If parts illustrated in a diagram are MISSING from the listing, OR… they are noted with this symbol it means one of the following:

a) BMW considers the part obsolete or no longer available.

b) The part may not fit the specific model you are searching but fits a similar model that shares the same illustration.

c) There is simply an error in the Microfiche (Yes, though this is BMW’s official Parts Microfiche, there are occasionally errors or omissions!)
