BMW's part number system is well-organized and follows a
specific structure that helps identify parts accurately. The part numbers (also
known as Teilenummer in German) are typically 11 digits long, divided
into three segments:
Structure of a BMW Part Number:
- First
three digits (Group number):
- This
part of the number usually represents the general part group. For
example, the "11" group might be related to the engine,
"33" relates to the suspension, and "51" relates to
bodywork.
- Middle
four digits (Subgroup number):
- These
digits specify the particular subgroup within the part group. This
refines the part's categorization further. For instance, in the engine
category, this section might refer to a specific type of component like
an oil pump or gasket.
- Last
four digits (Sequential or specific part number):
- This
part is often unique to the exact part, its variant, or design for a
specific vehicle model. It can be associated with revisions or variations
of a part for different models, years, or configurations.
Example:
A BMW part number such as 33 12 1 094 622 might break
down like this:
- 33
= Rear axle and suspension parts.
- 12
= Subcategory of parts, such as suspension arms or bushings.
- 1
094 622 = The specific part (a suspension arm, for example).
Additional Information:
- Supercession
of part numbers: BMW often updates part numbers over time as parts are
modified or improved. If a part is updated, a new part number may be
assigned, but the old one will reference the new one in catalogs.
- Prefixes:
Some part numbers have prefixes, indicating special types of parts (e.g.,
aftermarket, accessory kits).
- Suffixes:
There can be suffixes like "-02" or "-03" for
different versions of the same part, sometimes indicating a change in
material, supplier, or design.
BMW's parts catalog system uses these part numbers for easy
identification, ensuring that the correct component is found for a specific
vehicle. This numbering scheme is consistent throughout the range of BMW's
parts, including engines, electrical systems, interior components, and more.
