Hello forum, I have a 650i LCI from 2008. For a week I have been experiencing electrical problems after turning off the car. When I turn it off, the headlights, tail lights and break light keep flickering for a while and then they keep on so I have to turn the switch on and off until they finally turn off. According to my mechanics diagnosis, a CAS module error appears on the scanner. I would like to know your opinion, what else can I review or discard before making a decision about the CAS module change.
