If the ids change it makes diff processing a bit difficult...  

Or perhaps I misunderstand what you mean here?

You should never assume that OSM Way IDs (or indeed any IDs) remain 
unchanged. The "data" layer on www.openstreetmap.org is your friend if 
you want to find out the history of a particular stretch of motorway.

(Furthermore, if you are from Germany and want to inquire about a piece 
of German motorway, you might actually get more responses if you ask on 
talk-de!)

Bye
