2025 BMW X1 Sunroof Moves Slowly or Not At All TSB

Owners of the 2025 BMW X1 Sport Activity Vehicle (U11 E-Series) may experience issues with their panoramic sunroof. Specifically, the sunroof glass panel might open or close slowly, or it may not move at all. This condition affects vehicles equipped with the 402 Panoramic Moonroof option.

Symptoms

The primary symptom is that "The sunroof opens/closes slowly, or does not move at all." This directly impacts the functionality and convenience of the panoramic sunroof system in your 2025 BMW X1.

Cause

The root cause for the panoramic sunroof's sluggish or non-operational movement is identified as contamination on the outer track(s) of the sunroof cassette. This contamination can affect either one or both sides of the sunroof cassette, hindering the smooth operation of the glass panels.
