"Storage Space Running Out" Message

BMW Service Information Bulletin SIB 65 07 26, identified by NHTSA ID B650726, addresses the "Storage space running out" message appearing on the central information display (CID) in certain 2026 BMW X1 models.

This can be accompanied by Dynamic Stability Control malfunction warnings and specific fault codes. The bulletin provides a comprehensive repair procedure for this mechanical issue.

DKG Transmission Oil Service and Fault Warnings

Owners of 2024-2026 BMW X1 and X2 models equipped with a Double Clutch Transmission (DKG) might encounter a "Transmission oil service required" message (ID 2120) or a more critical "Transmission fault!" (ID 368). BMW Service Information Bulletin SIB 28 01 25 (NHTSA ID B280125) outlines the conditions triggering these messages and the necessary service procedures to address them.

Another significant bulletin, SIB 12 03 24 (NHTSA ID B120324), addresses an "Engine Malfunction Warning" and fault code FC 034AEF, indicating an "Exhaust Cold Start, Not Controllable" condition. This issue affects 2024 and 2025 BMW X1 and X2 models and is typically resolved through a DME software update using the ISTA diagnostic system.

What BMW X1 Owners Should Do

1. Monitor Warning Messages: Pay close attention to any messages appearing on your Central Information Display (CID), such as "Storage space running out," "Engine Malfunction Warning," "Transmission oil service required," or "Transmission fault!". These often indicate an underlying issue addressed by a service bulletin.
2. Listen for Unusual Noises: Be aware of any new or unusual noises, particularly humming or clicking sounds from the rear axle, which could point to wheel bearing issues.
3. Contact Your BMW Dealer: If you experience any of the symptoms or warning messages described in these bulletins, contact your authorized BMW dealer for diagnosis. Provide them with a clear description of the issue.
4. Inquire About Software Updates: Many issues, especially those related to infotainment or engine management, are resolved with software updates. Ask your dealer if any relevant software updates apply to your vehicle during routine service visits.
