My BMW Z4 has started to have the classic symptoms of a bad General Module 5 - the doors have a problem unlocking. I have determined that it's not the actuators. From the videos I've watched, it doesn't seem to be a big deal to repair, just unsoldering the old Tyco relays and resoldering the new ones. My hobby is vintage electronic repair so soldering is not an issue. Buying a new one is a no-go because it will need to be reprogrammed.
Any words of advice by anyone who have made this repair?
