Update 1: In the meantime, I had service done. The AC compressor was broken (after about 400km). Replacement free of charge. Thanks go out to Tesla Cologne.
Update 2: About three months later, a hint of the old problem is back. Not every time and only during cold nights but nonetheless... already preparing for the next visit to a service center.
Update 3: Yep, it's back. I'm a few weeks past my first 12 months with the car.
Update 4: Ok, huge props to Tesla. About 14 months after purchase I scheduled my second service appointment, this time in Düsseldorf. The guys there were just awesome. They looked quite deeply into the problem and found that the AC compressor fell victim to an entirely different problem. It turned out that the temperature sensors in the manifold were faulty and caused the AC compressor to go haywire. This killed the pump in both instances. Tesla Düsseldorf replaced the manifold and also the defective AC compressor which entirely fixed the problem.
