Can you (temporarily) release the (2?) springs that flip up the trunk lid when the lock is released. Then even if the trunk lock pops open, your trunk should stay shut.
Just why this is happening has stumped me....
You might try removing fuse f8 from the trunk fusebox, and see what happens. This will take power from the left/right window antenna amplifiers. You might also lose the radio signal -not sure about that. But it should stop a spurious external signal triggering the CL system.
