Control Unit - BMW 5er E34 - lamp control module 2 defective

Fault in the BMW lamp control module 2.

Low beam, high beam or fog lights suddenly stop working, even though the bulbs are intact. The light flickers or briefly goes out while driving and then comes back on. Only one headlight illuminates, while the other remains dark.
Messages such as ‘low beam defective’ or ‘parking light defective’ are displayed in the on-board computer (Check Control), even though all lights are illuminated.
