010-13

If
the
"CHECK
ENGI
NE"
warning
light
comes
on
or
flashes,
it
indicates
that
an
emissions-related
fault
has
occurred
.
Faults
suchas
a
failed
oxygen
sensor
or
a
faultyfuelinjector
can
tum

the
light
on,
causing
the
exhaust
or
evaporative
emissions
to

exceed
a
specified
limit
.
The
engine
can
be
safely
driven
with

the
light
on,
although
the
emission
systems
should
be
checked

assoonas
possible
.
See
100
Engine-General
for
more
infor-

mation
on
the
Check
Engine
Light
and
the
On-board
diagnostic

system
.

Headlights
and
instrument
panel
illuminationthat
are
dim
or

gradually
getting
dimmer
generally
indicate
a
problem
with
the

battery
or
charging
system
.
The
battery
charge
indicator
light

may
come
on
as
the
lights
are
dimming
.
In
either
case,
theen-

gine
and
accessories
are
running
off
of
the
battery
alone,
and

will
soon
discharge
it
altogether
.

If
possible,
do
not
stop
the
engine
unless
you
have
the
capa-

bility
to
jump
start
¡t
.
There
may
not
be
enough
power
in
the

starting
system
torestart
the
engine
.
Instead,turn
off
as
many

electrical
consumers
as
possible
.
This
will
reduce
the
current

drain
and
will
allow
thecar
to
be
driven
farther
before
you
lose

all
battery
power
.

TROUBLESHOOTING

The

consists
of
an
oil

switch
mounted
in
the
oil
circuit
and
an
instrument
panel
warn-

ing
light
.

CAUTION-

If
the
red
oil
pressurewarning
light
comes
on
or
flashes
on
while
driving,
always
assume
that
the
oil
pressure
is
low
.

To
perform
an
oíl
pressure
test,
BMW
specifies
special
tools
that
attach
to
thetop
of
the
oíl
filter
housing
.
The
following
pro-
cedure
works
well
using
standard
automotive
oil

testing
equipment
attached
to
the
oil

switch
port
in
the

.
In
some

however,
access
tothis

may
be
extremely
