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

.
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

.
For
the
do-it-yourselfer,
the
need
for
special
tools
is
noted
in
