If nothing else...pull the K112 relay and reinsert it (check for corrosion or other signs of trouble first, though). The k112 relay should be the very last relay in the cargo fuse box (I believe it's purple) closest to the right rear tail light.
In the faceift x5 (2004-2006 model year)...the K112 relay which controls the SCA open functions...is the purple relay on the far right in pic below in the rear cargo area fuse /relay box:

Qsilver, thanks for jumping in! I think you are onto something. I did pull the relay out and back in, as you suggested, but still no joy. There are no signs of corrosion. I did notice a few things though:
1. The actuator is definitely not working properly anymore. It no longer pulls the lift gate when I shut it. I think I do hear the lock engaging though when I lock.
2. The exterior button to open the lift gate is not functioning anymore
I use the remote mainly, especially after I installed the springs, so I did not notice.
The rubber seal over the button has dried up and deteriorated awhile back. I re-sealed it with silicone and learned to use the remote instead. At the time I went to the dealership and they explained it's the whole assembly that needed to be replaced. Was expensive (~250?) so I skipped it. Everything worked at the time so I resealed the rubber and called it good.
3. I am missing the middle relay from the picture! the light blue one. What is it for?
Could the relay be toast? What else can I check?
Thanks
