w221 2013 s350 fuse chart
when hit any trunk button trunk unlock but not lifting up now.
This is how it works with my W221 2006 S500 EU-version :
Flat acc.battery ->open car with key ->startup engine-> recharge acc battery by driving around=>trunklock no worky at remote ,neither doorswitch nor at the trunk,so you're locked out of the trunk now. Shutdown engine.
Then lock with keyless or remote ,open with keyless or remote and your trunk release works again,magically.
Very strange indeed,but hey these are rolling computers so nothing amazes me at this point.
Hope my experience from today can solve your issue easier.
