Quick update:

Called the service company today again and they were much more happy to help me today :). I talked for about fiften minutes about the issue and I now know that this sometimes happens. The engine, or actually the gearbox wears out and gets problem driving the glass door. Replacing it costs about 3000 SEK including labour. 

I have informed the seller but I have yet to hear back from him. 

I can try to catch a video of the problem an post on youtube for futher reference for anyone who might experience the same issue in the future.

good to know about this potential issue - thanks for the update :)

Quick update. Have not recorded the problem yet but I bought a floor stand and it works very well on it (less gravitational impact I guess). It looks better than I thought it would so I am happy with that, for now at least. 

Have also spoken with the seller and he offered me some money back towards the service cost.  

Update 2. Call me crazy but I actually bought a spare bs9000 that was freight damaged, which included a floor stand in good shape :). The freight damaged bs9000 has a glass door where the mounts have come lose(interesting to see that B&O has drop-proofed it with rubber-safetylines glued to the mounts so it won't fall down).  

Anyhow. Since it is sunday I decided to try the glass from my first bs9000 on the damaged one, just to see if it could rise the glass without a problem. It could not! 

This made me think and I have looked closely at the mounts. It seems that the metal mounts that fits into the bs9000 are disfigured after some time and I think this is the real issue. Perhaps a new glass panel will solve the problem? Not really sure. 

Perhaps I can glue the mounts back onto the glass door for the damaged bs9000 and se what happens? 

What would you guys do?

I should tell you that I am very tech savy =) and a bit odd.. perhaps :)
