UK E90 LCI 2009.

I've had the car for a year and it would always flash the side indicators twice when unlocking and once when locking. About a week ago, it stopped flashing when unlocking. This is with both keys. Lock and unlock functions work fine, just the indicators when I unlock don't flash anymore. I have checked the settings for each key on the odometer and the lights option is enabled. I've not messed around with any coding tools etc, so can't figure out how this happened.

You can try resetting the settings for the keys in the car's menu system. Sometimes a reset can fix minor software glitches. Also, you can check the wiring harness and connections related to the indicators. It's possible that loose or damaged wiring could disrupt the signal from the key to the indicator lights.
