Initial publication

This bulletin applies to 2022 – 2024 Q4 with software 0460 and 0465 (address word 0008) only.
Customer States:
The lighting on the buttons for the front A/C display control head will occasionally flicker. During these episodes
the control head will not accept any input.
Workshop Findings:
While this symptom is sporadic in nature, it is possible to reproduce.

Technical Background
During the routine LIN communication between the front air conditioning control head (E87) and the 08 – HVAC
Electronics control module (J979) a dissonance can occur in the communication LIN and results in sporadic
flickering of the control head lighting.

Production Solution
This bulletin will be updated when more information is available. A solution is currently under development.
