2025 BMW Oil Line Return Bulletin TEC781

BMW has issued Parts Bulletin C32-0825-0643, identified as TEC781 OIL LINE RETURN, concerning certain oil line part numbers. This bulletin, dated August 18, 2025, requires BMW dealerships to inspect their inventory and return specific oil line part numbers with older AI index numbers. This proactive measure ensures that only the most current and compliant parts are used for service and repairs, impacting the 2025 BMW oil line return process.

The bulletin specifically targets oil line part numbers 11 42 7 952 808 and 11 42 8 489 608. The purpose of this action is to remove parts with older AI (index) numbers that are no longer deemed suitable for use in 2025 BMW models.

Important Warnings

BMW has explicitly stated that "Affected available inventory must not be sold." This is a critical directive to prevent the installation of potentially non-compliant parts into vehicles.

Affected Part Numbers

The TEC781 OIL LINE RETURN bulletin identifies specific oil line part numbers and their corresponding AI index numbers that are considered affected and should be returned. The 'AI' refers to the 'Ausführungsindex' or 'Execution Index', which denotes different revisions or versions of a part. Parts with an older index are not suitable for use.

• PN 7952808 AI03 and lower
• PN 8489608 AI04 and lower

Parts OK for Use

Conversely, newer versions of these oil lines, identified by their updated AI index numbers, are approved for use and do not need to be returned. These are the parts that should be used for any necessary replacements or new installations.

• PN 7952808 AI04
• PN 8489608 AI05

When reordering, it is essential to ensure that the correct, non-affected part numbers are ordered to replace the returned inventory.

Detailed Return Procedure

To facilitate the return of affected oil lines, BMW has outlined a precise procedure for dealerships. All affected part(s) must be returned to their facing Regional Distribution Center (RDC). The return process requires submitting a YR26 damage claim. The specific order reason for this claim must be "BM2". Dealers are also required to enter a valid BMW delivery and delivery item number as part of the claim. Crucially, the text of the TEC claim must explicitly include "TEC781" to ensure proper processing. If a delivery number cannot be located, an IDS ticket should be submitted for assistance. This ticket should be directed to "Parts Logistics>Returns>Claims>Quality>Claims".

Visual Identification of Parts

The bulletin includes a visual aid to help distinguish between affected and non-affected parts. The image shows an example of a part with its AI index number clearly visible, such as "8489608-05 0128". The '-05' in this example corresponds to the AI05 index, indicating it is an approved part. Technicians should carefully inspect the markings on the oil lines to confirm their AI index number before returning or installing them.

Key Dates and Deadlines

This 2025 BMW oil line return initiative is active for a defined period. The bulletin is valid from August 18, 2025, through September 01, 2025. Dealers must adhere to specific deadlines: the deadline for filing a claim under TEC781 is September 01, 2025. Furthermore, all affected parts must be physically returned to the Regional Distribution Center (RDC) no later than September 15, 2025.
