Just a thought and maybe not relevant to your problem but getting the right magnetic deviation adjustment when setting up your mount can be a bit confusing. As you probably know, and according to an app. I found on the Internet, your magnetic deviation in Merbein is 9º 14' East. This means that when you use a magnetic compass and point it towards the South true South is to the left of the South indicated by the compass. My apologies if you already have this covered, but if you inadvertently worked on the basis that true South was to the right of the South indicated by the compass your cumulative error would be 18º 28'. If you use a compass that has a magnetic deviation bezel, you would set it so that the compass' fore-aft marking line is set just to the right of the 350º mark (i.e. at about 351º) on the bezel. The attached images show what I mean by the fore-aft marking line and using the compass with your magnetic deviation set to 9º 14' East.
