Maintenance

BMW Maintenance System

The BMW Maintenance System helps
uphold the road safety and operating
reliability of your BMW. It also makes
provision for comfort and convenience
aspects, such as timely replacement of
the filters for the air inside the car. The
objective is optimisation of the mainte-
nance measures with regard to econ-
omy in total cost of ownership.

When the time comes for you to sell
your BMW, a full service history will be
of advantage.

Service interval indicator

The service interval indicator tells you
when an oil service, an inspection – I or
II, alternately – or a brake fluid change
is due. The system is special in that the
actual conditions under which your
BMW is used are taken into account in
computing the service intervals, instead
of having them based solely on dis-
tance covered.

The technology developed for this pur-
pose takes into consideration your per-
sonal style of driving and the general
conditions in which your BMW oper-
ates. This is because short-distance
driving, which necessarily entails a
large number of cold starts, and moving

away at high engine speeds, impose a
strain on your BMW that is not the same
as that of long journeys with the engine
at a constant operating temperature.

Special note on engine oil
changes

The principle on which the service
interval is calculated covers virtually all
the operating conditions to which the
vehicle is likely to be exposed. How-
ever, if you use your car very infre-
quently, you should have the oil
changed every two years at the latest,
since engine oil ages regardless of the
conditions of operation.
