Don't worry guys, I figured it out!
(With some help)
If an aerdrome temporarliy lost the use of its navaid, but still had a TAF then you would obviously use LSALT +500 and 8km
So simple now!
And appaerntly there are place with TAFs but no approach
(I couldn't find any in my quick search through the ERSA yeseterday)
So there you go, i'll go home and shut up now!
