I looked today. Current status here is charitably described as "in flux":

- Rüdersdorfer Str is passable its whole length, though with very bad surface quality from Wedekindstr to Marchlewskistr. it has been passable since Easter so I assume the reopening isn't temporary.
- in Rüdersdorfer Str westbound by ALDI stands a Fahrzeugeverbot sign with exception of Feuerwehr und Grundstücke 57 & 69, as well as a speed limit of 10 km/h
- in Rüdersdorfer Str eastbound by Berghain stands a Fahrzeugeverbot sign with no exceptions noted, and a speed limit of 10 km/h
- in Wedekindstr southwest-bound stands, as before, a "right turn only" sign excepting Feuerwehr
- in Rüdersdorfer Str southeast-bound there is no more turn restriction sign

I would suggest the following tagging:
- Rüdersdorfer Str from Wedekindstr to Marchlewskistr is marked entirely access=destination, smoothness=bad, maxspeed=10
- turn restriction relations are removed from Rüdersdorfer/Wedekindstr intersection given contradictory signage right now, and routers depend on access=destination tag
