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 the job is too complicated
or out of
reach of thenovice .
Many of the BMW special tools mentioned in this manual are
simply the 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

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 .
