of
service (OIL SERVICE or INSPECTION)
is also illuminated in the display.
Note:
An OIL SERVICE interval will always be
followed by an INSPECTION interval,
which will then be followed by an OIL
SERVICE interval, and so on.
When the ignition is turned on, the
service recommendation and miles
remaining are displayed for a few
seconds. A flashing message and a
negative (-) symbol in front of the
number indicate that the service
interval has been exceeded by the
distance displayed.
The On-Board Computer uses the rate
of fuel consumption in the period
immediately preceding to calculate the
mileage before the next service is due.
