My retrofitted alarm on E92 beeps upon lock & unlock, lights also flash on lock, & welcome lights come on upon unlock.
I added the alarm to my VO though (which is really the correct way to do it) all the alarm functions, panic, etc. were automatically enabled after VO update.
Yes, you can go into iDrive or use your stalk to control if & when the beeps sound and/or light flash - but all these features were already ON once I updated my VO.
