MAINTENANCE
PROGRAM
GENERAL
The
information
given
in
this
repair
group
includes
the
routine
checks
and
maintenance
steps
that
are
both
required
by
BMW
under
the
terms
of
the
vehicle
warranty
protection
and
recom-
mended
by
BMW
to
ensure
long
and
reliable
vehicle
operation
.
GENERAL
NOTE-
Aside
from
keeping
yourcar
in
the
bestpossible
condi-
tion,
proper
maintenance
plays
a
role
in
maintaining
full
protection
under
BMWs
new-car
warranty
coverage
.
If
in
doubtabout
the
terms
and
conditions
of
yourcark
warranty,
an
authorized
BMW
dealer
should
be
able
to
explain
them
.
NOTE-
BMW
is
constantly
updating
their
recommended
main-
tenance
procedures
and
requirements
.
The
informa-
tion
contained
here
is
as
accurate
as
possible
at
the
time
of
publication
.
If
hhere
is
any
doubt
aboutwhat
pro-
cedures
apply
to
a
specific
model
or
model
year,
or
what
intervals
should
be
followed,
remember
that
an
authorized
BMW
dealer
has
the
latest
information
on
factory-recommended
maintenance
.
BMW
Service
Indicator
The
BMW
Service
Indicator
notifies
the
driver
when
mainte-
nance
is
required
.
The
service
indicator
consístsof
multiple
light
emitting
diodes
(lEDs)-typically
five
green,
one
yellow,
andone
red-as
well
as
OIL
SERVICE
and
INSPECTION
indi-
cators
.
When
the
ignition
is
tumed
on,the
green
LEDs
come
on
.
They
go
out
when
the
engine
is
started
.
After
the
Service
Indi-
cator
is
reset,
al¡
green
LEDs
will
be
illuminatedwith
the
keyon
.
As
thecar
is
driven
in
normal
use,
fewer
and
fewer
green
LEDs
will
be
illuminated
before
start-up,indicating
that
the
next
main-
tenance
interval
is
approaching
.
When
thecar
has
accumulated
sufficient
use
to
require
the
next
maintenance
interval,
the
yellow
LED
will
come
on
along
with
either
the
OIL
SERVICE
indicator
or
the
INSPECTION
in-
dicator
.
These
LEDs
will
stay
on
after
the
engine
is
started
.
If
maintenance
service
is
delayed,
thered
LED
will
also
illuminate
as
a
reminder
that
maintenance
service
is
overdue
.
An
OIL
SERVICE
interval
will
alwaysbe
followed
by
an
IN-
SPECTION
interval,
which
will
then
be
followed
byan
OIL
SER-VICE
interval,
andsoon
.

BMW
has
taken
a
unique
approach
to
establishing
mainte-
nance
intervals
.
BMW's
Service
Indicator
System
computes
maintenance
intervais
based
not
only
on
elapsed
mileage,
but
Fig
.

.
Service
indicator
display
in
lower
section
of
speedometer
.
also
on
such
inputs
as
enginespeed,engine
temperature,
number
of
starts,
and
length
oftrips
.
At
the
appropriate
time,
the
system
indicates,
through
lights
in
the
instrument
cluster,
when
Oil
Service
the
next
routine
maintenance
is
due
.
The
Oil
Service
indicator
signals
the
need
for
the
most
basic
levelof
routine
maintenance
.
BMW's
required
oil
service
speci-
fies
changing
the
engine
lubricating
oil
and
the
engine
oil
filter
after
the
engine
has
been
warmed
up
.
BMW-recommended
ad-
ditional
maintenance
for
this
service
is
listed
in
Table
a
.
NOTE-
For
reference,
the
BMW
Oil
Service
requirements
are
approximately
equivalent
to
the
maintenance
that
other
European
manufacturers
specify
at
intervals
with
a
maximum
of
every
7,500
miles
or6
months
.
CAUTION-
Be
sure
to
follow
the
ínstructions
forresetting
the
Oil
Service
indicator
fight
.
The
Inspection
indica-
tor
can
be
accidentally
reset
rendering
its
function
inaccurate
.
Inspection
l
and
Inspection
II
The
Inspection
indicator
signals
the
need
for
more
compre-
hensive
maintenance
and
Inspection
.
There
are
two
sets
of
in-
spection
requirements,
Inspection
I
and
Inspection
ll
.
These
inspections
alternate
throughout
a
car's
maintenance
history
.
If
the
last
Inspection
interval
was
Inspection
I,
the
next
Inspection
interval
(following
an
Oil
Service)
will
be
Inspection
ll,
the
next
after
that
will
be
Inspection
I,
and
so
on
.

Both
the
4-cylinder
and
6-cylinder
engines
use
a
distributor-
less
ignition
system
with
individual
ignition
coils
for
each
cylin-
der
.
FuelDelivery
Pressurized
fuel
from
the
in-tank
fuel
pump
is
injected
via
solenoid-type
fuel
injectors
.
The
ECM
controls
the
opening
and
closing
of
the
injectors
by
switchingthe
ground
side
of
each
injector
circuit
.
The
exact
amount
of
fuel
injected
is
de-
termined
by
the
amount
of
timethe
injectors
are
open
.
Cooling
System
Whenever
the
engine
is
running,
acoolant
pump
circulates
coolant
through
the
engine
and,
if
either
heater
control
valves
are
open,
through
the
heater
core
in
the
passenger
compart-
ment
.
The
coolant
absorbs
excess
heat
and
carries
it
to
the
ra-
diator
where
it
is
transferred
into
the
passing
airstream
.
A
thermostat
controls
the
flow
of
coolant
through
the
radiator
based
on
engine
temperature
.
Lubrication
System
The
lubrication
system
is
pressurized
whenever
theengine
is
running
.
The
oil
pump
draws
oil
through
a
pickup
in
the
bot-
tom
of
the
oil
pan,thenforces
it
through
a
replaceable
oil
filter
and
finto
the
engine
oíi
passages
.
On
4-cylinder
engines,
the
oil
pump
is
mounted
to
the
front
engine
cover
.
On
6-cylinder
engines,thechain-driven
oil
pump
is
bolted
to
the
bottom
of
the
cylinder
block
.
A
pressure
relief
valve
limits
the
maximum
system
pres-
sure
.
A
bypass
valve
prevents
the
oil
filter
from
bursting
and
insures
engine
lubrication
should
the
filter
become
plugged
.

119
Lubrication
System
for
