Great finding based on the older 7 digit numbers.

Search by BMW part # (7 or 11 digit) or select your vehicle first
Do not include spaces, dashes, or periods.
When looking at your BMW part, you should be able to find at least a partial 7 digit BMW part number. Some BMW parts will also include the 4 digit group number prior to this 7 digit number. You can search here with either the full 11 digit BMW part number or just the 7 digit BMW number, but your search results will include the full 11 digit BMW part number.
