Some
of
the
more
challenging
repairs
covered
in
this
manual

cal¡
for
the
use
of
BMW
special
tools
.
This,
however,
does
not

automatically
mean
that
thejob
is
too
complicated
or
out
of

reach
of
thenovice
.

Many
of
the
BMW
special
tools
mentioned
in
this
manual
are
simplythe
best
thing
to
use
to
do
thejob
correctly
.
In
these
cas-

es,
the
tool
is
identified
with
a
BMW
part
number
.
See
your
au-

thorized
BMW
dealer
parts
department
for
information
on
how

to
order
special
tools
.

There
are
some
jobs
for
which
expensive
special
tools
are

essential,
and
not
a
cost-effective
purchase
for
one-time
repair

by
the
do-it-yourself
owner
.
This
manual
includes
such
repairs

for
the
benefit
of
these
with
the
necessary
experience
and
ac-

cess
to
tools
.
For
the
do-it-yourselfer,
the
need
for
special
tools

is
noted
in
the
text,
and
whether
or
not
BMW
dealer
service
is

recommended
.

Evaporative
Control
System

The
fuel
tank
evaporative
control
system
is
used
to
vent
the

fuel
tank
to
a
charcoal
canister,
which
is
then
purgedby
en-

gine
vacuum
during
normal
engine
operatíon
.
This
controls

emission
of
raw

(fuel)
to

atmosphere
.
See

.

A
fuel
expansion
tank,
located
under
the
right
rear
fender,

traps
overflow
fuel
and
incorporates
extra
fuel
tank
plumbing
.

Startingwith
1996
models,
OBD
II
standards
require
that

the
fuel

evaporative
control
system
be
monitored
for

leaks
.
This
is
accomplished
usingthe
fuel
tankpressuresen-

sor,
the
ventshut
off
valve,
and
the
evaporative
purge
valve
.

NOTE-

On
most
early
cars(1992-1995),
the
charcoal
canister

is
in
the
engine
compartment
.
On
latercars,
the
char-
coal
canister
is
under
the
spare
tire
in
the
luggage
com-
partment
.

.
When
replacing
the
