If I do a subversion update (sync the org-files to that computer) and then export to HTML on that computer, the previously working links do not work any more: there is no "#ID-..." in the link, in fact, the link is simply to the file that contains the link (not even the file I want to link to). Maybe Org-mode was not able to find the "id"?

The org manual says "[...] and one that is globally unique and works even if the entry is moved from file to file" implying that there is a strategy for looking for suitable candidates. I assume that Org-mode will look in currently open buffers first, but even if I load the correct target file, HTML export will not create the proper link. Perhaps a caching problem (I use "global-auto-revert-mode")?

How about an (optional) report after generating more complex HTML contents: maybe it could be another org-file with links to offending Org code (unresolved links, unknown macro names) and an easy-to-parse summary line for batch jobs ("done in 5.6s, *** 2 errors found")? I am perfectly willing to help with this, unfortunately, my elisp skills are fairly basic and I fear this requires some intimate knowledge of the export process.
I think you need to look in the ~/.emacs.d/.org-id-locations file. This
maps link ids to files.
