2024 BMW X1 / X2 DKG Oil Service Required TSB

BMW has released Technical Service Bulletin (TSB) 28 01 25 to address a specific Check Control message (CCM) that alerts owners of 2024 BMW X1 (U11) and X2 (U10) vehicles about required maintenance for their double-clutch transmission (DKG). This bulletin clarifies the conditions under which the "Transmission oil service required" message appears and outlines the necessary steps for resolution. Owners searching for "2024 BMW X1 DKG oil service" will find this information relevant.

This TSB, identified as 28 01 25_U10 U11, details a routine maintenance task for the DKG system. It's crucial for owners to understand the implications of these messages and to follow the recommended service schedule to ensure the longevity and proper function of their vehicle's transmission.

Symptoms

Owners of affected 2024 BMW X1 and X2 vehicles may observe a Check Control message (CCM) on their display. The primary message is "Transmission oil service required" (ID 2120).

This initial warning typically triggers under one of two conditions: either the vehicle has accumulated between 60,000 miles (95,000 km) and 78,000 miles (125,000 km), or six years have passed since the vehicle's production date. The six-year interval is determined by the vehicle's production date, not the first registration or pre-delivery check. If the vehicle is driven approximately 1,900 miles (3,000 km) after the first CCM appears, a second, more urgent message will display: "Transmission fault!" (ID 368).

Cause

The root cause of these warning messages is the natural aging of the oil within the double-clutch transmission (DKG). Over time, and depending on the vehicle's usage and driving profile, the transmission oil degrades and reaches the end of its service life. This necessitates a regular "transmission oil change in the double clutch transmission" as part of routine maintenance.
