What's the Issue?

BMW AG has identified a concern with certain rear axle parts, specifically part number 33 10 8 881 536, intended for the 2025 BMW X1, X2, and 230i models. The issue involves oil accumulation found within the plastic packaging of these parts. This oil leakage is attributed to the vent valve, posing a risk of further oil loss.

This bulletin, identified as TEC792, mandates an inspection and return process for these affected components. The presence of oil in the packaging indicates a potential defect that requires immediate attention. Owners of a 2025 BMW X1, X2, or 230i should be aware of this issue.

Affected Parts and Identification

The specific rear axle part affected by this bulletin is identified by part number 33 10 8 881 536. This bulletin applies to all such parts that have been delivered and shipped and are found to contain oil accumulation in their plastic packaging.

Parts that do not show oil accumulation in their packaging are considered non-affected. Dealers and service centers are instructed to inspect inventory carefully to distinguish between affected and non-affected parts.

Important Warnings for Dealers and Owners

BMW has issued several critical warnings regarding these affected rear axle parts:

• "Affected available inventory must not be sold."

These warnings emphasize that affected parts cannot be repaired or reconditioned and must be removed from circulation. The "BMW X1 rear axle oil leak" issue necessitates careful handling to prevent further complications.
