Parts illustrated but NOT listed or parts noted with this symbol may be available! Click Here for full details.

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!)

In any case, if you need a part that you can’t find here, contact us! It’s likely that the part IS AVAILABLE from Bob's BMW. Most of the time these are the correct, genuine BMW parts that we regularly keep in stock. When original parts are no longer available, as can happen with older models, Bob’s has top quality replacements and reproductions in stock. And if the part you need isn’t currently in stock, we have many reliable sources in Europe, the US, and around the globe that we can tap to fill your request.

It’s what we do! Since 1981 Bob’s has been making it easy for you to get your parts – the right parts – every time.
