My experience with a private landlord in germany is not good. We spent months trying to get them to answer on a question on the windows; can we fix the blinders ourselves or do they want us to use some contractor? No answer. Calls, whatsapp, letters, no answer. We contact the tenants union which said that they can sent a proper legal letter they have to reply to, the lawyer at the union also added that we will use a contractor and take it out of the rent. Now we got a letter back, from their lawyer, no answer on what we should do, just a threat that they will sue us if any rent will go missing. We just gave up.

Let them sue, they will lose. It’s an empty threat meant to deter you
Actually it seems to depend on what’s broken: https://www.mietrecht.org/kleinreparaturen/ist-ein-defekter-rollladen-oder-rollladengurt-eine-kleinreparatur/
But there are precedent cases. If it’s not a small repair (“Kleinreparatur”), you are good to go
