I can't see this being the DME relay (K6300) - although I suppose a catastrophic internal fault might cause problems. It's pretty unlikely though, as the most likely fault (an internal short) would likely be present at all times, not just when you try to start the car. The fact that the fuse blows when the relay activates indicates that the relay is in fact most likely working correctly.

The DME relay is however possibly connecting the faulty module to F105 when the relay activates, causing F105 to blow. Because of this, removing the DME relay from it's socket may well remove the overload problem but not because the DME is fault (although that is possible) but because removing the DME isolates the fault from F105.

Think of it like water - there is a big leak. Removing the DME connection (a tap in this analogy) stops the leak but only because it stops water flowing down some paths TO the leak.
