2022-2023 BMW iX Multifunction Display Horizontal Distortion

Symptoms

Owners of affected BMW iX vehicles may observe a "single horizontal line of distortion on the Multifunction Display screen" (which includes both the instrument cluster/kombi and the Central Information Display). This line rapidly and repeatedly moves from the bottom to the top of the screen. The "BMW iX display distortion" is often subtle and becomes more noticeable when the display shows bright backgrounds, such as the Weather App.

Cause

The root cause of this display issue is an incorrect firmware setting for the indigo driver within certain Multifunctional Displays. This specifically affects InnoLux-produced displays with a firmware version of FW134 or lower.

Important Warnings

BMW Service Information Bulletin 65 32 23 clarifies that this specific issue is not related to other display problems. This bulletin does not address the loss of individual pixels, a stationary defect in the display (such as a solid colored line), or a flickering "on and off" of the entire display. It exclusively pertains to the subtle horizontal distortion described.

Furthermore, if your vehicle's Multifunctional Display is an InnoLux product with firmware version FW135 or higher, or if it was produced by a different manufacturer, then any distortion you encounter does not fall under the scope of this bulletin. In such cases, standard diagnostic procedures should be followed.

For technicians, it is crucial that all defective parts inventory related to this SIB has been cleared. If there are any uncertainties regarding correct firmware date and identification, reference Parts Information Bulletin 06 50 23.
