BMW is constantly updating and
improving their cars, often making
improvements during a given model
year. BMW may recommend a newer,
improved part as a replacement, and
your authorized dealer's parts
department will know about it and
provide it. The BMW parts organization
is best equipped to deal with any BMW
parts needs.

Non-returnable parts

Some parts cannot be returned, even
for credit. The best example is
electrical parts, which are almost
universally considered non-returnable.
Buy electrical parts carefully, and be as
sure as possible that a replacement is
needed, especially for expensive parts
such as electronic control units. It may
be wise to let an authorized BMW
dealer or other qualified shop confirm
your diagnosis before replacing an
expensive non-returnable part.
Information you need to know
Model. When ordering parts it is
important that you know the correct
model designation for your car. Models
covered in this E46 manual are 323i/Ci,
325i/Ci, 325Xi, 328i/Ci, 330i/Ci 330Xi in
Sedan, Coupe, Convertible and Sport
Wagon body styles.
Model year. This is not necessarily the
same as date of manufacture or date of
sale. A 1999 model may have been
manufactured in late 1998, and
perhaps not sold until early 2000. It is
still a 1999 model. Model years covered
by this manual are 1999 to 2001.
Date of manufacture. This information
is necessary when ordering
replacement parts or determining if any
