BMW HVAC Evaporator Part Number & Supersession Tracker

Parts catalogs help identify which evaporator is listed for a BMW application — but catalog data is secondary evidence, fitment is VIN-specific, and a superseded number is not proof of a defect. This tracker records what the catalogs say, what registry documents show, and the difference between the two.

LIMITATION — A superseding part number does not, by itself, establish that the earlier part was defective or why the change occurred.

The founder-case final BMW Fresno repair order (August 18, 2026) identifies the installed evaporator as 64-11-5-B3A-5E0, normalising to 64115B3A5E0. Associated hardware on the same order: gasket rings 64539284019 and 64539284020, and R-1234yf line item 83192446563.
Fitment must be verified by VIN. Third-party catalog data can be incomplete or change over time. One documented installed superseding part does not establish why BMW superseded the earlier number, and does not establish that the earlier part was defective.
READING A SUPERSESSION

Why part numbers change

Manufacturers supersede part numbers for many reasons: engineering changes, supplier or supply-chain changes, part consolidation across models, packaging or catalog maintenance. The existence of a newer number establishes only that the catalog now points somewhere else.

MANDATORY CAVEAT

A superseding part number does not, by itself, establish that the earlier part was defective or that the change was made to correct a failure mode. Fitment and supersession must be verified by VIN.

What would raise evidentiary value: registry invoices identifying which part number was actually installed, dated before and after the supersession — documentation, not inference.

DOCUMENT-DRIVEN

What gets added, and when

EVENTTRACKER ACTION
A reviewed invoice identifies an installed part numberCount appears as “Registry documents reporting this part number: n=X”
A catalog listing changesEntry updated with new access date; prior state noted
An invoice does not identify the partNo inference is made — the field stays empty
A reliable catalog source for the superseding number becomes availableReverse-lookup entry added for 64115B3A5E0
A reviewed repair order identifies installed hardware beyond the evaporator itselfRecorded as associated hardware, never as evidence about the evaporator’s condition

Your invoice may hold the missing part number.

If your repair order or invoice identifies the evaporator part installed in your BMW, that single line item advances the record.
